SNK / SNH Series

The SNK/SNH series is the most popular housing form capable of accepting self -aligning ball bearings as well as spherical roller bearings. Shaft diameters from 20-140mm and a range of sealing options.

Plummer/Pillow block housings in grey cast iron are a common and simple way to support bearings in industrial machines.

The SNH/ SNK 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.

To ensure adequate lubrication in service consider use of the GreaseMax lubrication system.

Smaller bearings are usually fitted and set by tightening the locking nut by a set arc of movement. Larger bearings should be set to the correct radial internal clearance.

NBC Technical would be happy to advise on all aspects of selection, fitting and ongoing maintenance if required.
