Jaw Couplings

A new six-pin jaw coupling takes only 5 to 15 min to remove and replace.

This reportedly compares to up to a few hours needed to replace competitive elastomeric couplings. The JIS 6 Pin coupling uses a standard jaw hub and needs no tools to remove or install. It works even with 2° angular misalignments and 0.030 to 0.094-in. parallel misalignments. The coupling is made from a 50 Shore-D urethane that withstands temperatures to 200°F (93°C). Its retaining ring is cast stainless steel and it can be used with aluminum-jaw-coupling hubs for AL090/95, AL099, 100, and AL110. The original JIS locking ring is interchangeable with the new JIS 6 Pin elastomer. Parts resist oil, dirt, sand, moisture, and grease.
