Oil seal springs are tension springs with ends connected in a ring shape, widely used in oil seals, shaft seals, belt-driven motors, and electronic connectors. Their design provides consistent and stable tensile force, ensuring effective sealing and the reliable operation of mechanical systems, making them a critical sealing component.

Our company manufactures oil seal springs using various high-quality wire materials, including stainless steel wires (SUS304-WPB, SUS316-WPA), phosphor bronze wire (PBW), music wire (SWP-A/B), and hard steel wire (SWB/C), to meet different strength and corrosion resistance requirements across applications. We offer a wide range of surface treatments such as blackening, gold plating, tin plating, nickel plating, chemical nickel plating, zinc plating, colorful zinc plating, black nickel plating, passivation, chrome plating, phosphate coating, and electroless nickel plating, significantly enhancing product durability and corrosion resistance.

Combining advanced production equipment with strict quality control, we provide high-precision, high-quality custom oil seal spring solutions, ensuring stable performance and long service life. Please contact us for orders and inquiries to tailor the best spring solutions for your products.
