We also offer a direct SKF replacement for the Lovejoy couplings. These are held in stock and can be despatched immediately

Straight-Jaw Couplings FAQs

What information do I need to specify a straight-jaw coupling?

To specify the correct straight-jaw coupling, we’ll typically need: shaft diameters and tolerances, required torque or kW and speed (rpm), shaft–shaft distance (if using a spacer), operating environment (temperature, chemicals, moisture), and any misalignment or shock loading. Our team can help you gather the key data and recommend a suitable coupling.

Are the hubs and inserts supplied together or separately?

Straight-jaw couplings are usually supplied as separate components: two hubs and one insert. On our website, these are often ordered individually so you can mix and match hub bores and insert materials to suit your application.
