Jaw (Spider) Couplings
Spider jaw type (Spidex) couplings are characterized by high torque capacity, light weight and low mass moments of inertia.
Spider couplings are torsionally flexible and designed for positive torque transmission, and they are fail-safe. Operational vibrations and shocks are efficiently dampened and reduced, and two congruent coupling halves with concave claws on the inside are peripherally offset in relation to one another by half a pitch. They are designed to enable an involute spider to be located between them.
These couplings are capable of compensating for axial, radial and angular displacements of the shafts that are connected. The maximum torsion angle amounts to 5°, and they can be fitted, both horizontally and vertically.
These coupling are customized to each application for our customers, below are the options available to you.
Design Type: “A” Hub- Tapered Hub / “B” Hub- Straight Hub
Materials for Hubs: Powdered Metal, Aluminum, Steel, and Cast Iron
Sizes: from 14 - 180
Optional keyways and set screws available
Bores: Most available in solid, rough stock bore (dimple) or a minimum and maximum depending on your application.
Spider Material: Polyurethane
Spider Colors and Uses:
Yellow: 92 Shore- General and Hydraulic Applications
Red: 95/98 Shore- High Torque Requirements
Blue: 80 Shore- Good Dampening properties
Green: 64 Shore – High Humidity Environments
