The jaw coupling design has been used as a versatile application option, delivering a robust design and dampening features. The simple construction effectively sandwiches the centre of the shaft coupling using an element (or spider; made of polyurethane elastomer) between two hubs. The Elements are available in two different hardnesses so that a selection dependant on torque transmission responsiveness and amount of misalignment can be made. The polyurethane elastomer used in the element enables double the torque transmission of our previous jaw coupling (Miki Pulley comparison) and since the design pre-compresses the element, it can also be used to deliver rotation without backlash. Aluminum alloy is used as the hub material. The hub may be coupled to the shaft either by key way or by integral clamp.

The revolutionary high helix multi-start lead screws can offer leads of up to 6 x the diameter of the screw. This multi-start lead screw product provides high linear nut speeds from low rotational screw speeds. Aimed at replacing timing belt mechanisms or executing fast and reliable linear motion the efficient conversation of linear to rotary movement makes this unique product usable in many applications. Formed by the cold rolled forming process, the screws are proving to be a superb economical solution for high speed linear applications. The video shows the comparison of the distance the nut will travel for one revolution of the screw between a fine thread and fast high helix thread.

With decades of product knowledge combined with a large stock of Sure-Flex Couplings and Sleeves provides a great basic shaft coupling solution. Mix that with knowledgeable staff who are always available, and you have a great combination. The basic coupling uses two cast hubs available pre-bored or pilot bored and a proven centre element produced from a elastic polymer, to compensate for arduous shaft misalignments. The proven product delivers reliable torque transmission whilst simultaneously dealing with shock and vibration.

When the application requires a direct and solid shaft connection and that shaft misalignments during operation are minimal, then the ABR solid or rigid type couplings can be used. To suit shafts from 6mm up to 50mm in diameter as standard.A solid compression-type coupling or rigid coupling as it is sometimes termed has no flexibility but can effectively be used to connect two shafts to make a permanent joint. The solid coupling is usually designed to be capable of transmitting the full torque load capacity of the shaft.

A universal joint is a mechanical device that allows two shafts not in line with each other limited freedom of movement in any direction whilst transmitting rotary motion.Available in alloy steel, stainless steel or special materials, the single joint configuration can accept up to 25 degrees of angular misalignment where as the double joint designs can accept up to 50 degrees of shaft misalignment. Model designs can include needle bearings, hardened bushes or plain pin, depending on torque and speed requirements.

ABSSAC is an established supplier of miniature precision lead screws, encompassing power and high helix thread forms. With well over 3 decades of application experience they have been assisting engineers specify the correct linear product into an ever expanding range of applications. With a range of matching nuts to suit a myriad of performances as well as the facility of a fast turnaround machine shop allowing the lead screw and nut program to be delivered, ready to fit. Using the machine shop also reduces customer scrap rates. Find the right product for the right price, including support bearings, racks and splines and other related ancillary products.

The Transport Industrial ball screw range effectively converts high torque rotary input into precise high load linear movement for the more arduous applications. All transport ball screws can be delivered cut to length and if required, machined ready to fit into the required support bearing mounts. Utilising the recirculating ball bearing nut technology as the base of the product, the Industrial class ball screws encompass screw diameters from 12mm up to 80mm as standard with C7 accuracy. Leads of 1mm to 50mm are available through a large range of ball nut designs which in many any cases utilise multiple ball circuits to achieve greater load capacities. Typically the Transport ball screws are rated for millions of mm’s of travel at the rated dynamic load. This is the load at which 90% of a group of identical ball screws will run without flaking for their lifetime. However, they will travel farther than this at lower limits.

With one of the most diverse and capable ball screw ranges on the market allows ABSSAC to be considered for a large breadth of linear challenges. The choice empowers the capability to meet most linear challenges head on, but most importantly, within budget. As an established supplier of ball screws, including support bearings and other related ancillary products and provides the expertise in assuring engineers that they are specifying the correct linear products for their applications. The low friction within ball screw designs means that a high mechanical efficiency is delivered compared to that of lead screw designs, that ABSSAC also supplies. A typical ball screw may be 90 percent efficient, versus 50 percent for an equivalent sized lead screw. Therefore, ball screw specification is often a result of an application requirement to have smooth, accurate and perhaps fast, repeatable linear movement.

POWER Leadscrews are an excellent and reliable way of converting rotary motion into a linear motion. The speed, the load and the accuracy of position has a direct effect on the form and physical size of the lead screw and nut design. If you use leadscrews and nuts or perhaps you are considering the product within your designs, then give ABSSAC a call. We stock lead screws for industrial through to precision applications and have knowledgeable sales staff on hand to help with your selection. Our POWER SCREWS are suited to the more industrial type applications where lead accuracy is in the range of 0.1mm per 300mm. All POWER SCREW products can be supplied with a range of flanged, cylindrical and hex style nuts in Stainless Steel, Steel, Bronze and Plastic. Stocking up to 3 meter lengths of lead screw diameters of 12mm, 16mm, 20mm, 22mm, 24mm, 30mm, 36mm, 40mm and 50mm in both right and left handed formats. ABSSAC offers a complete turn key machining options on all of the screws to fit radial or thrust bearing units, which can also be supplied at very competitive prices.

With a traditional recirculating ball screw design, the captivated ball bearings within the nut housing transfer the load (force) between the screw and nut. This ordinarily means that in order to increase the load capacity, but remain with the same sized screw; you have to change the ball nuts physical parameters. Firstly, an increase in the amount of ball bearings physically touching the load surface of screw and nut within the nut housing will increase its load capacity. This can be done by increasing the amount of times the ball bearings recirculate within the ball nut housing, but the playoff of this change normally means a larger diameter nut housing or a longer nut housing. To this effect, the ball nut size versus its load capacity will always be apposing each other. It is true to say that all these options ultimately increase the load capacity, but in every case there is still a limitation of the actual load bearing surface area per ball bearing. This is where the satellite roller screw has a large advantage, which ultimately translates into a high load transfer capability.A satellite roller screw employs matched rollers to rotate (or satellite as the product name suggests) around the screw thread during actuation instead of ball bearings. By design, there is an immediate increase in the physical amount of contact points on the screw that can support a load compared with that of the same diameter ball screw. The satellite roller screw is therefore primarily chosen as part of a transition within a new or existing design to achieve greater load capacity and greater linear positional accuracy, in the smallest envelope space.The admissible static and dynamic load capacities are therefore considerably higher than that of ball screw for the same diameter. In fact the static load can be 3 times greater than that of ball screws and as a consequence, their lifespan can be up to 15 times longer. The many points of contact also give a satellite roller screw greater rigidity and shock tolerance than a ball screw without a compromise to friction or efficiency.

Lead screws are an excellent and reliable way of converting rotary motion into a linear motion. The speed, the load and the accuracy of position has a direct effect on the form and physical size of the lead screw and nut design. If you use lead screws and nuts or perhaps you are considering the product within your designs, then give ABSSAC a call. Most common thread forms are the acme or trapezoidal but ABSSAC can supply multi-start or special thread profile requirements as well as auger mixing screws and self reversing screw formats. In addition to the range of lead screws a complete range of plastic, steel or bronze nuts are available, which are tapped and matched to the screw, can be supplied. The lead screws can be supplied in a machined, rolled or whirled format, using Steel, Stainless Steel or in some cases Aluminium or Bronze. Combine this with the ability to offer further journal end machining, gun drilling, screw hardening and special coating treatments give ABSSAC the competitive edge.

ABSSAC's self-reversing screw product does not require the driven screw to change its direction of rotation to enable the nut to return to its original start position. The reciprocated bi-directional movement is achieved by using a follower blade in the nut, that is matched to the particular groove width and screw turn round on the screw. (Our self reversing screws, do not utilise ball bearings in their linear travel). The video shows the basic mechanics of the design we utilise. www.abssac.co.uk
