JAMA is an ambitious cast iron pulley manufacturer. We have progressed from the beginning through our own organic evolution. The bearing wholesalers series is available in a wide range of types and specifications. JAMAcast iron pulley is designed with a combination of different effects. The designers, based on the ergonomics, strive to create a product which integrates the shock absorption, bending, and slip prevention. This product can effectively improve sleep quality by increasing circulation and relieving pressure from elbows, hips, ribs, and shoulders.

We are embedding sustainability into our business. We try to reduce the greenhouse gas emissions, waste, and water impacts of our manufacturing operations.
