Product Q&A
Q:What sizes do you offer? Which belts and buckets do they fit?
A:
Our standard sizes cover M6,M8,M10,M12,M16 with lengths from 16mm to 100mm, suitable for conveyor belts 3mm to 20mm thick and most common bucket/hopper models. Custom inch sizes are also available.

A:
They are designed for bucket elevators, belt conveyors, and elevator systems, widely used in grain, mining, construction materials, chemical, and feed industries.
Q:What material are they made of? How is the rust resistance?
