  Common Load Forms Of Roller Bearings

  The roller bearing is derived from the need for low speed and heavy load and the large size and large angle of rotation. To put it plainly, the turntable bearing is a comprehensive load that can withstand large axial loads, radial loads and overturning moments at the same time. Large-scale bearings with special structure of rotation, transmission, fixed and other functions in one. The turntable bearing device can withstand m...

  Ways to extend bearing service life for high speed applications

  Wear and tear naturally occur over time for any bearing. For parts used in high-speed applications, the negative effects of wear and tear can become a major issue much sooner. High-speed applications create a pair of problems for your bearing’s wellbeing: more heat and friction. Without proper planning and precautions, the added heat and friction caused by high-speed use can cause churning, slippage, and early breakag...

  WSBC Roller Bearing Types and Applications

  Roller bearings — also known as rolling-element bearings — are similar to ball bearings in that they are designed to carry a load while minimizing friction. However, roller bearings transmit loads using cylinder rolling elements, rather than balls, to maintain the separation between moving parts of the bearing. These versatile bearings can contain single or multiple rows of rolling elements; multiple rows can s...

  The Reasons Affecting Ball Bearing Speed

  Ball bearings are mainly composed of four basic components: ball, inner ring, outer ring and retainer, also called cage or retainer.General industrial ball bearings meet AISI 52100 standards. The balls and rings are usually made of high chromium steel with Rockwell C-Scale hardness of approximately 61-65.The hardness of retainer is lower than that of ball and ring, and its materials are metal (such as medium carbon steel, al...
