Heavy Duty Compression Springs, Black Coil Style, 1.7" Outer Diameter x 1.25" Inner Diameter x 3.9" Free Length, 1/4" (218 Gauge) Wire, 163 lbs/in Rate for Equipment Repair,2 Pack
Product Information: Product dimensions are 1.7 inches (OD), 1.25 inches (ID), and 3.9 inches (free length); wire diameter is 1/4 inch; spring rate is 163 pounds per inch; each set contains 2 pieces.
Product Features: This black heavy-duty compression spring offers multiple functions including shock absorption, elastic return, heavy-load support, clearance compensation, and energy storage transmission. Its robust structure resists deformation, meeting the shock absorption, load-bearing, return, and assembly compatibility requirements of various mechanical equipment.
Compatibility: Suitable for industrial machinery, landscaping equipment, agricultural machinery, home appliances, automotive parts, hardware transmission systems, and various repair, replacement, and modification scenarios requiring shock absorption, load-bearing support, and elastic return.
High-Quality Materials: Precision-engineered from high-strength alloy steel, featuring a reinforced wire gauge for a robust structure. The surface undergoes a black hardening treatment, ensuring high toughness, excellent compression resistance, and minimal deformation. It offers stable fatigue resistance and springback, with long-lasting performance that resists loosening and wear.
When to Replace: Replace the spring promptly when it exhibits reduced elasticity, fails to rebound under pressure, shows significant deformation or bending, displays surface cracks or wear, exhibits fatigue or loosening, produces abnormal noises during operation, or provides insufficient support. This ensures the stability of equipment operation and safe use.
