BRS FULL COMPLEMENT NEEDLE ROLLER BEARINGS
Full complement needle bearings have a through hardened outer ring which permits

high static and dynamic load capacities and an ability to withstand overloading,

shocks and vibration. They are particularly suitable for operations involving oscillating

motion but may not accept high speed conditions where good alignment is necessary.

Product Range:

1. Heavy-duty Needle Roller Bearings

2. Track Rollers

3. Thrust Bearings

4. Combination Bearings

5. Drawn Cup Roller Clutches

BRS Bearing Heavy-duty Needle Roller Bearings
Heavy-duty needle roller bearings consist of a machined and ground channel-shaped

outer ring with a complement of needle rollers retained and guided by a cage. The

high-strength cage retains and guides the rollers. An optional lubrication groove and

hole in the outer ring facilitate relubrication.These bearings can be used with or

without a machined and ground inner ring, depending on the suitability of the shaft as

a raceway surface.

Sizes: Metric: 80 mm - 175 mm bore (3.1496 in. - 6.88976 in.).

Markets: Gear pumps, sheaves, automotive transmissions and two-cycle engines.

Features: Thick outer ring provides maximum load capacity and shock resistance

with a relatively small radial cross section.

Benefits: Optimum speed and lubrication-retention capability.
