AL Type – Aluminum Jaw Coupling
- Lightweight aluminum version of the industry standard shaft coupling
- Interchangeable with L and SS line of hubs (except AL150)
- Corrosion resistant (finished bores passivated for additional protection)
- Accommodates for angular and parallel shaft misalignment
- Fail-safe – will still perform if elastomer “spider” fails
- No metal to metal contact
- Resistant to oil, dirt, sand, moisture, and grease

Description
Dimensional Data:
A full AL Type coupling is comprised of 3 parts:
- 2 aluminum hubs (with set screw)
- 1 elastomer spider (SOX, Urethane, Hytrel®, or Bronze)
Spider Perfromance Data:
SOX (NBR) Rubber (Standard Insert)
- Nitrile Butadiene (Buna N) Rubber is a flexible elastomer material that is oil resistant, resembles natural rubber in resilience and elasticity.
Urethane:
- Greater torque capability than NBR (1.5 times), provides less dampening effect, and operates in a smaller temperature range. Good resistance to oil and chemicals. Not recommended for cyclic or start/stop applications.
Hytrel®:
- Flexible elastomer designed for high torque and high temperature operations. Excellent resistance to oil and chemicals. Not recommended for cyclic or start/stop applications.
Bronze:
- Rigid, porous oil-impregnated metal insert exclusively for low speed (max 250 RPM) applications requiring high torque capabilities. Not affected by extreme temperatures, water, oil, or dirt.
