This custom knurled press fit bushing is precision machined from high-quality brass H59 bar stock. It features a diamond-knurled outer surface for secure press-fit installation, preventing rotation and pull-out, while the smooth threadless inner bore provides a low-friction, wear-resistant guide surface. The nickel-plated finish enhances corrosion resistance and improves surface hardness. We offer full OEM & custom service to tailor dimensions, materials, knurl patterns and plating treatments to match your exact design requirements for locating inserts, reinforced sleeves and press-fit components.
As a professional custom manufacturer, we offer comprehensive OEM solutions for knurled press fit bushings and inserts. We support custom dimensions (outer/inner diameter, length) based on your drawings or samples. We provide multiple material options including brass H59, stainless steel and carbon steel. Custom knurl patterns, plating treatments and tolerance requirements are also available. We handle everything from prototype machining to mass production with reliable lead times.
