Needle roller bearings use needle rollers as their rolling elements rather than balls. The term "needle roller" usually means that its length is several times its diameter.
roller bearing needle have a smaller cross-sectional height and could keep the entire machine lighter and more compact, thus maintaining a relatively high load carrying capacity. The key components are the cage (also known as the separator or support) and the needle rollers.
Needle roller and cage assembly can be mounted directly as a stand-alone accessory, or cam roller bearings can be used in conjunction with other parts, inner and outer rings, to form complete needle roller bearings that can be used as stand-alone bearing support mounts.
Needle Roller Bearing Advantages
Needle roller bearings, developed by THB, as one of the most professional needle roller manufacturers in China, have the following advantages:
Because of the small radial cross section of needle roller bearings, they are very suitable for working conditions where the mounting space is small
Optimized needle roller and raceway shape design, so that the bearing has a higher radial load capacity
Needle roller bearings are a bearing that is classified as either radial or thrust depending on the direction of the load being supported. Needle roller bearings include bearings whose rollers slightly exceed the size range of needle rollers as stipulated by ISO. Needle roller bearings include drawn cup and solid radial bearings, as well as application-specific cam followers, and roller followers.

Needle roller bearing are used in applications where compact size is required and radial space is limited. This is because these needle roller bearing only carry pure radial load and can not limit the axial displacement of shaft relative to the housing. They have a smaller cross-section, higher load-carrying capacity and greater rigidity, which in turn gives size and weight reductions in machinery. Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings. Additionally there is less added clearance so they are much more compact. The typical structure consists of an inner race, a needle cage which orients and contains the needle rollers, the needle rollers themselves, and outer race. Radial needle bearings are cylindrical and use rollers parallel to the axis of the shaft. Thrust needle bearings are flat and use a radial pattern of needles. Headsets in bicycles use a crooked pattern, so they are able to absorb both parallel and thrust power impacts. Needle bearings are heavily used in engine components such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive vehicle typically has at least 8 needle bearings (4 in each u joint) and often more if it is particularly long, or operates on steep slopes. We have a vast range of needle bearings available in different sizes and tolerances for various applications. Our needle roller bearings and cage assemblies are available in single row, double row, solid cage, split cage and metric as well as inch sizes. . Single and double row bearings are available with or without ribs, and with or without inner rings. Thrust bearings are available in single row roller and cage assemblies.
