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.

Series Flanged Housings
The I-1200 series are designed to accommodate
self-aligning ball bearings with extended inner rings, it can be used in
conjunction with ground shafting or bright drawn bar. As the outer ring is
axially located in the housing, axial movement is allowed by slotting the shaft
under the inner ring grub screws.
The 7225 series are designed to accommodate 12 series and
22 series self-aligning ball bearings as well as 222 series spherical roller
bearings with taper bore that mounted on adapter sleeves. Triangular housings
offer sizes 25~60mm; square housings offer sizes 65~100mm. The housing has
style A for shaft end design and style B for through shaft design.
SD Series
The SD series are available for large size bearings from
150mm bore. The basic dimensions are SD3000 and SD3100 series, and normally are
made of cast iron, but spheroidal graphite cast iron and steel housings can be
made to order.
The 7225 series are designed to accommodate 12 series and
