Dacromet Surface Treatment Bushing
,Stainless Steel Step Spacer Sleeve
,Non-Standard Custom Locating Ferrule
This special-shaped step bushing is precision CNC turned from stainless steel, serving as a non-standard custom hardware spacer and locating component. Its step structure design enables positioning, spacing, load bearing, and anti-shifting functions. It is widely used in the assembly of automation equipment, smart brackets, instrument sheet metal, and similar scenarios. Situo Hardware supports custom manufacturing by drawing or sample — material, dimensions, tolerance, and surface treatment can all be adjusted to meet diverse equipment assembly requirements.
- Precision CNC turning ensures stable dimensions with controllable tolerances
- Special step structure for accurate positioning and assembly limitation
- Multiple material options: stainless steel, carbon steel, aluminum alloy
- Non-standard customization available — developed from drawings or samples to suit different assembly spaces
- Optional surface treatments: polishing, passivation, blackening, anodizing
- Wear-resistant and pressure-resistant, suitable for long-term repeated assembly
Automation jigs and fixtures, smart brackets, precision instruments, sheet metal assemblies, door and window hardware, medical devices, and conveying equipment — used for positioning, spacing, and buffering.
