The classification of bearing roller

1. Cylindrical roller 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. 2. Long cylindrical roller diameter of axle of the roller points with and without the diameter of axle with two kinds, it is mainly used for long cylindrical roller bearings, roller components can also be directly used in the machinery. 3. Needle roller is mainly used for this kind of needle roller bearings, needle roller bearings of universal joint and thrust needle roller bearings, needle component can be directly used in the mechanical. 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. 4. Tapered roller assumes the circular truncated cone, the cone Angle is usually 1 ° ~ 4 ° 20 ', there are less than 1 ° or greater than 4 ° 20 ', more than 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. 5. Angled spherical roller roller rolling 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. 6. Spiral roller which is in a special section of 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. 7. Pillar pillar hole hole roller 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.
