shaft support pillow block bearings UCP326 & UCP326 insert bearings stainless
Descriptions of UCP326 bearings 

A pillow block, also known as a plummer block or bearing housing, is a pedestal used to provide support for a rotating shaft with the help of compatible bearings & various accessories. Housing material for a pillow block is typically made of cast iron or cast steel.

Pillow blocks are usually referred to the housings which have a bearing fitted into them & thus the user need not purchase the bearings separately. Pillow blocks are usually mounted in cleaner environments & generally are meant for lesser loads of general industry. These differ from "plummer blocks" which are bearing housings supplied without any bearings & are usually meant for higher load ratings & corrosive industrial environments. However the terms pillow-block & plummer-block are used interchangeably in certain parts of the world.

The fundamental application of both types is the same which is to primarily mount bearings safely enabling their outer ring to be stationary while allowing rotation of the inner ring. The housing is bolted to a foundation through the holes in the base. Bearing housings are either split type or unsplit type. Split type housings are usually two piece housings where the cap and base can be detached, while certain series are one single piece housings. Various seals are provided to prevent dust and other contaminants from entering the housing. Thus the housing provides a clean environment for the expensive bearings to freely rotate, hence increasing their performance and duty cycle.

Bearing housings are usually made of grey cast iron. However various grades of metals can be used to manufacture the same.

The pillow block ball bearing is composed of a single row deep groove ball bearings with seals at both sides and spherical outside surface and a housing, suitable for simple support, widely used in various of mechanical equipment, especially for agricultural, metallurgical, textile, and printing machinery.

 

Details of UCP326 bearings

 

This is the most common type of mounted ball unit. The rib at the bottom of the housing mounting section provides for a robust unit that can withstand great loads from any direction. Mounted units with cast steel housings are also available in this series, and are used for applications with severe loading and shock load conditions. Tapered-bore style units are offered individually and adapters are sold separately.

Applications of UCP326 bearings

Insert ball bearing unit is consisted of a double sealed, single row bearing and one of housings(cast iron housing, stamping steel housing, stainless steel housing, engineering plastic housing, nodular cast iron housing, nickel plating housing, zinc alloy housing, etc). They are widely used inagricultural machinery, construction machinery, textile machinery, foodstuff machinery and conveying devices, etc.

 

 

Special Note on Location of Bearings in Pillow Blocks

 

If the bearing is to be held (located), fixing rings are inserted

 

between the side faces of the outer ring and the housing

shoulders. If an adapter sleeve is used to secure the bearing

to the shaft and only one fixing ring is required, it should be

placed on the same side of the bearing as the locknut. The

bearing is then displaced from its central position in the housing by a distance equal to half the fixing ring width.

1 ring - on the same side as the sleeve nut

2 rings - one on each side of the bearing

3 rings - two on the same side as the sleeve nut

4 rings - two on each side of the bearing

The method of bearing installation:

(1) cleaning bearings and related components;

 

(2) check the connected components of size and finishing machining;
(3) installation
(4) inspection of the bearings after installed;
(5) the supply of lubricant. 

 

 

Working principle :

Pillow blocks, the most commonly used type of mounted units, are designed to provide shaft support

where the mounting surface is parallel to the shaft axis. The bolt holes are usually slotted for adjustment during mounting.

Pillow blocks are supplied in a variety of configurations. Pressed steel pillow block bearings are also available for lightduty 

applications.

It is widely used in food machine, pharmaceutical machinery, conveying systems, photo & film 

processing machinery, spin machine,dying & printing machinery and so on.
