Consider the Sure-Flex® flexible shaft coupling range available from Abssac, which was designed specifically with that industry in mind. With large stocks kept, we offer an excellent solution to your pump coupling requirements. The easy to fit Sure-Flex® elastomeric shaft couplings rely on a proven element produced from a elastic polymer, to absorb the shaft misalignments but also transmit torque whilst simultaneously dealing with shock and vibration. Sure-Flex® shaft couplings can be installed quickly and easily because there are no bolts, gaskets, covers or seals. Alignment can be checked with a straight edge placed across the outside of the precision machined flanges. No special tools are needed for installation, alignment or removal.
No lubrication, trouble free operation…
The teeth of the sleeve lock into the teeth of the flanges without clamps or screws, tightening under torque to provide smooth transmission of power. Since there is no rubbing action of metal against rubber to cause wear, the couplings are not affected by abrasives, dirt or moisture. This eliminates the need for lubrication or maintenance, whilst providing clean dependable, quiet performance.”
The four way flexing action….
The 4-way flexing action absorbs virtually all types of shock, misalignment and end float. With Sure-Flex couplings, the need for lubrication and maintenance is also eliminated. As a result, the couplings provide clean, dependable and quiet performance for a variety of applications.
Flexing action #1 -TORSIONAL Flexibility !
Sure-Flex coupling sleeves have an exceptional ability to absorb torsional shock and dampen torsional vibrations. The EPDM and Neoprene sleeves wind-up approximately 15° torsionally at their rated torque. HYTREL sleeves will wind-up about 7°.
Flexing action #2 - ANGULAR Flexibility !
The unique design of the Sure-Flex coupling's teeth allows for the absorption of angular misalignment without wear. These limits allow for the alignment of the coupling using only a scale and calipers.
Flexing action #3 - PARALLEL Flexibility !
Parallel misalignment is absorbed without wear or appreciable energy losses. The lateral flexibility of the coupling sleeve minimizes radial bearing loads normally associated with parallel misalignment. This feature also allows for easier installation by the use of components bored for slip fits without fretting corrosion occurring at the shaft. Only a straight-edge and feeler gauge are required to obtain these limits.
Flexing action #4 - AXIAL Flexibility !
Sure-Flex couplings may be used in applications where there are limited axial shaft movements. The axial compressibility of the EPDM and Neoprene sleeves allows for shaft end-float without the absolute transfer of thrust loads.
30 years of product knowledge combined with a large stock of Sure-Flex Couplings and Sleeves provides a great basic shaft coupling solution.
With knowledgeable staff always available, we stock and supply the Sure-Flex® elastomeric shaft coupling. 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. EPDM and Neoprene sleeves have excellent dampening properties where as the HYTREL sleeves are for higher torques and petrochemical resistance.
