300 Series Cylindrical Roller Bearings V1 V2 Vibration ISO9001 Approved

DCM NU/NJ/NUP/N/NF 300 Series Single Row Cylindrical Roller Bearings P6 P5 P4 P2

Features

Cylindrical roller bearing is in linear contact with the rollers and has a large radial load capacity. It mainly bears radial load and is suitable for heavy load and impact load. When the friction between the rolling elements and the rib is small, it is suitable for high-speed rotation. According to the presence or absence of ribs, it can be divided into NU, NJ, NUP, N, NF and other types single-row cylindrical roller bearings, and NNU, NN and other types double-row cylindrical roller bearings. The rollers are usually guided by two ribs of a certain ring, while the cage, roller and the guiding ring form a combined component, which can be separated from the other ring, thus calling separable bearing.

DCM can produce high quality TRB as the customer requests.We are happy to produce further construction methods. Please do not hesitate to contact us for special bearing characters.We can also supply OEM service.

Product Specification

Cylindrical Roller Bearings are designed to handle radial load at high performance and speed. According to the presence or absence of ribs, it can be divided into NU, NJ, NUP, N, NF, NH and other single-row cylindrical roller bearings, and NNU, NN and other double-row cylindrical roller bearings.
The bearing has a separable inner ring and outer ring structure.Pressed steel or machined brass cages are generally used, but sometimes molded polyamide cages are also used.

Some cylindrical roller bearings have no ribs on either the inner or outer ring, so the rings can move axially relative to each other. These can be used as free-end bearings. Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.

Types NU, N, NNU, and NN are suitable as free-end bearings.
Types NJ and NF can sustain limited axial loads in one direction.
Types NH and NUP can be used as fixed-end bearings.
NH-type cylindrical roller bearings consist of the NJ-type cylindrical roller bearings and HJ-type L-shaped thrust collars.
The inner ring loose rib of an NUP-type cylindrical roller bearing should be mounted so that the marked side is on the outside.
