What is A Needle Roller Bearing?

Needle roller bearings with thin and long rollers(roller length is 3-10 times of diameter, diameter is no larger than 5mm) So radial structure is impact. When the inner diameter and load capacity is same with other type of bearings, the outer diameter is min. Needle roller bearings are suit for radial installation when there is limitation of size of support structure. According to different applications, we can choose bearings without inner ring or needle roller and cage combination. For this situation, the surface of the shaft and the housing surface can be as direct the surface of rolling. To ensure the load capacity and rotation performance same as needle roller bearings with rings, the shaft and housing surface hardness, precision and quality should be same as the bearing ring’s surface. This type bearing can bear radial load.

Types of Needle Roller Bearings

1.Main structure

(1)Needle rollers and cage assembly K series.

Needle rollers and cage as a separate bearing unit, needle rollers are guided by cage precisely. This type of bearing without rings and with small radial section but load capacity is large is suit for the support structure with limiting radial installation space. The surface of shaft and housing can be direct as working surface for bearings. The surface hardness will be normally 58-64HRC, the depth of surface hardening is 0.6-1mm. The roughness Ra is 0.2µm.

(2)The outer ring has double ribs (or double locking rings) with inner ring NA series and NKI series.

This type of bearing can be installed separately by inner ring and outer ring(with locking ring, full sets needles and cage). The limiting speed is high. And there is single row and double rows series:
Single row series: NA48, NA 49, NA 69 series(d≤32mm) and NKI series
d≤7mm, the bearing will with locking ring 8mm≤d≤360mm the outer ring of bearing with double ribs.
Double rows series: d≥32mm NA 69 series

(3)Needle roller bearings without inner ring but with cage. RNA series, NK series, NA 0000 series

Single row series: RNA 48, RNA 49, RNA 69series (Adapt for 16mm≤Fw≤35mm) and NK series
Fw≤10mm the outer ring of the bearing with double locking ring. 12mm≤Fw≤390mm the outer ring of the bearing with double ribs.
Double rows series; RNA 69 series
This type bearing without inner ring that is suit for support structure of the radial install size limiting. The shaft surface matching with the bearing is directly as the rolling surface. The limiting speed is high.
Hardness of this needle roller bearing without inner ring will be 58-64HRC surface hardening depth: 0.6-1mm. The roughness of rolling surface Ra is 0.2µm

(4)Stamping needle roller bearing without inner ring but with cage HK 0000 series and BK 0000 series

4-1) HK 0000 series The two side of the bearing ends are empty
4-2)BK 0000 series With one side of the bearing closed is suit for where there is no extension of the shaft and can bear small axial force, closed end is for sealing.
This type of bearings are consist of thin wall stamping outer ring, cage and full set needles, the cost is low, load capacity is large. They are used for structure where with limiting installation of radial. The shaft surface is as rolling surface with hardening.The hardness should no less than 60HRC while surface roughness Ra is 0.2µm

2.Material of needle roller bearing

Needles and rings with outer ring with double ribs normally use Gcr15. The hardness of needles and rings will be 61-65HRC
Outer ring of stamping needle roller bearings use quality no less 10# or 08# premium cold rolled steel roll after heat treatment, the surface hardness should no less than 664HV0.1.
Cage of needle roller bearing normally use premium low carbon steel to produce. And by requirements, it also can be made by alloy steel or engineering plastic

3.Tolerances of needle roller bearings

Tolerances of needle roller bearings normally will be 0 level.
Needles precision normally according to using requirements
Stamping needle roller bearing normally use G3 level needles.

4.Application of needle roller bearing

Needle roller bearings are widely used on following areas:

1.Automotive industry

Needle roller bearings are widely used in Engine, turbine, steering gear, wheel hub. They can work in high temperature, high pressure and high speed situation that can make the safety of cars.

2.Aerospace industry

Needle roller bearings are also play an important role in aerospace industry. They can adapt for high temperature, high pressure and high speed such bad circumstance. They can keep the safety of airplane or aircraft

3.Machine tool industry

Needle roller bearings can make sure the precision of machine tool process. They can bear rotation in high speed and high precision.

4.Electric power industry

Needle roller bearings are also an important role in electric power industry. They can keep electricity equipment safe and reliability with high temperature, high speed and high pressure.
