Flat Cage Needle Roller Bearings
Product feature:
Needle bearings feature a smaller cross-section, higher load-carrying capacity, greater rigidity, and lower inertia forces that facilitate size and weight reductions in machinery. They're designed to withstand oscillation, perform under severe conditions, and interchange with sliding bearings. Diverse types of needle bearings are available in a wide variety of sizes and tolerances, for a multitude of applications.
Type and Series of needle roller bearing:
Radial Needle Roller and Cage Assemblies (5mm ~ 480mm) - K, KK, KS, KKS series
Entity Bushed Needle Roller Bearings (5mm ~ 500mm) - NK, NKI, NA, RNA series
Drawn Cup Needle Roller Bearings (8mm ~ 45mm) - HK, BK series
Plane Thrust Needle Roller Bearings (4mm ~ 200mm) - AXK., AS, LS series
Linear (Motion) Needle Roller Bearings (15mm ~ 50mm) - LNS series
Application:
Needle bearings are heavily used in engine components such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive vehicle typically has at least 8 needle bearings (4 in each U joint) and often more if it is particularly long, or operates on steep slopes.
