SNL 500 Series Split Plummer Block Housings

The Plummer Block, as known as (Split) Bearing Housing, which is an assembly comprising of a self-aligning ball bearing or spherical roller bearing placed in bearing boxes of various shapes, has a large load capacity and is easy to handle, therefore it is widely used in general industrial machinery such as conveyors.

Plummer Block Housings are manufactured from high-strength cast iron as standard but are also available in cast steel or spheroidal graphite cast iron. The housings have a re-lubrication facility and can be used with either oil or grease lubrication.

The SNL Plummer (Pillow) Block Housings are the most popular SKF bearing housings on the market, developed to be the first choice for design, quality and economy. They enable built-in bearings to achieve maximum service life with less maintenance requirements. Different bearing housing variants and seal designs are available, virtually eliminating the need for custom housings and allowing cost-effective bearing configurations to be manufactured.

SNL housings are made of grey cast iron. For applications where extra strength is needed, SNL housings are also available in spheroidal graphite cast iron. Housings made of spheroidal graphite cast iron are available from size 510-608 and are supplied with a solid base (no holes for attachment bolts) as standard. From size 511-608 the housings can be supplied with four oblong holes cast in the base. All bearing housings made of spheroidal graphite cast iron can be supplied with two drilled holes for attachment bolts.
