Integrated manufacturing coordination
Built for demanding applications
Replacement sleeves for critical equipment
When original parts are discontinued or OEM lead times are unfeasible, SleeveMFG provides a reliable manufacturing alternative. We reverse-engineer worn components and reproduce the dimensions, material, and surface finish required for functional replacement.
Our sleeves support both field service and new equipment programs, helping you restore operating tolerances or maintain consistent production supply.
Discuss your component requirementsShaft sleeves
Precision components for protecting shafts and restoring critical fits in rotating assemblies.
Wear sleeves
Machined replacements for components exposed to friction, abrasion, and demanding service conditions.
Seal sleeves and precision bushings
Custom sleeves and related rotational components produced to your dimensional, material, tolerance, and surface-finish requirements.
Manufacturing capabilities
Technical control from raw material to finished sleeve
Our Dongguan facility uses an integrated workflow to manage complex geometry, tight fits, surface integrity, and production consistency.
Dimensional range
OD Ø3 mm–Ø500 mm
ID Ø1 mm–Ø450 mm
Length up to 1500 mm
Geometric control
Concentricity, roundness, cylindricity, and radial runout controlled down to 0.005 mm–0.01 mm.
Material diversity
304, 316, 17-4PH, 4140, 4340, 52100, bronze, and nickel alloys.
Surface integrity
Surface finishes down to Ra 0.2 μm for demanding sealing and rotating applications.
One coordinated workflow
Reduce handoffs across the production process
Managing separate suppliers for machining, heat treatment, grinding, and coating can add risk and lead time. SleeveMFG coordinates the complete manufacturing process for a more controlled supply path.
-
