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 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.
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.
If you are looking for enhanced linear performance within your application, through trusted engineering support then the satellite roller screw program is worth considering. With a proven pedigree in application placement, the satellite roller screw program offers a unique precision linear device, that accurately transforms rotary movement into a linear motion.
Utilising, internally captivated threaded rollers that sit between the screw and the nut dramatically increases the high number of points of contact with the bearing system. This mechanical advantage enables satellite roller screws to support very heavy loads with precise and reliable motion. Meticulous attention to detail during manufacture, backed up with honed experience, delivers a formidable linear package.
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. Bore sizes from 4mm to 50mm as standard. Other bore sizes including keyways are available on request.
