L050 Jaw Coupling Half, 9 mm Bore with Keyway

Metric jaw coupling halves, bored and keyed, in L050 to L225. The jaw coupling is used across a large range of industries. It is highly resilient, it needs no lubrication, and it works in environments contaminated with oil, dirt, sand, moisture and grease. The rubber element sits between the jaws of the two hubs and absorbs shock loading, so there is no metal-to-metal contact.

Each half comes bored to the bore you choose, from 9 to 60 mm, with a keyway cut, so it is ready to fit. 76 size and bore combinations are listed. Each listing is one half, and the spider is sold separately.

Selecting and fitting

Choose the size from the torque and the shaft size, apply a service factor for the type of machine, and pick the bore that matches the shaft. Each coupling needs two halves and one spider. Spiders are on Jaw Coupling NBR Spider Element, Jaw Coupling Hytrel Spider Element and Jaw Coupling Polyurethane Spider Element.

Imperial bores are on Jaw Coupling, Bore & Standard Keyway - Imperial. Halves with a pilot bore, for boring to size, are on Jaw Coupling Half Pilot Bore.

Isolate the drive before working on the coupling. Align the two shafts as closely as you can before fitting the coupling, and check the alignment again once the coupling is fitted. Good alignment gives the longest life, whatever the coupling type.
