Question 1

Can Xuanda build replacement cylinders for Loesche, UBE or other OEM vertical roller mills?

Accepted Answer

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.

Question 2

What is the difference between clearance seal, low-friction seal and hydrostatic support cylinders?

Accepted Answer

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.

Question 3

Can you manufacture a hydraulic cylinder from a worn sample without drawings?

Accepted Answer

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.

Question 4

Which industries does Xuanda Hydraulic serve?

Accepted Answer

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.

Question 5

What technical support is available after delivery?

Accepted Answer

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.
