ASNH end covers close off split bearing housings. Once mounted, they hold the bearing in its axial position and keep dust, moisture and other contaminants away from the raceway. They belong to the SKF accessory range we supply, and the correct one is chosen according to the housing and shaft diameter. To replace a cover or complete a housing, send the part number and we will quote it.

The ASNH prefix identifies a family of end covers for split housings. The number after it sets the size: ASNH 216, ASNH 217 and ASNH 218 fit housings for different shaft sizes, while ASNH 505, ASNH 506-605, ASNH 507-606, ASNH 508-607 and ASNH 509 serve other housing combinations. A hyphenated code such as 506-605 means the same cover works on more than one housing size. Always cross-check the cover number against the housing you have installed.

These covers suit equipment where bearings run in dirty or damp conditions: conveyors, mills, mixers, pumps, fans and plant machinery. They are common in food processing, cement, mining, chemical and aggregate operations, where split housings are preferred for easy mounting and maintenance. By keeping dust and water out of the raceway, the ASNH cover helps the bearing reach a longer service life.

Before mounting, confirm the cover matches the housing and shaft diameter. Clean the housing surface thoroughly, check that the cover seats without forcing, and tighten the screws or bolts as applicable. Under high vibration, inspect the fit at regular intervals. Lubricate the bearing before closing the cover; adding sealing where the housing allows improves grease retention and contaminant exclusion.

SKF ASNH covers can be interchanged with covers from other makers that follow the same dimensional designation, but not every brand uses the same code. Compare the original part number with the housing number and check compatibility before replacing. We supply SKF and can help you match the cover to your housing so it does not create play or leaks.

If you have the cover or housing part number, send it to us and we will quote it. We can also help you identify the right cover if you provide the shaft diameter and housing type. For technical advice on your application, write to us and we will review it with you.
