Product Description

The RULAND MANUFACTURING Jaw Coupling Spider is a zero-backlash curved jaw spider with a 1 5/16 in outside diameter. It is rated for 0.1110 hp and a maximum speed of 8,000 RPM, and is made of 92A material (MPN JD21/33-92Y).

Frequently Asked Questions

What is a RULAND MANUFACTURING Jaw Coupling Spider used for?

A RULAND MANUFACTURING Jaw Coupling Spider is used to transmit torque between two shafts while accommodating minor misalignment. It is commonly applied in industrial power transmission systems, such as pumps, gearboxes, and conveyors, where zero-backlash and vibration damping are required.

What are the specifications of the RULAND MANUFACTURING Jaw Coupling Spider JD21/33-92Y?

The RULAND MANUFACTURING Jaw Coupling Spider JD21/33-92Y has a 1 5/16 in outside diameter, a maximum speed of 8,000 RPM, and a power rating of 0.1110 hp. It is made of 92A material and is an inch-size, zero-backlash curved jaw spider.

Where to buy RULAND MANUFACTURING Jaw Coupling Spiders worldwide?
