Needle Roller Bearings - Thin Shell Type, Bore Sizes 3 Mm To 60 Mm | Lightweight, High Load Capacity, High-speed Rotation

Needle Roller Bearings

Shell type Needle Roller bearings are light-weight but are rates for heavy loads. They employ a Shell type outer ring made of thin special-steel plate which is accurately drawn, carburized and quenched, thus providing the minimum sectional height of the needle roller bearings. The caged type has a structure in which the needle rollers are accurately guided by the cage and thrust rings. It is useful for applications at high-speed rotations.

Available in Sizes From Bore size: 3 mm to 60 mm
Inches Bore size: 3.969 (5/32") to 69.85 (2 3/4")
Series mm: TLA (HK), TA (HMK), YT (FJ) (full complement)
Inches: BA (SCE), BHA (SCH), YB (full complement)

(b) Machine Type Needle Roller Bearings

Machined Type Needle Roller Bearings are bearings with a small sectional height and large load rating. The outer ring has high rigidity and can easily be used even for light alloy housings. These bearings are available in metric and inch series, both of which have the caged type and full complement type. It is therefore possible to select suitable bearing for use under various conditions , Such as heavy load, and high speed or low speed rotations. In addition there are bearings without and with inner rings , They are also available with side sealing to protect from dust and other factors.

Available in Bore Size from: 5 mm to 490 mm
Inches Bore Size: 15.875 (5/8") to 101.6(4")
Series mm: NK, RNA (without Inner Ring) NKI , NA (with Inner ring)
