CRAxx-x Standard combined bearings

● Installation method of forklift mast bearing
The commonly used installation method of mast bearings is the shaft fixed with the matching retaining ring. The matching between bearings and shafts is generally transitional matching, and the tolerance of shafts is g6 or h6. The axial direction is limited by the standard shaft retaining ring. In addition, there are also half-hole bearing screw fixation, shaft fit gland fixation, and other methods.

● Static pressure test of forklift mast bearing
The bearing capacity of mast bearings is usually tested by a static pressure testing machine. The inner wheel of the bearing is fixed and the outer wheel is linearly pressurized and loaded to the preset load or until the bearing is damaged.

● Life test of forklift mast bearing
The life of mast bearings is measured by a special life-testing machine. According to the parameters such as the dynamic load rating, the theoretical life and test time are calculated. The inner wheel is fixed, the outer wheel load rotates, the running test is carried out until the preset time or until the bearing is damaged, and the temperature rise and the amount of grease leakage are monitored synchronously.

● Impact test of forklift mast bearing
The impact resistance of mast bearings directly affects the reliability of bearings. Fix the bearing in the special testing machine, raise the drop hammer with a certain weight to the designated height to fall freely, hit the outer wheel of the bearing, and raise the drop hammer height step by step until the bearing is damaged.
● Salt spray test of forklift mast bearing
Forklift mast bearings used on special occasions are usually coated with blackening, phosphating, electroplating, etc. A salt spray test is required to verify antirust ability. Place the bearing in a sealed salt spray testing machine, atomize a certain proportion of salt spray, and monitor the antirust ability of the surface layer at different times.
