BendPak uses UHMW (ultra-high molecular weight polyethylene) load bearings because they are resistant to chemicals, weather, wear, etc. and will never need to be replaced as long as you own your lift. Other companies use roller bearings that require lubrication. UHMW load bearings never need to be lubricated or maintained.
A single-piece, pilot-fitted machined steel piston is built into every XPR-9S two-post lift. The piston is built into every hydraulic cylinder and includes pressure-loaded U-cup piston seal, backups and wear bands that prevent fluid from leaking over the piston. The chrome piston rod itself is micro-smooth and machined from high-yield C-1045/50 micro-alloy steel that is ground and expertly polished to a diametric minimum of .001". This supports a longer cylinder lifespan.
In fact, BendPak designs its car lifts with high-durometer and mechanically loaded rod seals, so the rods never leak. Urethane rod wipers are resistant to abrasion and offer total exclusion protection. The welded cylinder is constructed from strong steel tubing that easily exceeds ASTM specifications for certification. By offering a solid base in addition to high-quality processing, BendPak ensures that your two-post lift will be straight, smooth and durable for many years to come.
