BRS Full Complement Needle Roller Bearings
Full complement needle bearings have a through hardened outer ring
which permitshigh static and dynamic load capacities and an ability to withstand
overloading,shocks and vibration. They are particularly suitable for operations
involving oscillatingmotion but may not accept high speed conditions where good
alignment is necessary.

BRS Bearing Heavy-duty Needle Roller Bearings
A heavy duty needle roller bearing is composed of a machined and
ground channel-shapedouter ring, a high-strength cage and a complement of needle
rollers. For ease ofrelubrication, outer ring with a lubrication groove and hole is
available. According tothe shaft surface condition, this kind of bearing can be used with
or without an innerring.
Sizes: Metric: 80 mm - 175 mm bore (3.1496 in. - 6.88976 in.).
1. Small radial cross section, space saving.
2. High load capacity and shock resistance provided by thick outer
Benefits: Optimal speed and lubrication-retention capability.
