32 mm Bore L100 Jaw Hub

The Lovejoy L100 jaw coupling hub fits a 32 mm round shaft with a 10 mm keyway and set-screw locking. Carbon-steel construction handles up to 7 000 rpm and accepts Buna-N, urethane or Hytrel centre elements. Straight-jaw profile suits general power-transmission drives.

General Machinery Shafts Only

This hub serves metric shafts needing a standard L100 connection in pumps, conveyors or gearboxes. Builders requiring a different bore size, clamp-style locking or a non-L100 element series must choose another hub.

32 mm Bore Decides Fit

The 32 mm bore diameter with 10 mm keyway width and 3.3 mm keyway depth is the single dimension that determines whether this hub matches your shaft. Verify the shaft before ordering.

Questions about this item

How much heat or noise does the L100 hub generate when running continuously at 7,000 RPM?

The hub itself has no motor or bearings, so it produces no measurable heat or noise; any temperature rise comes from the driven equipment and the spider element.

What shaft and spider must I already have to install this 32 mm bore hub with 10 mm keyway?

You need a 32 mm diameter shaft with a 3.3 mm deep keyway and a compatible L100 spider — Buna-N, Urethane or Hytrel — plus a second L100 hub for the opposing shaft.

Will this carbon-steel L100 hub work with an older cast-iron L100 hub on the same spider?

Yes, the straight jaw profile and L100 size match any L100 hub regardless of material, so it pairs with legacy cast-iron hubs using the same spider.
