Pillow Blocks Bearing

Pillow blocks bearings are actually the pillow blocks fitted internally with bearings so there is no need to buy extra bearing for the same. Pillow blocks bearings take lesser load as compare to other bearings in the industry. Although pillow block bearings are also known as plummer blocks but there is some difference between the two as later is used in the industry that works on higher load and works in corrosive environment. Pillow block bearing works in very clean environment.

From inside pillow blocks bearings are quiet similar to deep grove ball bearings. But basically both these types of bearings work in similar manner allowing the outer ring to remain stable while the inner ring rotates.

The housing of pillow blocks bearings are of two types:

In split housing there are two piece of housing consisting of a cap and base. The cap and base can be separated. But in case of unsplit housing there is a single piece of housing. Housing in both the cases is generally made from grey cast iron.

Advantages of Pillow Blocks Bearings
Pillow block bearing eliminates the need of regular lubrication and maintenance because it contains the self lubricating cartridges. These cartridges presses into the ends of pillow block bearings to give lubrication.

 

Pillow block bearing can align themselves. So any alignment error or flexing of the shaft can be compensated by the self aligning property of pillow block bearings.

Also these can be very easily mounted and dismounted because of their compact structure.

Pillow block bearings come in different series and thus have wide range of applications. Various machineries, such as agricultural machinery.

They are widely used in various machineries, especially in agricultural, metallurgical, textile and mining machinery use the pillow blocks bearings.

Pillow Block Bearing Care
First of all read the pillow blocks bearings manufacturer's detail carefully and follow all the instruction and follow the care needs.

 

Read if any special grease is recommended in the manual. If so then use that same grease to give bearing a life. Along with this also know th amount of grease required.
