Plummer Blocks Manufacturers by MBP-Bearings

We have started production of Plummer Blocks & Sleeves and dared to maintain a good quality at reasonable price range when the market was guided by low price level with worst quality product & some time the user had to us the sub-standard product unwillingly because the quality product was out of his budget. We had tried for a middle path. So that the customers can get quality product within their budget.

It is the common belief that a bearing housing has only supporting role to hold the bearing & to support its non-rotating outer ring. This is only one part of the fact.

The life of the bearing depends upon the proper selection of the block & its accuracy to the tolerance.

 

Main features of MBP Bearing Block are

1. Made of 20 grade cast iron.
2. Free from Blow Holes
3. 90% carbon matching with bearing
4. Prefect level of the foot & accurate center height
5. Attractive outer finish
6. Available in the steel casting & outer grades of cast iron as par specification
7. Made as per international standards for easy exchangeability

How to Preload Ball Bearings

In the case of ball bearings, preload is often a misunderstood concept and overlooked by designers and bearing users alike.

One of the final steps in the bearing manufacturing process is the assembly of the individual bearing components: the outer ring, inner ring, balls and retainer (or ball separator). When the bearings are assembled, it is necessary to have a controlled amount of internal clearance, or looseness between the rings and balls. This is referred to as radial play in most bearing catalogs.

In certain applications, this internal clearance must be removed for a pair of bearings to operate properly. The application of an axial load across a pair of bearings – for the purpose of removing free internal clearances – is called preload.

Benefits of preloading ball bearings include:

- Rotational accuracy and precise shaft positioning
- Elimination or reduction of ball skidding
- Control and reduction of axial and radial deflection under applied load
- Noise reduction
- Load sharing between bearings

Preload is critical in most high-precision and high-speed applications, particularly where rotational and positional accuracy is required.

 If, under operating conditions, a bearing has radial play this means that one bearing race can be moved radially and axially relative to the other. With rotation, this looseness translates into wobble or non-repetitive runout. This motion is unacceptable in applications such as machine tool spindles, electric motors, optical encoders, flow meters, and high-speed hand tools.

The application of axial preload forces the balls into contact with raceways, establishing a contact angle which causes the ball set to rotate in a uniform circumferential plane.
