Needle Roller Bearings Roller bearings: bolt-type needle roller bearings (KR, KRV, KR.PP, NUKR etc.) bearing needle roller bearings (NATR, NATV, NUTR, NA22, etc.) are thick-walled outer ring, with high-temperature high-nitrogen quenching , high-precision roller separation of the outer ring by the high rigidity of the wall to guide the use of linear contact wheel can rotate in the roll along easily and can withstand the tremendous load. To remove the stress, the outer wheel support the use of Globoidal design, curves have with single wheel, dual-ring, non-ring, sealing ring with a variety of model specifications. Grease storage ring with a large space, they provide long-term lithium grease lubrication, and extended lubrication intervals. Sealing material for acrylonitrile-butadiene rubber, or with skeleton ST12, its operating temperature range of -30 ° C to +100 ° C or -30 ° C to +180 ° C. Density curve of the wheel-mounted can withstand extremely heavy loads and high-performance operation.

RSTO	The outer ring without ribs, roller bearings without inner ring
STO	No outer wall, the inner wheel bearing
RNA22...2RS	Double-sealed roller bearings without inner ring
NA22...2RS	Double-sealed, the inner wheel bearing
NATR NATR...PP	Ping ring axial roller bearing guide
NATV NATV...PP	Ping ring axial roller bearing guided, full needle
NUTR	Ball bearing roller guide, full roller-type
CRY	British style flat ring axial roller bearing guide

Bolt-type needle roller bearings (KR, KRV, KR.PP, NUKR etc.)

Curve of the wheel (also known as bearing bolts) KR Series, KRV series, NUKR series bolt-type needle roller bearings by the axle bolt G20CrMo after HVI ≥ 664, effective from fine 1.3mm hardened layer, and then by the group as a roller rolling Road bolts and a combination of thick-walled outer ring. Shoulder bolt axis and the pressure in the bolt face on the composition of the outer ring along the two sides of the direction of the guide surface. When the curve of the wheel in the flat raceway or cam plate on the sport, as a result of elastic deformation of the outer ring, the inner wheel to increase stress. Applies to such work is therefore under the curve of the rated load wheel select a column: (The following is a detailed description)
