The Difference Between Trenching Bearings And Grinding Bearings

Trenching bearing is digging grooves on the shaft and then putting balls or rollers into the groove to reduce friction and wear by rolling. Grinding bearings are used by grinding grooves on the shaft and then putting balls or rollers into the grooves, also by rolling to reduce friction and wear. The main difference between the two is that the manufacturing process is different.

• Trenching costs are low and processing speed is fast, but further finishing may be required in high-precision applications.
  

• Despite the high processing costs and long processing times, the grinding groove provides excellent bearing performance, especially in environments with strict requirements for friction, noise and life.
  

• Trenching is suitable for efficient mass production, but may be inferior in precision and finish;
  

• Despite the high cost, the grinding groove can provide excellent accuracy and surface quality, which is suitable for demanding application scenarios.

Ditching and grinding play different roles in the manufacturing process of deep groove ball bearings, and the choice of which process depends on the application needs of bearings and production conditions.  Understanding these differences helps to make the best process choices when designing and manufacturing bearings.
