Bearings Units
MOUNTED BEARINGS AND HOUSINGS
Mounted bearings and housings with rolling bearings support a rotating shaft, which can be bolted on a machine frame or any other substurcture. There is no need to precisely machine a bearing housing in a surrounding casing. This makes these solutions cost-efficient and easy to use, while providing full rolling bearing performance.
BALL BEARING UNITS
Because of their versatility and cost-effectiveness, ball bearing units are typically used in many industrial applications.
Ball bearing units consist of an insert bearing mounted in a housing. An insert bearing is a deep groove ball bearing with a sphered (convex) outside surface and an extended inner ring that includes a mechanism to lock the unit onto the shaft. The housings have a correspondingly sphered but concave bore.
The SKF assortment offers a wide variety of units with different housing shapes and bearings using different locking methods. It includes units to ISO standards, North American standards, and Japanese Industrial Standards (JIS). Ball bearing units can accommodate moderate initial misalignment, but normally do not permit axial displacement.

Pillow Block Ball Bearing Units
Pillow Block Ball Bearing Units
SKF pillow (plummer) block ball bearing units consist of an insert bearing mounted in a housing, which can be bolted to a support surface. The SKF assortment includes units compliant with ISO standards, North American standards, or Japanese Industrial Standards (JIS). Within the SKF assortment, you can find units for nearly all requirements.
In addition, SKF Food Line ball bearing units provide hygienic and high-performance bearing unit solutions for the most demanding food and beverage environments.
Flanged Ball Bearing Units
Flanged Ball Bearing Units
SKF SKF flanged ball bearing units consist of an insert bearing mounted in a housing, which can be bolted to a machine wall or frame. The SKF assortment includes units compliant with ISO standards, North American standards, or Japanese Industrial Standards (JIS). Within the SKF assortment, you can find units for nearly all requirements regarding bolt patterns or locking on the shaft.
In addition, SKF Food Line ball bearing units provide hygienic and high-performance bearing unit solutions for the most demanding food and beverage environments.
Take-up Ball Bearing Units
Take-up Ball Bearing Units
SKF take-up ball bearing units consist of an insert bearing and a housing, and are compliant with ISO standards, North American standards, and Japanese Industrial Standards (JIS), as required by many industrial applications. In contrast, take-up units for the SKF Food Line are not compliant with these standards and are therefore considered as not standardized.
The SKF take-up ball bearing unit assortment comprises insert bearing series and designs, with the main differences between the take-up units being the housing design, the locking method onto the shaft, the sealing solution, and the options for end covers and back seals
Take-up units are typically mounted in take-up frames and are connected by an adjustment screw.
End Covers
End Covers
It is essential to protect bearing arrangements at the end of a shaft and to avoid the possibility of an accident caused by an exposed shaft end. To do this, most ball bearing units can accommodate specifically designed end covers.
Rubber Seating Rings
Rubber Seating Rings
NBR rubber seating rings “cushion” insert bearings in pressed steel pillow block housings. This helps dampen vibration and noise, and enables these bearings to be displaced slightly in their housings so that minor shaft expansion or misalignment can be accommmodated.
Units For Agricultural Applications
Units For Agricultural Applications
High availability of machinery is crucial to meet productivity requirements. The service life of SKF Agri Hubs can be multiple times longer than a traditional bearing.
SKF Food Line Ball Bearing Units
