JAW COUPLING

Jaw Couplings for Smooth Power Transmission

AniGears AJ Series Jaw Couplings are torsionally flexible, fail-safe couplings designed to transmit torque through interlocking precision-machined jaws and a resilient elastomer element (spider).

They provide reliable power transmission while absorbing shock loads and damping vibration.

The design ensures continuous drive even in case of elastomer failure (metal-to-metal contact between jaws), making them ideal for industrial applications where reliability and simplicity are essential.

AniGears Jaw Couplings are compact, easy to install, and require no lubrication, offering long life with minimal maintenance.

They are suitable for both horizontal and vertical installations, and are widely used across mechanical drives where moderate torque, flexibility, and vibration damping are required.

The AJ Series is available in four variants to suit diverse mounting and maintenance requirements:

Installation Steps

Easy Installation Steps

Clean all components thoroughly before assembly.
Mount hubs on shafts ensuring full key engagement.
Align shafts and maintain equal gap between hub jaws.
Insert the elastomer spider ensuring full seating between jaws.
For AJW / AJL / AJS types, ensure clamping rings or fasteners are securely tightened.
Check alignment after installation.

Maintenance

Easy Maintenance

Periodically inspect elastomer for wear, cracks, or hardening.
Replace if swelling, tearing, or excessive wear is observed.
Recheck alignment periodically.
No lubrication required.

Features & Advantages

Why Choose This Product
