SKF SNL Pillow Block Housing, SNL 520-617 90

SNL pillow block housings, series 5 and 6. The two-part SNL housings made of cast iron GG20 are designed using a modular system. This allows for a flexible choice of bearing, seal, and lubrication method. By combining the housings with various standard seals, a wide range of housing variants can be created, covering the majority of requirements for pillow block housings for shafts with diameters from 20 to 160 mm. They come standard with two elongated foot screw holes, allowing for subsequent alignment of the housing.

SNL pillow block housings are intended for the installation of spherical roller bearings or spherical plain bearings, which can be mounted on smooth shafts using locking sleeves. Fixed bearings can be achieved by inserting two identical fixed rings on either side of the bearing. This ensures a central bearing seat for fixed bearings. Suitable seals from the TSN series, end covers, or fixed rings must be ordered separately. Compatible with spherical roller bearings of series 12, 13, 22, 23 and spherical plain bearings of series 222 and 223.
