1.Product description

A needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers resembling needles. Ordinary roller bearings' rollers are only slightly longer than their diameter, but needle bearings typically have rollers that are at least four times longer than their diameter. Needle bearings have the advantage of greater load carrying capability vs. ball bearings. Theoretical contact is a line (needle roller bearings) compared to a point (ball bearings). Key components are a cage (also known as a separator or retainer) and needle rollers. Other components, if they are present, essentially function as inner or outer races.

2.Product advantages 

1.Needle Roller Bearing from Spring Bearing is thinner than conventional roller bearings and can be designed with or without an inner ring. Needle roller bearings are ideal for dealing with radial space constraints in heavy-load, high-speed applications. Drawn cup styles allow for high load capacities and large grease reservoirs while still offering a slim cross-section design. These bearings are offered with inch or metric seals.

2.Spring Bearing manufactures needle bearings for radial loads that demand a low profile. These are exceptionally easy to install.

3.The kinds of design

There are a wide variety of needle roller designs that Spring Bearing produces. Plastic molded retainers coupled with bearing grade steel rollers are one option. Alternative needle roller bearing designs include a metal stamped cage and chrome steel needle rollers. Also, sometimes the cage / retainer is machined.

While in other cases, there is no cage. Full complement needle roller bearings use the maximum amount of rollers. Occasionally grease is used to hold the rollers in place until the needle roller bearing is assembled onto a shaft. In other cases, a temporary plug holds the bearing together until assembly. In yet other cases, the needle rollers hold each other together by virtue of their close proximity and geometry, similar to how a keystone works in a masonry arch.
