65Mn Black Oxide Open Spring Bushing
A formed spring-steel sleeve with an open cylindrical structure, designed to provide elastic radial force for positioning, retention and assembly applications.
Product Overview
This open spring bushing is manufactured from 65Mn spring steel and finished with black oxide. Its split cylindrical body can flex slightly during installation and recover to apply radial spring force against the mating component.
The product is suitable for mechanical positioning, retention, spacing and assembly applications where a compact formed metal sleeve is required. Dimensions and structural details can be customized according to customer drawings, samples and installation requirements.
Key Features
Provides controlled elastic deformation during installation.
Selected for its strength and spring characteristics.
Provides a dark industrial appearance and basic surface protection.
Diameter, length, wall thickness, opening and edge details can be produced to specification.

Structure and Function
Unlike a flat retaining ring, this component is a cylindrical spring sleeve. The longitudinal opening allows the body to compress or expand slightly during assembly. After installation, its spring force helps maintain contact with the mating surface and supports stable positioning.
Typical Applications
Mechanical positioning and retention
Automotive and industrial assemblies
Shaft, housing and sleeve connections
Equipment, fixtures and formed-metal assemblies
Custom Manufacturing
Shangers supports custom production based on 2D drawings, 3D models or physical samples. Please provide the inner diameter, outer diameter, length, wall thickness, opening structure, material requirements, surface finish and order quantity for evaluation.
