Product Description

Technical requirement

1. The bearing and bearing seat should be filled with cyprin-based grease, and the amount of bearing oil filled is 2/3 of the bearing gap The seat oil cavity should be filled.

2. The inside of the cylinder should be cleaned before installing the shaft.

3, the physical properties of the roller surface adhesive and the base adhesive should meet the requirements of GB10595-89.

4, the quality classification of weld defects should meet the requirements of GB/T19418 Class B.

Producing different standards pulley:Production scope Diameter:φ114mm-φ2400m, Length:260mm-3400mm.

The pulley directly was made by large seamless steel:We precisely cut the tube by using the flame cutting machine, and weld the inner pulley disc by using the professional pulley welding machine, and weld the pulley sleeve & disc by using the positioner. We use the large drum lathe process the outside circle, so that it ensures the pulley has the uniform thickness and small pulsation. We chose 45# round steel & sleeve and process the whole shaft so that it ensures shaft concentricity and reduction for the eccentric shaft force. It make sure the pulley move more stable, high-quality bearing which is hot charging and bearing block are equipped inner bearing Enlargement Device, so the bearing can be easily pushed to the bearing position  and it avoids the bearing damage from the beating.We need make the eliminating inner stress treatments when the pulley's withstand forces exceed 80KN and we will make the static balance inspection when the belt
