Spherical Roller Bearings

Spherical Roller Bearings

Spherical roller bearings are designed to adapt to severe misalignment caused by mounting or deflection on the shaft & housing. Not every type of bearing has the ability to face the challenge of misalignment. Meanwhile, due to its two row of rollers, spherical roller bearings are able to bear high radial loads and some axial loads. They adopt a spherical or crowned rollers as rolling elements and raceway of the outer ring is also in spherical shape. For shock loads, their feature of self-aligning helps to absorb but has limited capabilities to high speed. As one of the widely used bearings, spherical roller bearings do you a favor in obtaining lower maintenance cost, increasing the productivity and prolong the service life. 

Spherical Roller Bearings Types

Features of spherical roller bearings are as follows

  • Adapt to misalignment

  • Reduce friction

  • Extend the service life

Therefore, spherical roller bearings are proper for low/medium speed but heavy or impact load.They have both cylindrical and tapered bores which can match with adapter and withdrawal sleeves. Spherical roller bearings can be divided into single-row, double-row and thrust ones. 

ZWA’s spherical roller bearings are their most advantageous products, involving different cage type from CC, E to CA, MB and MA. Diameter is from inner ring 50 mm up. The bearings from ZWA have served customers from steel, mining, cement, paper making etc. Cooperating with the suppliers of world top bearing brands elevates ZWA bearings’ competition with world name branded bearings. 

As the substitute of imported bearings, ZWA bearings keep improving the quality step by step. In recent years, in order to improve the quality and make bearings competitive, ZWA bearings set up two labs, optimize the cage design, adopt the same raw materials of name branded bearings, narrow the tolerance scope, elevate the precision, improve the packing... All the measures are aiming at provide the most cost-effective bearings for the customers.

ZWA Bearing Recommendations
  • Split Bearings
    Split Bearings
    Split roller bearings are specially designed based on the original spherical roller bearings and cylindrical bearings. The aim of split bearings is to solve the problem of quick replacement of bearings at unattainable positions or points. They are suitable for the application of lower rotating speed, higher load, shock loads, harsh working conditions and those positions where it is hard to access. ZWA’s split bearings include split spherical and split cylindrical roller bearings.
  • Double Row Tapered Roller Bearing
    Double Row Tapered Roller Bearing
    It is classified into 2 types: capped and open. Both of them can bear radial and double row axial loads.
  • Double Row Spherical Roller Bearing
    Double Row Spherical Roller Bearing
    Double-row spherical roller bearings are the most widely used types in group of radial roller bearings. They have two rows of rollers, curved raceway in the outer ring and two raceways in the inner ...
