Specifications:
high quality with reasonable price
High carrying capacity
high precision
Material: Chrome Steel , Carbon steel, Stainless steel
Certificate: ISO 9001:2000
Type: N, NU, NJ, NJP
Service: OEM
Seals Type: RS, 2RS, R2, Z, 2Z, 2RZ etc
Features: It is the separable bearing with low friction and high limit speed.
The double row cylindrical roller bearing has the advantages of compact structure high rigidity and load capacity etc.
Application:Large and medium-sized motor, locomotives, spindle, internal combustion engines and generators, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery
Cylindrical roller bearing features:
1. Roller and groove for line contact or repair referral contact, radial load capacity, is designed to withstand heavy load and impact load.
2. Small friction coefficient, suitable for high speed, limit rotational speed close to deep groove ball bearing.
3. N-type and NU type can axial movement and can adapt caused by thermal expansion or installation error and shell the shaft of relative location changes, can make free use of the bearing. 4. The hole of shaft or block the demand is higher, bearing processing after installation relative skewed to outer ring axis and kept under strict control, lest cause contact stress concentration.
5. Inner circle or their cups are separable, convenient in installation and removal.
