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.

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.

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).

There are a wide variety of needle roller designs that Hartford Technologies 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.

Hartford Technologies is a multinational supplier of needle roller bearings for applications including automotive steering and seating systems, agricultural equipment, electronics products and medical devices.

Needle roller bearings have needle rollers as rolling elements. In terms of rolling bearing technology, cylindrical rolling elements are classified as needle rollers if the rolling element diameter is ≦6 mm and the ratio of the rolling element diameter to the rolling element length is Dw/lw ＜ 1:3.Due to the small diameter of the rolling elements, all needle roller bearings have the common feature of a low radial section height. Due to the line contact, they are particularly suitable for bearing arrangements with high radial load carrying capacity and rigidity in a restricted radial design envelope.Radial needle roller bearings can only be used as non-locating bearings. The defined axial displacement value in the case of bearings with inner rings allows axial motion between the shaft and housing. Where necessary, wider inner rings are available for larger displacement values.

Hartford Technologies manufactures needle roller bearings for radial loads that demand a low profile. These are exceptionally easy to install.

A needle roller bearing decreases friction and efficiently transmits torque in applications including off-highway and oil patch equipment, drive shafts, outboard engines and air compressors. A high load needle bearing is specified for applications that involve static loads, low speeds, or oscillation.
