Bearing Units Self-Align
August 6, 2010—The ready-to-mount bearing units from NKE consist of a bearing fitted in a cast or pressed housing for material handling systems, such as conveyors, as well as applications in the heavy and agricultural machinery and steel industries. The bearing unit's housings can be combined with a range of bearing inserts. The cast iron housings are resistant to deformation and can absorb moderate to high loads. The pressed sheet steel housing models are suited for applications with lower loads due their lower weight and simpler installation. The bearing inserts consist of single-row deep groove ball bearings that are sealed on both sides against moisture, splash water and dust. Various seal types are available for different applications. The bearings are secured to the shaft with set screws or eccentric locking collars, which simplifies the installation. The bearings are factory lubricated and most bearing-housing combinations can be re-lubricated during operation to extend service life. The special version SQ171 is coated for enhanced corrosion protection. The spherical design of the bearings' outer diameters and the housings' inner diameter enable the units to self-align, so any misalignments that occur during installation or operation are compensated. NKE's bearing units are interchangeable with products from leading manufacturers.
