For more than 22 years, Changzhou Xuanda Hydraulic Electromechanical Equipment Co., Ltd. has designed, machined and tested heavy-duty and high-precision hydraulic cylinders for plant owners, OEMs and maintenance teams in 30+ countries. From vertical roller mill loading cylinders to closed-loop servo cylinders with ±1 μm positioning accuracy, every unit is engineered around your real operating load, duty cycle and installation interface.
Cylinders matched to original mounting dimensions and working parameters of mainstream vertical mills and roller presses.
Imported high-precision machine tools plus CAD/CAM/CAE design tools keep tolerances and batch quality consistent.
Selection, installation guidance, spare seals and repair or upgrade proposals for cylinders already in service.
Application-matched cylinders for grinding mills, roller presses and precision servo systems — built to hold force, alignment and sealing performance under continuous industrial duty.
Heavy-duty loading cylinders for Loesche LM series mills, built to the original installation dimensions and working parameters for direct replacement during planned shutdowns.

Changzhou Xuanda Hydraulic Electromechanical Equipment Co., Ltd. is a high-tech enterprise specializing in the R&D, design, manufacturing and technical service of hydraulic transmission and automation control solutions. Our core expertise is hydraulic cylinders for cement machinery and high-performance servo hydraulic cylinders.
We combine high-precision CNC equipment imported from Germany and Japan with CAD/CAM/CAE engineering tools and internationally recognized design practices. The result: cylinders that fit the first time, seal reliably and keep critical equipment running between planned shutdowns.
Market-oriented, quality-based, innovation-driven and integrity-built — with people-centered management and continuous system improvement.
Recent developments include a 300 kN hydrostatic servo cylinder for heavy lateral loads and integrated closed-loop servo cylinders with ±1 μm accuracy.
Focused on hydraulic cylinders and drive solutions
Engineers, machinists, assemblers and QC staff
Machining, honing, assembly and test in one site
Export packaging and documentation support
Transparent, engineering-led steps that reduce fit-up risk and unplanned downtime for overseas buyers.
We confirm load, stroke, speed, mounting, duty cycle, working medium and ambient temperature — from OEM drawings, nameplates or reverse-engineering of worn samples.
3D modelling and simulation check rod buckling, stress concentration and seal groove geometry before any metal is cut.
Tubes, pistons, rods and heads are machined on German and Japanese CNC equipment for repeatable tolerances batch after batch.
Bores are honed for a controlled surface finish, and rods receive wear- and corrosion-resistant surface treatment suited to the site environment.
Seal systems — standard, low-friction, clearance or hydrostatic — are selected for pressure, speed, temperature and required response.
Each cylinder is pressure, leakage and stroke tested before shipment, then protected and packed for long-distance sea or air freight.
High-precision CNC machines imported from Germany and Japan, disciplined lean production and engineers who understand how cylinders fail in the field.
Dedicated engineers translate site conditions into cylinder designs, covering force, speed, mounting and sealing for each duty.
Standardized workflows and in-process inspection keep quality consistent and deliveries predictable from prototype to batch orders.
Designs built to your drawings and applicable international standards, from general standard cylinders to specialized servo units.
Custom cylinder development plus lifecycle services: installation guidance, spare seal kits and repair or upgrade proposals.
Our cylinders operate in metallurgy, cement and building materials, shipbuilding, rubber & plastics and mining engineering — environments defined by heavy loads, dust, heat and 24/7 production targets. Quality leads the future.
Cylinders for rolling mills, continuous casting and heavy handling equipment exposed to high temperature and shock loads.

Yes. We manufacture loading and suspension cylinders that follow the original installation dimensions and working parameters of Loesche LM, UBE UM, TCD/TRM and similar vertical roller mills, as well as roller press cylinders for Chengdu Leejun CLF series. Brand names are trademarks of their respective owners; Xuanda supplies compatible replacement cylinders.
Clearance seal cylinders seal through a precision fit between piston and bore, giving almost zero friction and very high sensitivity. Low-friction seal cylinders use specialized seal compounds to reduce stick-slip in servo loops. Hydrostatic support cylinders float the piston and rod on a pressurized oil film, allowing them to handle heavy lateral loads and mixed high/low speed duty with minimal wear.
Yes. Our engineers can reverse-engineer a cylinder from a physical sample, nameplate data, photos and field measurements, then confirm a new drawing with you before machining begins.
Our cylinders are used in metallurgy, cement and building materials, shipbuilding, rubber and plastics, mining engineering, water conservancy and general industrial automation in more than 30 countries.
We provide full-lifecycle technical support, including installation guidance, commissioning advice, seal and spare-part recommendations, and repair or upgrade proposals for cylinders in service.
Product milestones, field applications and company updates from our engineering and production teams.
A hydrostatic support design keeps the rod floating on an oil film, delivering stable motion where conventional seals wear quickly.
