Stainless Steel Knurled Bushings Anti-slip and Wear-resistant Connections
Material Advantages: Made of high-purity 304 stainless steel with compliant nickel content, offering excellent rust and corrosion resistance. Suitable for complex working environments such as humidity, oil, and high temperatures, they are not easily oxidized or worn, with a service life of over 10 years, overcoming the defects of ordinary carbon steel bushings such as easy rusting and jamming.
Process Advantages: Machined using precision automatic lathes, with dimensional tolerances controlled within ±0.05mm. The knurling pattern is clear, uniform, and consistent in depth, providing excellent anti-slip performance and press-fitting effect. The bushing features high concentricity of its inner and outer circles, ensuring smooth and jam-free assembly, and withstanding frequent disassembly, assembly, and rotational friction.
Knurling Advantages: Straight-line knurling is suitable for interference fits and press-fit installations, increasing assembly friction; serrated knurling is suitable for manually gripped and adjustable parts, providing a comfortable and non-slip feel. Knurling angle and density can be adjusted to meet the requirements of different assembly methods.
Customization Advantages: We support customization of inner diameter, outer diameter, length, knurling type, and surface treatments such as polishing, passivation, and galvanizing according to customer needs, adapting to the personalized assembly requirements of different equipment. Bulk customization enjoys exclusive discounts, meeting the bulk purchasing needs of machinery manufacturers and automation equipment manufacturers.
Quality Advantages: Each batch of products undergoes triple testing for dimensional accuracy, knurling clarity, and hardness, meeting industry standards for precision mechanical parts. Only products that pass inspection are released, ensuring quality and preventing substandard products with out-of-tolerance dimensions or unclear knurling from entering the market.
Whether it’s equipment manufacturing, spare parts procurement, or custom assembly of non-standard machinery, it can meet the requirements for high precision, high wear resistance, and rust prevention. With its stable processing accuracy and reliable anti-slip performance, it has gained recognition from many machine processing plants and automation equipment companies.
