Unthreaded Smooth Assembly Spacer Bushing

RC-SB-004

Description

Non-threaded hollow cylindrical spacer with smooth inner bore, same tubular structure as RC-BS-001, produced in batches for multi-layer stacked assembly, used for gap filling, component positioning and shaft lining.

Manufacturing Process

Fixed-length tube cutting → both ends deburr → dimensional calibration → ultrasonic cleaning → quality inspection

Material

Low carbon steel / Stainless steel / Aluminum alloy

Surface Treatment

Blue-white zinc plating / yellow zinc plating / stainless steel passivation / black oxide

Features

Strict dimensional consistency for mass assembly, smooth inner surface to prevent shaft scratching, wear resistant metal body for repeated disassembly, customizable wall thickness for different load demands, stackable structure for multi-part spacing
