The cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bearing radial load. The friction between the rolling Cylindrical Roller Bearing Model element and the retaining edge of the ferrule is small, which is suitable for high-speed rotation.
According to whether the ferrule has retaining edge or not, it can be divided into single row cylindrical roller Cylindrical Roller Bearing Model bearings such as Nu, NJ, NUP, N and NF, and double row cylindrical roller bearings such as NNU and NN. The bearing is a separable structure of inner ring and outer ring.
Cylindrical roller bearing with no flange on the inner ring or outer ring, whose inner ring and outer ring can move relative to each other in the Cylindrical Roller Bearing Model axial direction, can be used as a free end bearing.
A cylindrical roller bearing with double retaining edges on one side of the inner ring and the outer ring and a Cylindrical Roller Bearing Model single retaining edge on the other side can bear a certain degree of axial load in one direction. Generally, steel plate stamping cage or copper alloy turning solid cage are used. However, some use polyamide formed cages.
Single row cylindrical roller bearings usually only bear radial force. Cylindrical Roller Bearing Model Compared with ball bearings of the same size, the radial bearing capacity is increased by 1.5-3 times, with good rigidity and impact resistance.
It is especially suitable for rigid supported shafts, short shafts, shafts with axial displacement caused by thermal elongation, and machine accessories requiring separate bearings for installation and disassembly. It is mainly used for large motors, machine tool spindles, front and rear engine support shafts, train and bus trunk shaft support, diesel engine crankshaft, automobile and tractor gearbox, etc.
Single row cylindrical roller bearing, including outer ring, inner ring, locking ring and cage. An annular stress groove is arranged in the middle of the outer wall of the outer ring, a plurality of annular locking grooves are arranged on the outer wall of the outer ring, and the shape and size of the locking ring are adapted to the shape and size of the annular locking groove.
A locking ring is arranged in the annular locking groove. An annular cage groove is arranged on the Cylindrical Roller Bearing Model annular surface of the inner wall of the outer ring corresponding to the stress groove. The utility model has the advantages of convenient assembly, large bearing load, high limit speed, strong reliability, long service life, etc.
The thrust cylindrical roller bearing is often combined into a high stiffness bearing configuration, which can bear heavy load and vibration load without difficulty. This kind of bearing can Cylindrical Roller Bearing Model bear large axial load in one direction, but can not bear radial load. They have no self-aligning ability.
Thrust cylindrical roller bearing can be divided into thrust cylindrical roller Cylindrical Roller Bearing Model and cage assembly, shaft ring and seat ring.
811 series and 812 series thrust cylindrical roller bearings are composed of thrust cylindrical roller and cage assembly, shaft ring and seat ring. The important parts are thrust cylindrical roller and cage assembly.
