What is the guaranteed rotational fatigue strength?

The pulley, including the welding part, is guaranteed to have a rotational fatigue strength of over 10^8 cycles.

What quality tests are performed on the pulley?

Circumferential and longitudinal welds undergo non-destructive testing, and the casting quality of the wheel hub undergoes magnetic particle or ultrasonic testing.

Product Q&A

Q:What surface types are available for the conveyor pulley?

The pulley is available in smooth, rubber lagging, or ceramic rubber lagging surfaces, with options for coal bonding or hot vulcanization adhesive treatment.

Q:What is the maximum belt width supported?

The conveyor pulley supports belt widths ranging from 650 mm to 3400 mm, with standard diameters varying accordingly.

Q:How is the shaft connected to the wheel in heavy-duty models?

For medium and heavy-duty pulleys, the shafts and wheels are connected by expansion sleeves, which eliminates stress concentration and welding internal stress.

Q:What is the static balance accuracy of the pulley?

All drums undergo static balance tests before leaving the factory to achieve G40 accuracy, ensuring rotation balance.

Q:What materials are used for the pulley pipe and shaft?

The pulley pipe is made of Q235B carbon steel with high roundness and straightness. The shaft uses 45# round steel or according to your requirements, with ultrasonic inspection and quenching treatment.
