Features and advantages

◎ Heat-treatment, which is integrated heating and surface spray cooling under highpressure, to improve internal mechanical properties to prevent deformation under heavy load. meanwhile high pressure hardness and deep harden depth result in longer life.

◎ O-ring: Have better oil leaking resistance and high-temperature resistance

◎ Raw material of steel purchased from good steel groups to ensure quality.

◎ Assembly line has multiple workbench, The rollers are automatically washed before assembling by the washer to guarantee the cleanness and sealing performance of the production.

Possible problems with the roller

(1) Wheel wear. The reason for this is that the steel used is not qualified or the hardness of the material is low during heat treatment, and the wear resistance is insufficient;

(2) Oil leakage. The axle of the roller is rotated by the sleeve, and the wheel body needs to be lubricated to lubricate. However, if the sealing ring is not good, it is easy to cause oil leakage, so that the shaft and the sleeve are easily worn without lubrication. The product cannot be used. The reasons for oil leakage are as follows: 1. The floating oil seal is unqualified; 2. The roundness of the product bushing is not enough; 3. The gloss of the support shaft is not enough; 4. The gear oil is not up to standard; 5. The machining dimensional tolerance and so on. All of these problems will cause the roller to leak oil.
