Looking for high-quality oil seal springs that deliver stable tension, zero leakage and long service life? Guanglei Oil Seal Springs are engineered for reliability, with a wire diameter range of 0.1–0.8mm to fit all standard and custom oil seal sizes (10–300mm inner diameter). Our precision-manufactured springs are designed for automotive, industrial, marine, and food machinery applications, solving your biggest pain points of oil leakage, frequent replacements, and fitment issues.

Crafted from premium materials including SAE 1070 high carbon steel, 304/316 stainless steel, 65Mn manganese steel, and phosphor bronze, our oil seal springs offer tailored performance for every working condition. Whether you need corrosion resistance for wet or chemical environments, high strength for heavy-duty machinery, or non-magnetic properties for precision equipment, we have the perfect material solution to meet your requirements.

Our oil seal springs feature tight tolerance control (±0.01mm wire diameter tolerance) and consistent radial tension, ensuring a secure fit between the seal lip and shaft. Tested to 20,000+ fatigue cycles, they outlast generic springs by 30%, reducing your maintenance costs and equipment downtime. All products comply with ISO 6194 and GB/T 13871 standards, guaranteeing reliability and compatibility for global markets.
