Контргайка с шестигранной головкой, M85 x 4 мм Caterpillar 5255498

The Special Lock Nut is used to provide a secure and stable connection between mating components by resisting loosening forces during operation. This nut incorporates a locking feature, such as a prevailing torque, and a deformed thread profile, which creates friction and interference to prevent unintended loosening. By maintaining consistent clamping force and thread engagement, the lock nut enhances reliability and safety.Attributes:• Supports high-speed rotational applications without dislodging.• Maintains torque even after thermal cycling.• Resists thermal expansion and contraction effects.Applications: The Special Lock Nut is used to secure the piston assembly inside the hydraulic cylinder, preventing loosening under pressure. It maintains reliable joint integrity during high-force hydraulic operations and repeated cycles.
