FYH Metric adapter sleeves, 110mm

FYH H3000 series is a metric adapter sleeve (also spelt adaptor sleeve) for mounting a tapered bore bearing on a plain shaft. Choose the size from the Bore (mm) drop-down. An adapter unit is made up of an adapter sleeve, a lock nut and a lock washer. The sleeve is slotted and fits a tapered bore bearing to a plain shaft. The bearing and the adapter are separate items, so order both.

Key specifications

Fitting and use

Shaft: check the shaft for bends, burrs and other flaws before fitting.

Fitting: slide the adapter sleeve onto the shaft at the bearing position; if it is too tight, open the slot with a screwdriver. Slide the bearing onto the sleeve, place a cylindrical reinforcing ring against the front face of the inner ring, and seat the sleeve by tapping lightly around its back. Fit the lock washer with its tab in the sleeve slot, then screw the lock nut on by hand with the tapered side facing the bearing.

Tightening: a lock nut that is too loose lets the sleeve slip, which wears the shaft and the bearing. A lock nut that is too tight expands the inner ring and reduces the internal clearance, which can cause overheating and early failure.

Choosing the right option

Choose by shaft diameter and by the sleeve number your bearing needs: the two must match.

The H3000 and H3100 series both cover several of the same shaft sizes, so check the series on the sleeve your bearing calls for. The other series is the H3100 series.
