Spherical Roller Bearings

A spherical roller bearing consists of an outer ring with a spherical raceway and a double raceway inner ring, one or two cages, and a set of spherical rollers. Because the center of the outer ring spherical raceway and the bearing center, so has a spherical performance, can automatically adjust the tilt or shaft deflection due to the angle error between the shaft and the bearing seat. Its ability to withstand large radial load, a certain two-way axial load, for the heavy load or vibration of the occasion is particularly suitable.
Spherical roller bearings have cylindrical bore and tapered bore two kinds. TWB spherical roller bearings have C type, CA type, MB type, and other structures, suitable for different occasions.

  —–2RS Sealed Bearings

The bearings come with contact seals on both sides, which are made of oil and wear-resistant rubber with a steel backbone. TWB currently offers two rubber seals: Nitrile Rubber (NBR) and Fluorine Rubber (FPM). Fluorine rubber can emit toxic gases at temperatures up to 300°C, so care should be taken when selecting this material. Seal bearings should never be cleaned or heated above 80°C before installation. When replenishing grease in sealed bearings, it is necessary to slowly inject oil into the lubrication hole of the outer ring and rotate the bearing while doing so, so that the new lubricant can be evenly distributed in the bearing. In addition, excessive pressure should be avoided to prevent damage to the seals.
