Application Scenarios

It is used for bucket tipping action drive of 5-ton wheel loaders, suitable for earthwork, quarry mining, sand yard, bulk cargo loading and other high-intensity working conditions.

• Manufactured strictly according to OEM standards, the pin hole spacing, oil port position and mounting size fully match the original assembly, direct installation without modification, cutting or reaming, greatly lowering assembly errors and saving maintenance downtime.
• Precision honed cylinder tube plus hard chrome-plated piston rod, low friction coefficient, good wear resistance, resistant to mud splash and rust, stable performance in dusty and humid construction sites.
• Built-in buffer structure at both ends of stroke, effectively absorb the impact when the bucket reaches the limit, suppress instantaneous pressure surge, protect seals and hydraulic pump from shock damage.
• Multi-combination sealing system, including dust ring, wear ring and high-pressure sealing ring, good resistance to high pressure and oil soaking, slow aging speed, low oil leakage risk under frequent reciprocating action.
• Integral forging hinge lug design, high structural rigidity, not easy to deform under heavy digging load, strong resistance to bending and torsion during repeated impact.
• Standard supporting interface, compatible with original hoses, split flanges and hydraulic valves, convenient for spare parts stocking and quick on-site replacement.

FAQ 

Q1: Can this tilt cylinder work under pressure higher than its rated working pressure?
A1: No. Exceeding rated pressure will cause piston seal extrusion failure, permanent deformation of cylinder barrel, severe oil leakage or even cylinder burst. Long-term overpressure will bring irreversible fatigue damage to the cylinder body, even if the pressure returns to normal later, safety risks still remain.

Q2: What are the common causes of oil leakage of the tilt cylinder?
A2: It may be aging and damage of piston sealing set, dust ring scratched by sand and gravel, loose threaded oil port, impact scratch on cylinder barrel, or piston rod bending deformation leading to uneven compression of seals.

Q3: What should be noticed before installation?
A3: Clean the oil ports and inner cavity to remove welding slag, metal debris and dirt; check that all sealing parts are intact; align the hinge pin hole, avoid forced assembly, and lubricate the hinge pin before installation.

Q4: Can a slightly scratched piston rod continue to be used after simple polishing?
A4: It is not recommended. Simple grinding will damage the original hard chrome protective layer. Without the chromium coating, the rod will corrode rapidly, and the scratch will cut the sealing ring repeatedly during movement, which is prone to repeated leakage. It is better to replace the whole cylinder assembly.

Q5: What are the requirements for the hydraulic oil used for this cylinder?
A5: It is recommended to use L-HM46 anti-wear hydraulic oil. Dirty, deteriorated or water-emulsified oil contains hard particles, which will scratch the inner wall and damage the sealing assembly, accelerating the wear of the cylinder.
