Needle Bearings
A needle roller bearing uses needle rollers, rather than balls, as its rolling elements. Sometimes the simpler term roller bearing or needle bearing is used instead. The term “needle” typically implies that the length is several times greater than the 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.
There are a wide variety of needle roller designs that OTOTRI 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.
OTOTRI manufactures needle 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.
OTOTRI is a multinational supplier of needle roller bearings for applications including automotive steering and seating systems, agricultural equipment, electronics products and medical devices.
OTOTRI bearing design engineers are among the most knowledgeable in the industry, and our ability to manufacture on both sides of the globe gives Hartford customers a substantial advantage in cost and flexibility. Our prototype lab and manufacturing facilities are both geared to fast turn-around, and can accommodate major programs with stringent delivery requirements. OTOTRI is ISO 9001 certified.
OTOTRI-Automotive offers a wide range of needle roller bearings.
Compared to standard roller bearings or ball bearings, needle roller bearings have a greater contact area between the needles and the needle roller raceway. The resulting line contact is responsible for the high radial load-bearing capacity. The radial bearing play of the needle roller bearings can be adjusted via the shaft and housing tolerance.
This bearing type has a high radial load capacity with a very low cross-sectional height and is therefore particularly suitable for tight installation spaces with small diameters.
Due to their simple and compact design, needle roller bearings are particularly easy to assemble and can be used economically.
Needle roller bearing types:
Needle roller and cage assemblies (needle rollers with cage)
Needle sleeves, needle sleeves (outer rings made of thin-walled deep-drawn sheet metal)
Solid needle roller bearings (with solid inner and outer rings)
Sleeve freewheels with bearings (one-way clutches with needle rollers and sprags)
In addition to the common standard needle roller bearings, OTOTRI-Automotive also offers customer-specific special designs with special seals, lubrication grooves / bores, materials and types of grease.
