Finer Power jaw Coupling Hub Half, L190

Hub Half are halves for jaw couplings, taper lock, in sizes L100 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 has a tapered bore that takes a taper lock bush. The bush is machined to your shaft size and keyway, so the half needs no boring. Bushes are sold separately.

Choosing the right option

Choose the size from the torque and the shaft size, and apply a service factor for the type of machine. 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.

Bushes are on Metric Taper Lock Bushes, Cast Iron and Imperial Taper Lock Bushes, Cast Iron. The flange half is Jaw Coupling, Half Flange Taperlock.

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.
