Spacer Hub for 6SC Couplings

This cast-iron spacer hub fits TB Wood's Sure-Flex coupling size 6 and accepts a 1-3/8 inch round keyed bore. It is rated for 6,000 RPM maximum speed and 585 in-lb maximum torque. The hub suits compressors, conveyors, motors and pumps requiring a spacer configuration.

Replaces Worn Spacer Hubs in Size 6 Assemblies

Install this hub when the existing spacer hub shows bore wear beyond the +0.0005 to +0.0015 inch tolerance or when coupling vibration indicates hub damage. The jump is worth it if the current hub cannot maintain alignment at the rated 6,000 RPM limit.

Verify Bore, Keyway and Speed Before Ordering

Confirm the shaft measures 1-3/8 inch diameter with a standard keyway matching the round keyed bore type. Ensure the application does not exceed 6,000 RPM or 585 in-lb torque. Check that the 2-1/2 inch outside diameter clears adjacent components.

Questions about this item

What shaft diameter does the 1-3/8" bore of the 6SC spacer hub accept?

The round keyed bore measures 1 3/8 in with a tolerance of +0.0005 in / +0.0015 in for a secure shaft fit.

How do you install the spacer hub on a keyed shaft and what step is often missed?

Slide the hub onto the shaft, align the keyway with the shaft key, then tighten the set screw over the key; skipping the key alignment causes slippage.

What wear items on the 6SC spacer hub will need replacement over time?

The cast iron hub and keyway interface handle up to 585 in-lb torque at 6000 RPM; inspect the key and keyway for wear during scheduled maintenance.
