Split Plummer Block Housing with Self-aligning Ball Bearing

Views: 20     Author: Site Editor     Publish Time: 2021-08-24      Origin: Site

Plummer block housing is usually made of grey cast and spheroical graphite cast iron ,it have many different design just like SNL Series,SNLD series,SD Series,SDD series, SN Series, SNN Series, SNV, SNC, SNU Series, all of these plummer block housing are all can be working together with spherical roller bearings, which are designed on a building block principle, this enable more possibilities when it comes to selecting the bearing designs, locating rings, shaft, seals and the type of lubrication.

Plummer block housing is easy to installation and pre-assembled shafts can be mounted in them,split plummer block are not only working with spherical roller bearings, but also self-aligning ball bearings, Carb toroidal roller bearing, the housings can accommodate bearing in the 02, 03, 22, 23 30, 31, 32, 39, 40 and 41 ISO dimension series, several designs are available making the use of tailored housings unnecessary and thus enabling cost-effective bearing arrangements to be made.

Self-aligning ball bearing have cylindrical bore and tapered bore design, the cages have pressed steel and Phenolic resin etc. Its characteristic is that the raceway of the outer ring is spherical and has self-aligning properties. so it can compensate for misalignment and shaft deflection errors, However, the relative inclination of the inner and outer rings must not exceed 3 degrees.


 Self-aligning ball bearings manufacturer


Self-aligning ball bearings have two rows of balls with a common sphered raceway in the outer ring. This gives the bearings their self-aligning property, permitting angular misalignment of the shaft relative to the housing. They are therefore particularly suitable for applications where misalignment can arise from errors in mounting or from shaft deflection. In addition, non-sealed self-aligning ball bearings have the lowest friction of any bearing type.

Bearing sizes having the E suffix have higher load ratings than the original standard design because of improvements in internal construction. They are supplied with a glass fiber reinforced, 6.6 polyamide cage as standard. Machined brass or pressed steel cages are supplied on other sizes.

Basic Design Self-aligning ball bearings of the basic design are available with both a cylindrical bore and a tapered bore with a 1:12 taper. Tapered bore bearings are furnished with adapter sleeves, including nut and lock washer, with which the bearings can be secured to smooth or stepped shafts. They are identified by suffix letter K. Sealed Bearings Self-aligning bearings with cylindrical and tapered bores are available with contact seals on both sides, identified by the suffix 2RS1. The seals are made of oil and wear resistant synthetic rubber reinforced by a steel insert. The operating temperature range for the seals, with a suitable grease, is -40˚C to 120˚C (-40˚F to 248˚F). Sealed bearings are supplied with a lithium base grease suitable for an operating temperature range of -30˚C to 110˚C (-22˚F to 230˚F). Sealed Self-aligning ball bearings bearings with a tapered bore require a special adapter sleeve and lock washer identified by the suffix letter C. The lock washers have a circular beading on the side facing the bearing to prevent interference with the seal.

EASIER can supply different kinds of Self-Aligning Ball Bearings

Sealed Self-aligning Ball Bearings Extended Inner Ring

Plummer block bearing housing

Plummer block housing working with Self-Aligning Ball Bearings can achieve maximum service life with less need for maintenance, it is reduce the cost of maintenance,and also the design of plummer block housing with Self-Aligning Ball Bearings are easy alignment and handling during installation. so the plummer block housing with Self-Aligning Ball Bearings are widely used in the applications like:


- Material handling

- Handling systems

- Mining and construction

- Fluid machinery

- Metallurgical

- Pulp and paper


So split plummer block housing can meet their demand for demands as follows:


- Long service life

- Robust design

- Long relubrication intervals

- Ready for relubrication

- Condition monitoring facilities

- Avoid risk of mixed caps

- Fast and easy mounting and dismounting


Split plummer block housing with  Self-Aligning Ball Bearings sometime need more support when it working,adapter sleeves, cylindrical seats on stepped shafts, Standard seals, Labyrinth seals, Special seals, End covers, Locating rings, Lubrication,


Some suffix of Split plummer block housing


– Housing for a bearing on an adapter sleeve and a straight shaft

– G Housing for a bearing with a cylindrical bore and for a stepped shaft

– L Housing for a non-locating bearing arrangement

– F Housing for a locating bearing arrangement

– TURT Housing prepared for oil lubrication (spherical roller bearing) with seals

– TURA Housing prepared for oil lubrication (CARB toroidal roller bearing) with seals

– TURP Housing with a special seal for large axial movement and circulating oil lubrication

– V Housing with grease escape holes in the base

– T A drilled and tapped hole 1/8-27 NPSF at one side of the cap (opposite to the lock nut) to take a grease fitting AH 1/8-27 PTF

– TD A drilled and tapped hole 1/8-27 NPSF on both sides of the cap to take a grease fitting AH 1/8-27 PTF

For relubrication of the seals; two fittings supplied with the housing SN Housing with a drilled and tapped hole for a sensor, More information about Splummer block housing,EASIER will talk more in next coming days. If urgent need about Plummer block housing, please contact whatsapp: 0086-13280450757 or E-mail: sales@xrbearing.com
