Product Description

This series of sealing ring products are composite-made from oil-resistant rubber and self-lubricating materials, featuring self-lubricating function and excellent sealing performance. They are suitable for oil-free lubrication sealing systems in high-speed reciprocating motion structures such as power tools, nail guns, torque wrenches, and impact drills. The products can maintain low wear and low resistance during long-term operation, improving the operating efficiency and service life of the entire machine. Supporting customization of various materials and structures.

PRODUCT FUNCTION

Self-lubricating surface design can reduce the friction coefficient under oil-free lubrication conditions, minimizing wear and heat accumulation at the sealing parts;

Effectively reducing the operating resistance of moving components, improving the tool's response speed and efficiency;

With low compression set, it ensures long-term stable sealing performance and avoids leakage risks;

Strong resistance to grease, high and low temperatures, and thermal aging, suitable for sealing applications under severe working conditions.
