Needle Roller Bearing Cage Assembly
One-way roller bearings, also known as needle roller clutch, Needle Roller Bearing by the stamping outer ring and plastic cage; cage can bring their own plastic reed can also be on the stainless steel reed guide needle, the outer ring on the ramp and needle as Locking device. Needle Roller Bearing It is the surface with a groove, mainly for the empty bamboo manufacturing enterprises, has also launched a solid ring type one-way needle roller bearings, mainly for fitness equipment business, but also the development of ultra-thin one-way needle roller bearings, Needle Roller Bearing mainly for precision machinery enterprises. At the same time specializing in the production of fishing tackle with a one-way bearing, single-bearing, remote control model car dedicated one-way bearings.
The main structure type EG one-way bearing | one-way needle roller bearings EG - stamping outer ring needle roller clutch (one-way bearing) can be used as a converter, check device, Needle Roller Bearing beyond the clutch. HF (needle roller clutch): by the stamping outer ring and plastic cage; cage can bring their own plastic reed can also be on the stainless steel reed guide needle, the outer ring on the ramp and needle as a locking device. HFL (Clutch and Bearing Assembly): The bearing is mounted on both sides of the needle roller clutch and is subjected to a radial load. Needle Roller Bearing As a bearing, the needle roller and plastic cage assembly are supported.

Ramp and roller type single needle roller bearings are basically composed of a cylindrical inner diameter outer ring, a sloped inner ring and a group of rollers which are respectively subjected to spring force and are in close contact with the inner and outer rings. As long as the rotation of one of the raceways in the direction of its movement affects the other, this arrangement essentially ensures the immediacy of transcending speed and ensures immediate drive capability.
The wedge acts mainly by wedging and wedging wedges between the inner and outer rings. Needle Roller Bearing The basic concept of wedge one-way bearing requires that the friction coefficient of the wedge is related to the sudden torque of the inner ring in the driving direction. Needle Roller Bearing This friction value must be larger than the tangent value of the self-locking angle. If the conditions are unsafe, wedging will not occur.
The design of the wedge has a very low initial self-locking angle to ensure absolute combination at the beginning. As the torque increases, the wedge will produce a radial force that deflects the wedge raceway, Needle Roller Bearing causing the wedge to roll to a new position. The wedge is often designed to have a self-locking angle that can be gradually increased, as it is from the position beyond the maximum load. Needle Roller Bearing A relatively large self-locking angle can reduce the radial force produced by the wedge, so that a large torque is allowed to be delivered as long as the elongation and Brinell hardness limits are required.
