HRBN---cylindrical roller bearing is a bearing unit composed of machined inner & outer races and cylindrical rollers. It is usually used as supporting bearing, one-way locating bearing or location bearing. Because of large amounts of cylindrical rollers with very high dynamic load and static load, it can bear bigger radial force and limited one-way & two-way axial force. With the property of high rigidity, this product is widely used in lathe, metallurgical and textile machinery; motor, driving shaft, gearbox and other location & supporting location.

Types of Designs:
Featuring single-row and double-row structure, linear contact between cylindrical roller & raceway, strong capability to bear radial load and structure with cages, it is suitable to the occasion of rotation in high speed. There are ribs in inner & outer races, so the product can bear axial load of certain degree and can be used as fixed side bearing. Most bearings are separable-type design which makes it easy to mount and dismount.

Product Precision Accuracy:
Dimensional tolerance and geometrical accuracy is based on GB/T307.
Matched cylindrical roller precision grade is Ⅲ (ISO GB/T4661).
Bearing radial running clearance conforms to the value defined by 0 group of GB/T4604.
For fuller information on the special requirements of bearing running clearance, inscribed circle and accuracy grade, please contact this company.

Materials:
Material for needle roller is GCr15 bearing steel, quench-hardening HRC60---65.
Material for inner and outer races is GCr15 bearing steel, quench-hardening HRC61---65.
Material for cages is quality low-carbon steel.

Special Directions:
Inside and thrust ring for fitting cannot bear any axial load.
Displacement range between inner and outer races should be considered.
Better rigid supporting is required for the ribs transferring axial forces.
For general-disposition design of bearings, refer to the relevant recommendation in the applied technology of rolling bearings.
