Rolling Needle Bearing Features

The roller bearing is a roller bearing with cylindrical rollers, which are thin and long relative to their diameter. This roller is called a roll pin. Despite its smaller cross-section, the bearings still have a high load tolerance and the roller bearings are fitted with slender and long rollers, making them compact in radial.

The bearing carrying capacity is large, suitable for the support structure with limited mounting size, the shaft neck surface is hardened as a rolling surface, and the bearing is pressed into the seat hole with pressure into the seat hole, and no further axial positioning is required. Bearings should be injected with the right amount of grease before installation, usually, after assembly, no longer need to lubricate BK-type bearings for the shaft neck without anouting support, the end surface closed to act as a seal, and can withstand small axial movement.

The roll needle bearings are fitted with thin and long rollers, so the radial structure is compact, with the same internal diameter size and load capacity as other types of bearings, with the smallest outer diameter, and is particularly suitable for support structures with limited radial mounting dimensions. The rolling needle bearings vary according to the use of different, processing accuracy and surface quality should be combined with bearing collars and uses.

Rolling needle bearing is a very important mechanical components, generally in a lot of mechanical equipment will be used in it, so its application is very wide, because its use and maintenance are very convenient, so it is also favored by merchants, generally in industrial production is a large number of production.
