Sure Flex Coupling Sleeves

Sure-Flex Plus couplings use EPDM, neoprene, Hytrel and urethane made flexible elastomer sleeves for transmitting torque and accommodating shaft misalignments. Sure-Flex Plus couplings provide excellent torsional flexibility owing to their 4-way flexing action for absorbing all types of misalignments, shocks, vibrations & end floats. The uniquely designed teeth of these Sure-Flex Plus couplings allow the accommodation of angular misalignments without wear, which can be achieved with callipers or a scale. These sleeve couplings absorb parallel misalignments without wear and noticeable energy loss. The lateral flexibility of these sleeve couplings reduces radial bearing loads associated with the parallel misalignment.
Sure-Flex Plus couplings can be used in applications with limited axial shaft movements. These couplings offer 30% increased torque rating for ensuring minimum required maintenance and have over 3x longer service life than most competitive couplings. Sure-Flex Plus sleeves can be entirely interchanged with existing flanges, thereby delivering performance improvement.

Frequently Asked Questions

Where are Lovejoy LS Series inserts used?

These inserts are designed to accommodate angular and parallel shaft misalignment, ensuring smooth and efficient power transmission in industrial systems.

Are Martin super pack seals easy to install?

Martin super pack seals are designed for effortless installation and maintenance. They are engineered to seamlessly fit with standard coupling components, enabling hassle-free assembly and disassembly. These seals require minimal maintenance to ensure optimal performance. Regular inspection and replacement, as needed, help maintain the seal's integrity and prevent potential leaks or performance problems.

Is a coupling a permanent joint?

A coupling is a mechanical device used for holding two rotating shafts together. It is a permanent joint, unlike a clutch that can be disengaged when the operator requires it to. With the help of couplings, you can join two shafts that are colinear, intersecting or parallel.
