The rolling body of the cylindrical roller bearing is the centripetal rolling bearing of the cylindrical roller bearing. The internal structure of cylindrical roller bearing is arranged in parallel with rollers, and spacer or spacer block is installed between rollers, which can prevent the inclination of rollers or the friction between rollers and effectively prevent the increase of rotary torque.
Cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bear radial load. The rolling body has little friction with the rim of the ring and is suitable for high-speed rotation. According to whether the ring has flanges, it can be divided into NU, NJ, NUP, N, NF and other single-row cylindrical roller bearings, and NNU, NN and other double-row cylindrical roller bearings. The bearing is a detachable structure with inner ring and outer ring.
Cylindrical roller bearings with inner ring or outer ring without flanging, the inner ring and outer ring can move relative to the axis, so they can be used as free-end bearings. One side of the inner ring and outer ring has double stops, and the other side of the ring has a single stop cylindrical roller bearing, which can bear a certain degree of axial load in one direction. Steel plate cage or solid cage made of copper alloy is generally used. But some parts use polyamide forming retainers.
