Product Description:
Pin shaft is a key basic component used for connection, fixation and load transmission in mechanical equipment. This product is made of high-quality alloy steel, carbon steel or stainless steel through precision turning, grinding processing, heat treatment (quenching, tempering) and surface treatment (chrome plating, zinc plating, blackening, etc.). It features extremely high dimensional accuracy, mechanical strength and wear resistance. We provide various standard and customized specifications of pin shafts widely used in engineering machinery, automotive manufacturing, aerospace, industrial equipment and heavy machinery fields, ensuring reliable connection and long service life.
Features:
- High Strength and Hardness: Made of high-quality alloy steel with heat treatment, surface hardness up to HRC50-60, core maintains good toughness
- High Precision Dimensions: Precision grinding processing, diameter tolerance can be controlled within ±0.01mm, excellent straightness
- Excellent Wear Resistance: Surface treated with hard chrome plating, carburizing, etc., wear resistance improved by 3-5 times
- Corrosion Resistance: Stainless steel material or surface zinc plating, nickel plating treatment, suitable for various harsh environments
• • Diversified Design: Various structural forms including split pin holes, threaded ends, shoulder design, etc.
