NRB Needle Roller Bearing which have a high load carrying capacity, consist of outer ring made from through- hardened bearing steel. The cage guides the needles and retains them in the outer ring. The bearings may be used without an inner ring if the shaft journal serving as a raceway is of sufficient hardness and has the correct surface finish. To ensure that the full load capacity of these bearings is achieved, a hardness of 58-64 HRC is required.

• The basic construction of needle roller bearings is With integral end flanges on both sides, channel shaped outer rings
• With inserted end washer to provide axial retention of needles roller and cage assemblies
• Needle roller bearing with integral flanges
• The needle roller bearing has one piece, channel shaped outer ring of bearing quality steel heat treated to yield maximum load rating.
• The integral end flanges provide axial location for the needle rollers. The bores of the end flanges serve as piloting surfaces for cages.
• A steel cage provides inward retention for the needle rollers and the design assures roller stability and minimizes friction between the cage and the needle rollers. The cage has maximum strength consistent with the inherent high load ratings of needle roller bearings. The outer ring has a lubricating grove and a lubricating hole for more convenient lubrication of the bearing. However smaller sizes don’t have lubrication hole

A needle roller bearing is a type of rolling-element bearing that uses long, slender cylindrical rollers (known as needles) to reduce friction between moving parts. These bearings are designed to handle high radial loads with minimal space, making them ideal for applications where compactness and high load capacity are essential. Needle roller bearings are commonly used in automotive, industrial, and machinery sectors, including transmissions, engines, and pumps, due to their efficiency in reducing wear and enabling smooth rotation. They provide enhanced durability, performance, and cost-effectiveness in various mechanical systems.

A Tapered Roller Bearing is a type of rolling-element bearing that uses tapered cones to support both radial and axial loads. It consists of four key components: the inner race (also known as the cone), the outer race (the cup), the tapered rollers, and a cage to separate and guide the rollers. The rollers are tapered in shape, with their surfaces angled relative to the bearing's axis, allowing the bearing to handle forces from multiple directions.

The main feature of tapered roller bearings is their ability to bear heavy axial loads in addition to radial loads, which makes them highly effective in applications like automotive wheels, gearboxes, and industrial machinery where combined loads are common. The tapered geometry ensures a line contact between the rollers and races, providing high load-carrying capacity and improved performance under challenging operating conditions.

These bearings come in various designs, including single-row, double-row, and four-row configurations, each tailored to meet specific application requirements. When properly mounted and lubricated, tapered roller bearings offer long service life, reliability, and reduced maintenance needs, making them essential in high-demand applications.

NRB CRL 12 Cylindrical Roller Bearing offers its standard assortment of cylindrical roller bearings in a steel cage in the N, NF, NJ, NU and NUP types with an inner diameter from 20mm to 120mm in C2, C3, C4 and C5 clearances. Due to their cage design, these bearings can accpmodate heavy radial loads, rapid accelerations, and high speeds. We offer customized bearings in brass and polyamide cages for unique application requirements.
