Radial needle roller and cage assemblies have a steel cage that provides both inward and outward retention for the needle rollers. The sizes are ranging from 3 mm to 165 mm bore (0.1181 – 6.4961 inch).

A symbol of dependability and flexible engineering solutions, NBC Bearings is the brand of National Engineering Industries.

These bearings are available in a wide range of inch and metric sizes plus an array of design features including: integral seals, side flanges (or separate end washers), inner rings, oil holes and single or double cage sets (or full complement) or rollers

Metric inner rings are available in 5 mm bore (0.1969 inch) to 180 mm (7.0866 inch) outer diameter and are made from bearing-quality steel and their diameter and bore are precision-ground. They function as the inner raceway for a needle roller bearing by providing a surface that meets all shaft raceway design requirements (hardness, surface finish, roundness etc.)

Combined bearings consist of a radial bearing (needle roller bearing) and a thrust bearing (needle or cylindrical roller bearing). They are available in 5.000 mm -70.000 mm bore (0.1966 – 2.7559 inch). Some combined bearings are constructed similar to drawn cups, but with an added thrust bearing component. Like other needle roller bearings, these combined bearings can be matched with an optional inner ring or thrust washer as the opposing raceway.

Track rollers are designed with outer rings of large radial cross section to withstand heavy rolling and shock loads on track-type or cam-controlled equipment. The outside diameters of the outer rings are either profiled or cylindrical. Profiled track rollers are designed to alleviate uneven bearing loading resulting from deflection, bending or misalignment in mounting. Stud-type track rollers are available with or without lip contact seals, or with shields. Yoke-type track rollers are designed for straddle mounting. Each yoke-type is available with both radial needle roller and cage assemblies, or with a single (or double) full complement row of cylindrical or needle rollers.

These are the most commonly found ball bearings in the manufacturing industry, commonly used for automobiles, household appliances, garden tools, office machinery, etc.

Thrust needle roller and cage assemblies are complements of small diameter needle rollers arranged in a spoke-like configuration. Needle rollers are equally spaced by means of a cage whose web section separates the rollers and provides guidance to keep them tracking in an orbital path. The purpose of these assemblies is to transmit a thrust load between two relatively rotating objects while greatly reducing friction.

Deep groove ball bearings are widely preferred across industries owing to its versatility. These are flexible to the needs of customers and come in various sizes. Their versatility is due to their ability to accommodate radial and axial loads in either direction, making them easy to maintain.

Our thrust bearings are available in 5 mm to 240 mm (0.1969 – 9.4488 inch) and have a complement of needle rollers held in place by a cage.

The outer ring in the form of a cup is accurately drawn and no subsequent machining is performed to build the outer raceway. Drawn cup needle roller bearings are available in open ends or single, closed-end designs. They are also available with one or two integral seals. Other options include a single lubricating hole and matching inner ring.

Full complement bearings handle high radial load-carrying capability. Caged bearings provide high speed and maximum lubricant-retention capability

When it is not practical to manufacture the shaft to raceway quality, an inner ring allows a customer to obtain acceptable bearing performance

Special manufacturing processes help increase roller fatigue resistance and minimize axial drift effects in critical applications.

Available in two basic designs: with an inner ring for straddle mounting in a yoke or with an integral stud for cantilever mounting

Our Stud type track rollers are available in 10 mm to 130 mm diameter (0.3937 – 5.1180 inch). The Yoke types are available in 10 mm to 300 mm diameter (0.3937 – 11.816 inch). They are characterized by their thick-walled outer rings that run directly on a track. The thick outer rings permit high load carrying capability while minimizing distortion and bending stresses.

Heavy-duty needle roller bearings are available in 5 mm to 335 mm bore (0.1969 – 13.1890 inch) and have machined and ground channel shaped outer rings with a complement of needle rollers retained and guided by a cage. The thick outer ring provides maximum load capacity and shock resistance with a relatively small radial cross section.

Founded in 1946, National Engineering Industries Ltd (NEI) is India’s leading bearings manufacturer and exporter, renowned for excellence in quality and delivery.

The designs provide maximum cage strength consistent with the inherently high load ratings of needle roller bearings. Accurate guidance of the needle rollers by the cage bars is allowing these bearings to operate at high speeds. Also available are needle roller and cage assemblies using molded, one-piece glass-reinforced engineered polymer cages. Needle roller and cage assemblies are manufactured with either one or two rows of needle rollers.

Loose needle and cylindrical rollers are mainly used as bearing rolling elements to reduce friction and torque rotating and pivoting applications. However, these precision rollers have many other uses, such as shaft or locating pins. Diameters are available from 1 mm to 15 mm (0.0394 – 0.5906 inch) Lengths are available from 2.5 mm to 69 mm (0.0984 – 2.7165 inch)

We have our own production facilities in the United States and Europe, and special customized products are available on demand. Our needle roller bearings are suitable for many applications such as:

Thrust needle roller and cage assemblies also can be unitized with lipped washers which service as raceway surfaces for the needle rollers. Washers can be supplied separately or can be mechanically unitized to the needle roller thrust assemblies for ease of handling all types have very small cross sections. If the backup surfaces cannot be used as raceways, hardened washers are available. Thrust bearings are also available with needle rollers or heavier cylindrical rollers for high load-carrying capacity.

Drawn cup needle roller bearings are available in 3 mm to 139.7 mm bore (0.1181 – 5.5000 inch). They support radial loads and reduce friction between rotating components, with a drawn outer shell serving as a raceway for the rollers. The small cross section of the drawn cup bearing provides high load-carrying capability with minimum required space. Drawn cup bearings are easily installed with a press fit in the housing.

Unearthing precious metals calls for some heavy duty work that needs a highly reliable set of equipment. From crushers and conveyors to drilling rigs, every

Drawn cup roller clutches and bearing assemblies are available in 3.2 mm to 35 mm bore (0.1250 – 1.3780 inch). These bearings are designed to transmit torque between the shaft and housing in one direction and allow free overrun in the opposite direction. When transmitting torque, either the shaft or the housing can be the input member. These designs use the same small radial section as drawn cup needle roller bearings and are offered as clutch-only units or as clutch and bearing assemblies.
