Felstrom's H311 adapter sleeve ensures that conic bearings can be easily fitted onto or removed from a cylindrical shaft. We recommend that the adapter sleeve is replaced each time a bearing is fitted or removed. This prevents damage or contamination during fitting or removal and extends the lifespan of the bearing. Felstrom's H311 adapter sleeve can be used in combination with bearings of any brand. The H311 adapter sleeve is used for fitting and removing 50mm shafts (d1) and is suitable for 1311K, 2211K, 21311CK and 22211CK bearings.
Felstrom adapter sleeves are always supplied with associated lock nut and locking ring. Felstrom supplies all regular adapter and withdrawal sleeves in both metric (H series) and imperial sizes (HE , HA and HS series). Felstrom's adapter and withdrawal sleeves are characterised by a neat finish for the thread and running surface. All Felstrom products are packaged individually. Felstrom’s affordable adapter and withdrawal sleeves are now available here.
