Rubber coated balls combine a carbon steel or stainless steel core with a silicone or polyurethane (PU) outer layer. Ball size, coating material, thickness, hardness and color can be customized for valve components, cooling products, mechanical cushioning and other special applications.
Rubber coated balls combine the strength of a metal core with the cushioning, sealing or contact properties of an elastomer outer layer.
Rubber coated balls are commonly produced with carbon steel or stainless steel cores and coated with silicone or polyurethane (PU). The outer layer can help reduce impact, protect contacting surfaces and provide the required elasticity for different operating conditions.
Common applications include valve components, cooling products, mechanical cushioning and other customized uses. Ball diameter, core material, coating thickness, hardness, color and other requirements can be produced according to samples, drawings or confirmed application details. As each project is different, please contact our sales team for specification confirmation.
