Overview
The Rexnord 10287337 is an E30-sized elastomeric coupling element from the Omega series. This Rexnord 10287337 coupling features a close-coupled design and is manufactured from orange urethane material to absorb shock loads and accommodate shaft misalignment. With a continuous torque rating of 3650 in-lbs (412 Nm) and maximum speed rating of 5800 rpm, the E30 element is suitable for moderate-duty industrial applications including pump drives, fan motors, and general machinery coupling.
