What is the error of digital display caliper ± The allowable error of 0.02mm is ± Of course, this is not the required error of the bearing, but the allowable error of the caliper. The required error of the bearing is -0.01mm. In the manufacturing process of the bearing, more accurate measuring instruments should be used to detect it (as shown in Figure 2)
The picture on the screen is a special bearing error meter, which can measure the bearing error with an accuracy of ±0.01mm. This is a composite industry standard. We use this instrument to complete the measurement and inspection in the production process
Bearing grease, we use low temperature - 20 ℃ - 120 ℃ grease, which is no problem for the use of a lawnmower, this grease can play a role in lubrication, reduce noise and friction, reduce the pressure of the bearing when rotating
Advantage: Our Premium Quality Bearings Come Standard With High Temperature, High Wear Resistant Grease for Long Life.Seal - Preserve grease and prevent impurities from entering. Compared with Bushings, bearings have lower friction and longer life, reducing your maintenance time and costs.
