Needle bearing is used in many mechanisms that are involved in construction, agriculture, automotive industry and other industries. Products can be used in various conditions. Needle bearings consist of a recessed outer race, a set of rollers guided and held by a cage.
The outer thick ring bears the highest load capacity and is shock resistant. Needle bearing with high-strength cage, guide and retainer rollers provides the required speed and retains grease.
Products are used with or without a machined outer ring. These mechanisms have found applications in pulleys, gear pumps, two-stroke engines and automotive transmissions.
The needle bearing may have guide rollers which are characterized byouter thick-walled ring, moving directly along the guide. Such rings withstand heavy loads with minimal bending and deformation effects. This needle bearing contains a complete set of rollers and is available in two designs: with an integral trunnion for cantilever mounting and with an inner ring for shackle mounting.
To facilitate installation, a socket for a hex key or a hole for a screwdriver is made in the trunnion head. Sealed design with internal thrust washers increases product life. The main applications of these devices are sorting units and lifting mechanisms.
The needle roller bearing with a stamped outer ring is excellent for absorbing radial loads and reduces friction between rotating elements. The small cross section of these products makes it possible to withstand significant loads with minimal dimensions. The mechanism is simply mounted by pressing into the case. Closed end needle bearings are also produced.
The scope of the described devices is very wide. They are used in transmissions, engines, transfer cases, valve trains, steering systems and brakes.
With their help, bridge supports, outboard motors, copiers, power tools, fax machines, variousappliances.
Sealed bearings and closed end versions are also available. These devices are used in mechanisms that operate at high speed.
Thick-walled outer forged ring products are used in systems where the shaft is operated at a large angle of inclination, such as hydraulic pumps and axle shafts. Thin-walled ring mechanisms provide radial support with a small cross-sectional area.
Such devices have weight and size limitations. They are used in gearboxes.
