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