Bearings are mechanical parts designed to support machinery. Typically made of metals such as steel, our roller bearings can be designed to absorb shock, store energy and support a variety of applications. It comes in a variety of shapes and sizes and can be customized to meet the specific needs of your application.

What are Needle Roller Bearings?

Needle Roller Bearings are special roller bearings that use needle-like elongated cylindrical rollers. These bearings typically have rollers that are at least four times their diameter. As with all bearings, they are used to reduce friction on rolling surfaces.

Compared to ball bearings and regular roller bearings, needle bearings have a larger contact area with the race and can withstand greater loads. It is also thinner, which means less clearance is required between the axle and surrounding structures.

Features: Needle Roller Bearings

  • Low rolling friction: Needle bearings are lighter than steel, so these have less centrifugal force and less rolling friction. The contact ellipse is small due to the high elastic modulus.
  • Low sliding friction between ball and raceway: At high speeds, sliding friction dominates the total friction. One of the criteria for sliding friction is a low spin-roll ratio, exceeding 0.25 affects life.
  • ● The critical speed for minimum oil lubrication is significantly increased. In many cases, it can replace expensive oil jet lubrication.

Applications of Needle Roller Bearings

  • ● Machine tool spindle: Modern machining processes such as high-speed milling require new concepts in spindle bearings. The use of hybrid bearings has greatly improved performance. We have been successfully using spindles with hybrid bearings in our own production processes for many years.
  • ● Vacuum pump: Reliability of these bearings is of utmost importance as failure can be costly.
  • ● It is used in medical equipment such as X-ray tube storage. The Emergency bearings such as safety bearings for Magnetic Bearing Systems and Aerospace.
