Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.
We supplies needle roller bearings in different designs and a wide range of sizes, which are appropriate for different applications. In addition to customized designs, they comprise the following types and components:
1. Needle roller and cage assemblies
2. Needle roller bearings with machined rings with flanges
3. Alignment needle roller bearings
4. Inner rings for needle roller bearings
The bearings we supply have the following specifications:
1)Material: Gcr15, Gcr15SiMn
2)Cage Material: Brass, steel
3)Quality standard: ISO9001
4)Noise standard: Z1, Z2, Z3, Z4
5)Vibration standard: V1, V2, V3
6)Precision standard: ABEC-1, ABEC-3, ABEC-5
7)Shield type: Z, ZZ, RS, 2RS, 2RS1, NPP, KDD, P, PP, N, NR
8)Feature: High precision, long life, low noise
9)Application: Automotive, electric motors, construction machinery, transmission shafts, gear shafts and various kinds of professional machinery.
10)We can also produce bearings according to customers's drawings&samples
