Product Name

Precision Steel Tube Machining Service for Shaft and Sleeve

Model Series

GH-PTMS-SS Series

Product Overview

Gilan Hardware Private delivers high-precision machining services for steel tube-based shafts and sleeves, transforming raw seamless or welded tubing into finished components with micron-level accuracy. Utilizing advanced CNC turning centers, deep-hole honing systems, and cylindrical grinders, we manufacture critical tubular parts including piston sleeves, hollow drive shafts, guide bushes, and bearing housings. Our integrated process chain—from tube cutting to final surface treatment—ensures consistent dimensional integrity and superior surface quality for demanding mechanical applications.
