Roller bearings

  • Description

Needle bearing is a roller bearing with a cylindrical roller. The roller is thin and long relative to its diameter. This kind of roller is called a roller pin. Despite having a small section, the bearing still has a high load bearing capacity. The needle bearing is equipped with a thin and long roller(the diameter of the roller D ≤ 5mm, L/D ≥ 2.5, L is the length of the roller), so the radial structure is compact., Its internal diameter size and load capacity are the same as other types of bearings, and the outer diameter is the smallest. It is especially suitable for support structures with limited radial installation dimensions.

Depending on the occasion of use, bearings or roller and holder components without inner rings can be selected. At this time, the axial neck surface and the shell hole surface matching the bearing are directly used as the inner and outer rolling surfaces of the bearing. In order to ensure that the load capacity and operation performance are the same as that of the ring bearing, the hardness, machining accuracy and surface quality of the shaft or shell hole Raceway surface should be similar to that of the bearing ring Raceway. Such bearings can only withstand radial loads.
