Properties & Qualities of a Bearing

Written by

Bearing manufacturer in India is successfully made of superior high quality metal which is absolutely 100% authentic in style and has gone through a strong and roughs multiple check zones. Offering a wide range of products in various sizes, specifications and in different grades, the bearing manufacturer in India produces products that are highly demanded across India as it has a smart engineering design, with tough construction with anti-corrosive nature and a fine finish with long-lasting capacity. There is 1000+ big and small bearing manufacturer in India currently.


The selection of the type of bearing metal mainly depends on the conditions under which the bearing is mainly put into, such as the temperature, bearing pressure, the type of lubrication used, rubbing speed etc. Also, the bearing must possess some of the general qualities as well; some of the desiring characteristics are as follows:


  • The bearing should have the ability to withstand the bearing pressure.
  • The bearing should have sufficient endurance strength to avoid the failure due to the fluctuating load.
  • The bearing material should not be completely a damaged journal material because of the sticking and welding.
  • The bearing material should possess an embed ability characteristics avoiding the damaging journal because of the dirt and dust particles.
  • The bearing material should be elastic enough to restore its original shape upon removal of load after some distortion.
  • The bearing should be water resistant.
  • Many types of liquids, cutting fluids and lubricating oils may get in contact with the bearing. So it should have good noncorrosive properties.
  • Wettability – it should have an affinity towards the lubricating oil so that it can adhere, spread and make a lubricating film over the bearing surface.
  • The bearing material should also possess a low coefficient of friction.
  • The bearing can be easily manufactured if it has the right casting qualities.
  • After the casting, the shrinkage condition should also be minimum of the bearing.
  • The bearing should be operated at a maximum rubbing speed with a suitable lubrication.
  • The bearing material should be exposed to heat, therefore it should have a high thermal conductivity and a high melting point, and however it should also have a low thermal expansion.
  • The material used for bearing should be economical. Low cost and easily available material.


When the surfaces of the bearing are separated by a fluid film, the bearing materials do not have any effect on its operation so long as the parts have sufficient strength to withstand the imposed loads and sufficient rigidity to maintain alignment.
