⚙️ Product Description High Durability

Δ High strength, High abrasion-resistance, High-reliability Prolong service life

1Steel Tube: Seamless alloy tube same as hydro-cylinder; Higher nominal loading torque; Shot blasting before welding.
2External Strips: Alloy material heat-treated; High hardness and abrasion-resistance.
3Locking Plate: Heat-treated alloy; Tail structure reduces cracking tendency; Robot cutting.
4Upper Guide Ring: Three moving rings; Wear and impact resistance.
5Drive Shell: Robot cutting/welding; Integral arc plate; High wear resistance.
6Terminal Joint: Overlapping plates; Small tendency for cracking.
7Anti-friction Plate: Full-rotating; Reduces wear on pipe ends and stopper plates.
8Tool Joint: Integral forging (length ≥ 1.2m); Significantly reduces weld load.
