Finer Power jaw Coupling Spacer, L190 - 140mm

These are spacer assemblies for jaw couplings, in sizes L100 to L225, in spacer lengths of 100, 140 and 180mm. 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.

A spacer extends the distance between the two shaft ends, which leaves room to remove a pump or a seal without moving the driver or the driven machine.

Where this product is used

• Pump drives where the pump needs to be removed without moving the motor
• Gearbox and conveyor drives with a gap between shafts
• Compressor and general machinery drives
• Drives with shock loading or minor misalignment

Features

• Spacer lengths of 100, 140 and 180mm
• Sizes L100 to L225, bores from 10 to 65mm
• Bore range, main dimensions and outside diameter for every size
• No lubrication needed, and suits oily and dirty environments
• Rubber element absorbs shock loading with no metal-to-metal contact

Key specifications

Sizes available

Choosing the right option

Choose the size from the torque and the shaft size, then the spacer length from the gap you need between the shaft ends. Bores and keyways are finished to suit the shaft. The spider is chosen separately: see Jaw Coupling NBR Spider Element, Jaw Coupling Hytrel Spider Element and Jaw Coupling Polyurethane Spider Element.

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.
