Bearing Units

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

The fundamental application of both types is the same which is to 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.

 


KOYO Bearings

A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.

Mitsuboshi Belts

A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel.

Oil-Seals

A Seal is a device that helps join systems or mechanisms together by preventing leakage.

Roller-Chain

is a way of transmitting mechanical power from one place to another.

Danzol Grease & Lubricants

Lubrication is simply the use of a material to improve the smoothness if movement of one surface over another

Sprockets

is a profiled wheel with teeth, cogs, or even sprockets that mesh with a chain, track or other perforated or indented material.

KSM Bearing-Units

A pillow block is a pedestal used to provide support for a rotating shaft with the help of compatible bearings & various accessories.

Fasteners

Strength of this fastener is derived from the compression of the plates, mounted above and below the belt, with high tensile strength bolts.
