spherical roller bearings vs cylindrical roller bearings

Jun 21, 2023
1. What is Cylindrical roller bearing?

Cylindrical roller bearing is a type of bearing commonly used in the machinery and construction field, which can bear the axial direction and large radial load. The bearing structure consists of an inner ring, an outer ring, cage and cylindrical rollers. The inner and outer rings consist of cylindrical rollers that share a large load between them. Cylindrical roller bearings are commonly used in mechanical drive systems, rolling mill industry, mining industry and industrial robots. The use of cylindrical roller bearings can improve the heavy load capacity and anti- fatigue performance of machines.

2. Cylindrical roller bearing number

Product series include: Single row cylindrical roller bearings, NU series , N series , NJ series and NUP type. High load cylindrical roller bearings, NCF series , NJF series and NUH type. Double row cylindrical roller bearings, NNU series, NN series and NNUP type. Four row cylindrical roller bearings FC, FCD type, FCDP type. Single row full complement cylindrical roller bearings, NCF and NJG type. Double row full complement cylindrical roller bearings, NNCL, NNCF, NNC and NNF type.

4. The difference between cylindrical roller bearings and spherical roller bearings

Cylindrical roller bearings are often used to bear larger radial loads and axial loads because their design allows them to bear these loads. Because of the longer length of the rollers, cylindrical roller bearings are able to support a larger load bearing area for the same size.

Conversely, spherical roller bearings are designed to support larger axial loads and higher eccentric loads because their rollers can rotate between the inner and outer rings, thereby accommodating higher deviations. In addition, spherical roller bearings have higher stiffness and better self-alignment properties.
