Wantong specialize in large multiple stage single acting telescopic hydraulic cylinders. We offer a full line of four stage, single acting telescopic cylinders with five standard series of sizes. These range from a smallest (final) moving stage O.D. size of 5 inches to 10 inches. Wantong Hydraulic Telescopic Cylinders can replace existing telescopic cylinders and retrofit to any existing truck dumper. Wantong Telescopic Cylinders meet or exceed O.E.M. specifications.

  Well Engineered: Wantong Telescopic Hydraulic Cylinders are engineered to achieve truer and smoother operation in heavy duty applications. Our fully welded type construction, which incorporates a generous lap between stages for more stability and rigidity, allows our cylinders to have a higher stress and side-loading threshold.

   Wide Bearings: The use of extra wide internal bronze bearings means greater low friction surface for our telescopic cylinders to operate. This wider bearing surface aids in the prevention of side-loading, which ultimately causes scoring within the tube and sends damaging metal particles throughout the hydraulic system.

   Effective Seals: The sealing system used is stacked V-packing rings or single lip “U-cups” molded specifically for Wantong Telescopic Cylinders. Wantong packing is compatible with standard hydraulic oils. Special packing materials are available when required by the specification of non-standard hydraulic fluids.

   Accessible Packing: Packing is accessible under external gland nuts, removable with supplied spanner wrench, allowing ease of packing adjustment or replacement.

   Quality Control: Our quality control program is continuous throughout the production of each telescopic cylinder. All telescopic cylinders are pressure tested before leaving our plant and designed to operate at a maximum of 2,000 PSI.
