Cylindrical Roller Bearing

Roller bearings, cylindrical roller cylindrical roller according to the heart of cylindrical roller is rolling bearings. Cylindrical roller bearing and rolling cylindrical roller bearing for line contact. Load capacity, the main radial load. Scroll to contractor, suitable for small raised edge friction spinning speed. According to the contractor may have raised edge, NU, floatation, NUP, N, NF, etc, and bearings NNU, double row bearing etc. NN The inner ring and outer bearing is separable structure. Inner circle or no raised edge of cylindrical roller bearing outer ring and that can move relative to the axis, so as the bearings use free. The outer ring and, one side, the other side is double raised edge of the rings have individual raised edge, cylindrical roller bearing can withstand a certain degree of axial load in one direction. General use stamping steel frame, or copper alloy and keep on making cars. But some using polyamide forming maintains. Cylindrical roller bearing features: 1. To roll with roller line contact or repairing referral contact, radial load capacity, applicable to withstand heavy load and impact load. 2 small friction coefficient, suitable for high speed limits, to deep groove ball bearings. 3 N and NU type can axial movement, can adapt the expansion or installation error caused by the relative position of the shaft and the shell, can make use of the supporting free. 4 for shaft or block hole machining the demand is higher, after installation invading.this bearing relative to strict control axis deflection, lest cause contact stress concentration. 5 ring in separable, convenient in installation and removal. Main purpose: large motor vehicles, motorcycles, spindle, internal-combustion engine, generator, gas turbines and reducer, rolling mill, the vibration and hoisting, etc.
