Is to use short cylindrical roller bearing roller bearing, tapered or drum-shaped roller for rolling element bearing.
Mainly has the centripetal short cylindrical roller, double row spherical roller to the heart, such as taper roller and thrust roller structure.
Roller bearings mainly has the centripetal short cylindrical roller, double row spherical roller to the heart, such as taper roller and thrust roller structure.
Cylindrical roller bearing this kind of roller is mainly used for cylindrical roller bearings, roller components can also be directly used in the machinery.
This kind of roller has been standardized in the size, can be used as commodity roller for design and the user to choose from.
Long cylindrical roller bearing diameter of axle of the roller points with and without the trunnion with two kinds, it is mainly used for long cylindrical roller bearings, roller components can also be directly used in the machinery.
Needle roller bearing this kind of roller is mainly used for needle roller bearings, needle roller bearings of universal joint and thrust needle roller bearing, and needle component can be directly used in the machinery.
This kind of roller on the dimension has been serialized, for design to choose from.
According to the need of the bearing structure, the ends of the needle head has a cone head shape, flat, round head, etc.
Tapered roller bearings are circular truncated cone, the cone Angle is usually 1 ° ~ 4 ° 20 ', there are less than 1 ° or greater than 4 ° 20 ', 2 °.
The length of the roller is generally not more than two times the diameter of the roller large end.
This kind of roller more for tapered roller bearing, large taper Angle of roller basically is used in the thrust tapered roller bearing.
The angled roller rolling spherical roller bearings are of spherical shape.
Using this kind of roller bearing with automatic self-aligning properties, can withstand the large load.
Spherical roller asymmetrical type and symmetrical type, general asymmetric large end face for the sphere, symmetric shape of two end face for flat end face.
Symmetrical form spherical roller with good performance, rather than to eliminate form of symmetrical type.
This kind of roller for spherical roller bearings and thrust spherical roller bearings.
Spiral roller bearing it is using a special section of the steel strip rolling of hollow roller, left-handed and a right-handed.
The roller is not very widely used, mainly for the screw roller bearings by impact load.
Bore pillar pillar roller bearing roller center hole, the hole for pillar, and to maintain shelf fixed to the sheet pillar.
This kind of roller shape is cylindrical, conical, spherical shape, and is mainly used for oversize bearings.
1 bearing roller machining process.
The processes of cylindrical roller blank forming - burring or band - soft grinding the raceway surface - soft grinding double - heat treatment - before the coarse grinding roller surface - coarse grinding double - after roughing rolling surface to eventually double end face grinding, fine, end mill rolling surface to super finishing rolling surface, cleaning, drying and final inspection group - oil packing appearance, size.

The technological process of the tapered roller blank forming - burring or band - soft grinding the raceway surface - soft grinding double - heat treatment - coarse grinding roller surface grinding balls - fine grinding roller surface - base - end mill rolling surface - super finishing rolling surface to clean, dry, final inspection group - oil packing appearance, size.
Above two kinds of roller can make crown bus bar rolling surface, if the convex metric is less than 0.
005 mm, generally can be directly in the super finishing rolling surface process;
If a convex metric is greater than zero.
005 mm, generally available in the last final rolling surface process grinding out the crown, then superfinishing.
3.
Needle to deburring, heat-treatment process of billet to thick, thin, end mill rolling surface, super finishing rolling surface polishing or sawdust.
For flat and cone head needle, such as blank shape is difficult to guarantee the length size tolerance, it can increase the double end face grinding in the mill rolling process.
If you need crown shape bus bar rolling surface, can be directly in the super finishing rolling surface or channeling light process.
4.
Asymmetric spherical roller type process of the blank shape - burring or band - soft grinding the raceway surface - soft grinding double - heat treatment and grinding of ball end to end face grinding balls, thick, thin, end mill rolling surface to polishing, cleaning, drying and final inspection group - oil packing appearance, size.
Symmetrical spherical roller processes is: rough shape - burring or band - soft grinding the raceway surface - soft grinding double - heat treatment - coarse grinding roller surface - thick, double end face grinding to fine, end mill rolling surface, polishing, cleaning, drying and final inspection group - oil packing appearance, size.
If the final rolling surface grinding process can reach surface roughness requirements, not for polishing.
