L090 Jaw Coupling Hub 16 mm Bore

This metric jaw coupling hub fits a 16 mm shaft with a standard keyway and set-screw locking. It is intended for maintenance teams and OEM builders who need a direct replacement hub for L090 series couplings in light industrial drives.

Upgrading from worn L090 hubs

Replace an existing L090 hub when the bore or keyway shows wear, or when switching spider materials to match new torque requirements. The hub supports Buna-N, Urethane and Hytrel centre elements rated at 0.23 hp, 0.35 hp and 0.64 hp respectively at 100 RPM.

Check shaft diameter and keyway

Verify the driven shaft measures 16 mm with a 5 mm keyway width and 2.3 mm keyway depth before ordering. Confirm the coupling can operate within the 9 000 RPM maximum speed and that the 54 mm outside diameter clears adjacent components.

Questions about this item

What shaft diameter and keyway dimensions does the 16 mm bore hub accept?

How is the hub secured to the shaft, and what step is often missed?

Two set screws lock the hub; the common mistake is not tightening both screws to the recommended torque after aligning the key in the keyway.

Compatible replacement spiders are Lovejoy part numbers L090H for Hytrel, L090N for Buna-N and L090U for Urethane.
