Needle bearings are a small cylindrical type of roller bearings which are used to prevent friction between moving surfaces which have low rotational speeds.

Needle Bearing

A needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers resembling needles. Ordinary roller bearings’ rollers are only slightly longer than their diameter, but needle bearings typically have rollers that are at least four times longer than their diameter.Like all bearings, they are used to reduce the friction of a rotating surface.

Compared to ball bearings and ordinary roller bearings, needle bearings have a greater surface area in contact with the races, so they can support a greater load. They are also thinner, so they require less clearance between the axle and the surrounding structure.

What’s special about it?

Rolling elements used are shaped like needles, hence the name. These steel needles, with round or flat tips, have a diameter less than or equal to 5 mm, and their length must be at least 3 times greater than their diameter.

It enables extremely compact assemblies and is the first choice bearing when looking for a good compromise between performance, size and weight.
A needle roller bearing is thus able to withstand 2 to 8 times more load than ball bearings or cylindrical roller bearings of the same shaft diameter, all this in a small space.

The bearing supports very heavy loads thanks to the contact surface developed by the needles which are mounted in a steel or moulded polyamide cage.

These bearings that combine robustness, precision, and endurance concern all industrial markets and are very much present especially in:

  • Automobiles,
  • Two-wheelers,
  • Portable tools (drills, chainsaws,…),
  • Construction machinery,
  • Pumps and motors.

For Which Use?

Depending on the sector of activity and the application, needle roller and cage assembly can be integrated between rings that stiffen the assembly and ensure the connection between the various mechanical parts.
Needle roller bearings are therefore available in many forms (cages, bushings, bearings with solid rings, combined bearings, needle thrust bearings, cam followers, etc.) to meet all the technical constraints of the industrial markets.

Our Needle Bearings

Our needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The modified roller/raceway profile prevents stress peaks to extend bearing service life.

We supplie needle roller bearings in many different designs, series and in a wide range of sizes, which makes them appropriate for a wide variety of operating conditions and applications.

Needle Bearing

Needle bearings are a small cylindrical type of roller bearings which are used to prevent friction between moving surfaces which have low rotational speeds. Needle roller bearings are usually used when space is at a premium as needle bearings are much more compact than ball bearings. 

In some cases needle bearings can be used without an inner race or outer race or either as the needle rollers in the bearings can operate alone.

For needle rollers to be effective, the hardness, accuracy and finish of the shaft needs to have exactly the same qualities as the bearing races.

Due to the small size of needle roller bearings and the high speeds they are able to rotate at, they are used in compact mechanisms such as gear boxes, for example in an average car the drive shaft will usually have eight or more needle bearings in it.
