Rubber Piston Rings

Rubber piston rings.

This allows pressure build up on one side of the piston making the cylinder extend or retract. Rubber piston seals or piston rings are used in hydraulic cylinders for fluid sealing. The moving piston rod generates high pressure on the piston seal which increases contact forces between the seal and cylinder surface. With strong alliances to specialty molding houses we can provide custom molded shapes and hard to find sizes and materials.

To minimize this they are made of wear resistant materials such as cast iron and steel and are coated or treated to enhance the wear resistance. As rings become thinner this heat transfer function becomes even more critical. They are internal to the cylinder head and seal against the cylinder bore preventing fluid from flowing across the cylinder head. Before we delve into materials the responsibilities of a piston ring must be reviewed.

The friction made by piston rings is roughly 33 of the total resistance of the engine. While sealing combustion pressure is the obvious goal an equally important function is to transfer heat from the piston to the cylinder wall.

For this reason the surface properties of the sealing surfaces are critical to proper seal performance. Rubber o ring vulcanization bonding duration. Rubber seal 156 352 views. Having a suitable piston ring will minimize its friction and maintaining an excellent sealing to increase the lifespan of the engine.

Stocked in our 10 000 square foot warehouse and available for immediate delivery we have everything from simple o rings to complex metal bonded to rubber products. Piston seals maintain sealing contact between a piston and cylinder bore. The rubber piston ring should fit perfectly to avoid thermal throttle and severe damage to the engine.
