PRS cylindrical roller bearings have been used on high speed machines

With the rapid development of the wind power equipment industry, especially the high-power fan is becoming more and more mainstream, the reliability of fans and parts will be the focus of research and development.

Cylindrical roller bearings are linear contact roller, its load capacity and stiffness is higher than the point of contact with the angular contact ball bearings, usually guided by two ribs of a bearing ring, cage, roller and guide ring composed of a The assembly, which can be separated from another bearing ring, is a detachable bearing. The installation and disassembly are more convenient, and the inner ring and the outer ring can be separately installed. Especially when the inner ring and the outer ring are required to have an interference fit with the shaft and the shell, the advantage can be more clearly demonstrated. This kind of bearing is generally only used to bear radial load, compared with the deep groove ball bearing of the same size, there is a greater radial bearing capacity, the limit rotational speed close to deep groove ball bearing. PRS cylindrical roller bearings include five product lines, including single-row, double-row, four-row and other conventional models of cylindrical roller bearings, can also provide special models based on user requirements for the development and production.

Common failure modes of high-speed shaft bearings: Cylindrical roller bearings and four-point contact ball bearing combinations are common in high-speed machine applications. At high speed and low load, cylindrical roller bearings are susceptible to roller slippage and raceway scratches, while ball bearings may suffer from scratches and micro-peeling.

Solution: PRS proposed cylindrical roller bearings with anti-wear coating and single row tapered roller bearing. Cylindrical roller bearings with a wear-resistant coating can continuously prevent slippage during the entire life cycle, and can also prevent raceway damage and poor lubrication due to impurities in the lubricant. Single-row tapered roller bearings can withstand radial and biaxial axial loads, and their pure rolling characteristics minimize the possibility of scratches.
