  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...

  How to install longer service life

  Thrust tapered roller bearings can only bear one-way axial load and can limit the one-way axial displacement of the bearing, so they can be used as one-way axial positioning. Compared with thrust cylindrical roller bearings, the bearing capacity is large and the relative sliding is small, but the limit speed is low. Matching method: interference fit of shaft and bearing box with shaft ring and seat ringInstallation met...

  Three Ways of Roller Bearing Cage Guide

  Cage (namely bearing cage, also known as bearing retainer), refers to the part of the bearing that partially wraps all or part of the rolling body, and moves with it, to isolate the rolling body, and usually guide the rolling body and keep it in the bearing. When rolling bearings are working, bearing heating and wear are caused by sliding friction. Especially under high temperature operation conditions, the effect of i...

  Why Cylindrical Roller Bearings Only Bear Radial Loads

  WSBC Cylindrical roller bearings are generally only used to bear radial loads. Only single-row bearings with ribs on the inner and outer rings can bear smaller directional axial loads or larger gap axial loads. What is bearing load? Bearing load is the load received by the bearing during use, including lateral load and longitudinal load. Click here for more details about WSBC 23120-2CS . ...

  Measurement Before Bearing Installations

  When installing rolling bearings, the dial gauge should be fixed on the end face of the box shell first, so that the top of the contact head of the meter can migrate the transfer bearing on the raceway of the bearing shaft ring. While migrating the transfer, check the dial gauge pointer. If the pointer is swaying, it is clear that the shaft ring and the middle line of the shaft are not vertical.If the shell hole is deeper, y...
