Plumer Block Housing

Plummer Block Housings

Split plummer block housings are designed for easy mounting and dismounting of pre-assembled shafts. The housings can be used with high-capacity spherical roller bearings or self-aligning ball bearings. They 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.

 

Various housing designations including SN, SNU, SNK or SNL series, SD 3000, SD 3100 & SAF housings are available suitable for parallel or tapered shaft applications.

SN/SNH Series

The SN/ SNH series (interchangeable with SNA, SNU, SNN, SNV and SNL housings from other manufacturers) is arguably the most common style and can accommodate metric shaft sizes from 20 -140mm and imperial shaft sizes from 1.3/16" - 3.7/16". A variety of sealing options is available. All housings are supplied with locating rings which may or may not be required in the application.

For even greater strength, spheroidal graphite cast iron and even cast steel housings are available to special order.
