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
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.
Roller Bearing Units
SKF roller bearing units (mounted bearing units) are robust, ready-to-mount bearing units that are assembled, lubricated and sealed at the factory for maximum service life.
The assortment includes bearing units with a pillow (plummer) block housing, including a relubrication-free variant, and units with a flanged housing, each optimized to accommodate different operating conditions. All bearing units are available as locating (held) or non-locating (free) units.
