According to the use of parts and conditions of use and environmental conditions, select the size, accuracy, and suitable non-standard bearings are the premise to ensure bearing life and reliability.

Location of use: Non-standard bearings are suitable for combined radial and axial loads that are dominated by radial loads. They are usually paired with two sets of non-standard bearings. They are mainly used in front and rear wheels, active bevel gears, and differential speeds of automobiles. Transmission parts such as gearboxes and reducers. Allowable speed: Under the environment of correct installation and good lubrication, the allowable bearing speed is 0.3-0.5 times.

Selection of bearing grease

Improper lubrication accounts for 36% of the causes of premature failure of non-standard bearings. General-purpose greases cannot meet the needs of various special bearing applications. Only one or all kinds of general-purpose greases are used to meet all bearing applications. , The problems caused will far exceed the benefits brought by the unified brand. Bearing application conditions are very diverse. Proper lubrication requires that the grease matches the bearing application conditions.

Bearing grease is the basis for ensuring smooth, worry-free operation and maximum reliability of the bearing, even under the most extreme working conditions. Grease prevents contaminants from entering the bearing, cushions impact loads and prevents corrosion. Choosing the right grease in practical applications is the basic condition for obtaining the maximum service life of bearings.

The criteria for the correct selection of lubricants include the type and size of non-standard bearings, temperature, speed, load and the expected service life and relubrication cycle.

The initial radial clearance of the bearing gradually decreases during the pushing-in process, and the pushing-in amount determines the degree of fit. Therefore, the initial radial clearance of non-standard bearings must be measured before installation. During the pushing of the bearing, the radial clearance is continuously measured until the required radial clearance reduction and the ideal interference fit are achieved.
