Product Description

Curve rollers (also known as bolt bearing) KR Series, KRV series, NUKR series bolt type needle roller bearing is a G20CrMo bolt shaft through HVI ≥ 664, the effective hardened layer 1.3mm refined, then the group as a roller rolling Road bolts and a thick-walled outer ring combination. Bolt axis and the pressure in the shoulder bolt ring formed on the outer face along the direction of the two sides of the boot surface. When the curve in the flat wheel roller or cam plate movement, the elastic deformation of the outer ring and rollers to increase the internal stress. Therefore, this work applies to the rated load under the wheel, select a column curve: (The following is the detailed description) In addition to our large diameter can be custom CF, CRY, CYR, NCF series of roller bearings.
