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.

• Eliminates loosening and rotation issues with diamond knurl outer surface in press-fit applications.
• Solves wear problems of plastic or soft material holes with a durable brass and nickel-plated inner bore.
• Reduces assembly failure risk with tight tolerance machining and consistent knurl quality.
• Cuts design iteration time with fast custom prototyping and flexible material/finish options.
• Avoids corrosion in humid environments with nickel-plated brass construction.

• Raw material inspection includes chemical composition verification and hardness testing.
• CNC turning process is monitored for dimensional accuracy and surface finish.
• Knurl pattern quality is checked for full coverage and consistent pitch.
• Plating thickness and corrosion resistance are tested according to standards.
• 100% dimensional inspection is performed on all finished parts before packaging.
