Can tungsten carbide shaft sleeves be manufactured according to drawings?

Yes. KENIN Carbide can manufacture tungsten carbide shaft sleeves, pump sleeves, seal sleeves, wear sleeves, and other custom carbide shaft protection components according to customer drawings, samples, 3D files, or detailed technical requirements. Inner diameter, outer diameter, length, stepped structure, grooves, slots, surface finish, tolerance, and carbide grade can all be customized.

Can the carbide grade and surface finish be customized?

Yes. Carbide grades can be selected according to working medium, abrasive particles, load, pressure, temperature, rotational speed, and required service life. Surface finishes including precision grinding, polishing, lapping, and customized sealing surface finishing are available according to drawing requirements.

What information is required for a quotation?

Please provide the drawing or sample, shaft diameter, inner diameter, outer diameter, length, required quantity, working medium, pressure, temperature, rotational speed, tolerance requirements, and any surface finish or mechanical seal requirements.

What is the difference between a tungsten carbide shaft sleeve and a tungsten carbide bushing?

A tungsten carbide shaft sleeve is generally installed around a rotating shaft to protect the shaft surface and provide a wear-resistant or sealing contact surface. A tungsten carbide bushing is more commonly used as a guide, support, bearing, or positioning component within a housing or assembly. The final design depends on the equipment structure and operating conditions.

Tungsten Carbide Shaft Sleeves

Precision tungsten carbide shaft sleeves for pump shafts, mechanical seals, rotating equipment, and wear-resistant shaft protection.

Product Overview

Tungsten Carbide Shaft Sleeves are precision wear-resistant components designed to protect rotating shafts and provide stable working surfaces in demanding industrial equipment. Manufactured from cemented tungsten carbide, these sleeves offer excellent hardness, wear resistance, dimensional stability, and reliable performance under abrasive, high-pressure, and high-speed operating conditions.

Carbide shaft sleeves are commonly installed on pump shafts, mixer shafts, agitator shafts, mechanical seal assemblies, and other rotating equipment where conventional metal sleeves may wear rapidly. Their precision-ground or polished surfaces help protect the underlying shaft, reduce wear at sealing or bearing contact areas, and extend equipment service life.

KENIN Carbide manufactures standard and custom tungsten carbide shaft sleeves according to customer drawings, samples, mating shaft dimensions, working media, pressure, temperature, and service requirements.

Applications

Tungsten carbide shaft sleeves are widely used in rotating equipment and sealing systems requiring long service life, wear resistance, and stable sealing surfaces.

Typical applications include:

Pump shafts and slurry pump assemblies
Mechanical seals and seal support systems
Chemical process pumps
Oil and gas equipment
Mixers, agitators, and rotating process equipment
Valve stem protection and rotating valve components
Mining and abrasive fluid handling equipment
Power generation equipment
Paper, pulp, and wastewater treatment machinery
High-pressure and high-speed industrial machinery
