Bearing and Housing Unit: SKF bearing units typically consist of a bearing, seal, lubricant and shaft locking mechanism. The units are preassembled and adjusted at the factory. These ready to mount units are available with either ball or roller bearings. In addition to standard all steel units, SKF has more focused standard products – which target a particular industry – like the food, beverage and pharmaceutical industries where, for example, special materials, lubricants, seals and housings are needed.
Y-BEARING HOUSING UNIT (ball bearing units)
Conventional SKF ball bearing units are referred to as Y-bearing units. These units consist of:
- Y-bearing (insert bearing) which is based on a single row deep groove ball bearing with a sphered (convex) outside surface and an extended inner ring
- Housing, which has a correspondingly sphered but concave bore
Y-bearing units can accommodate moderate initial misalignment, but normally do not permit axial displacement.
