Coupling and Bearing Guards
Shield couplings and bearings from dirt and debris while protecting fingers and tools from moving parts. Guards are electrically nonconductive, and resist chemicals, corrosion, and impact. They are OSHA compliant 29 CFR 1910.219 for rotating machinery. Guards come unassembled.

Shaft Coupling Covers
Extend the life of your rigid shaft couplings by blocking out dirt, water, lubricants, and other contaminants. These two-piece covers twist together to form a shell around the coupling. Viton® fluoroelastomer O-rings on the threads and around each shaft complete the seal. The outer surface is knurled for a good grip when tightening by hand. Covers are only for use with round, unkeyed shafts.

Shock-Absorbing Flexible Shaft Couplings
A strip of flexible spring steel wraps around the teeth of both hubs to absorb sharp, momentary load increases that can come from motor startups, emergency braking, or sudden impact with hard objects. When the shock load hits, the strip of spring steel (known as a grid) flexes to spread out the load. After the load passes, the grid straightens back out. They're commonly found in wire drawing and cutting machines, pulverizers, and mixers. Compared to spider couplings, jaw couplings, and other flexible shaft couplings, these handle higher torque while taking up less space. All have keyed bores to work with keyed shafts, which transmit higher torque with less slippage than round shafts.
A complete coupling consists of two hubs as well as a grid and cover assembly (all sold separately). The grid and cover assembly includes a spring steel grid, aluminum cover, rubber seals, and grease for lubrication. When ordering, please choose components that have the same manufacturer series number, otherwise the grid will not fit.

High-Torque Flexible Shaft Couplings
With a rugged roller-chain design, these couplings provide excellent torque and angular misalignment capacities. Lubrication is required. Fasten to your shaft by tightening the set screws, which bite into the shaft to hold it.
A complete coupling consists of two hubs and one roller chain (each component sold separately). Complete couplings meet ANSI B29.23M-1995.
Optional covers retain grease lubrication and provide protection from abrasion and corrosion.

External Grip Puller Safety Guards
Wrap these guards around grip pullers, presses, and other moving equipment to protect yourself from flying debris. The transparent plastic is tough enough to contain fast-moving parts without tearing, and won’t block your view of the machine. Hold these guards in place with straps—the squeeze-release buckles make them easy to install or remove.
