Spider & Jaw Equipment Couplings | Spider & Jaw Couplings
Select The Best Spider Jaw Coupling for Your Application
Torsionally stiff spider couplings provide reliable, smooth power transmission without torsional oscillation or vibration, providing advanced protection for your application needs. Miki Pulley offers four spider and jaw coupling options to meet your application requirements.- ALS-R – Our ALS-R curved hub shaft jaw coupling features a Curved-Jaw profile design, offering a slight pre-compression of the spider and Type “R” elastomer spider element while providing 97 shore hardness. This hub aluminum jaw coupling model offers high torque, high torsional stiffness, and zero backlash, with a limited capacity for shaft misalignment.
- ALS-Y – Featuring a curved-jaw profile, the ALS-Y hub aluminum jaw coupling offers a slight pre-compression of the spider and Type “Y” elastomer spider element while providing 90 shore hardness. This model offers a good balance of performance and flexibility for shaft misalignment. The tightly fit spider element creates a zero-backlash connection and has a moderate level of torsional stiffness for system responsiveness.
- ALS-B – Manufactured with a straight jaw profile and Type “B” elastomer spider element while providing 97 shore hardness, the ALS-B hub aluminum split spider shaft coupling offers a looser fit for handling more significant amounts of shaft misalignment with minimal backlash while delivering a high torque capacity.
- AL SPRFLEX - The AL SPRFLEX curved hub shaft jaw coupling features a straight jaw profile and (NBR) Nitrile rubber spider element, offering high flexibility, high dampening, and low backlash operation. SPRFLEX couplings are waterproof and oilproof, providing advanced deterioration protection.
