High-Strength Lock Plate for Hydraulic Breakers Engineered to secure piston assemblies in high-pressure hydraulic breaker systems, this lock plate ensures reliable vibration resistance and torque retention under extreme operating conditions. Constructed from 5140 alloy steel with a heat-treated finish (36-42 HRC), it withstands cyclic loading and wear, making it ideal for heavy-duty mining and construction equipment.
Technical Specifications & Design The lock plate adheres to ISO 10100 standards for hydraulic cylinders, featuring a 75 mm outer diameter with a 40 mm inner diameter. Its four symmetrically placed M8 mounting holes (45 mm bolt circle diameter) ensure uniform clamping force distribution. The precision-serrated edges (60° angle) create a non-slip engagement with mating surfaces, preventing loosening under vibration.
Performance Advantages
Vibration Resistance: Maintains 40-50 N·m torque after 10,000 vibration cycles, exceeding industry standards for hydraulic fasteners.
High Strength: 1000 MPa tensile strength and 10⁶ cycle fatigue resistance ensure long-term durability in high-stress environments.
Wear Protection: 36-42 HRC hardness minimizes abrasion and deformation during repeated use.
Precision Fit: Symmetric design and tight tolerances ensure correct alignment during installation, reducing downtime.
Applications
Hydraulic Breakers: Critical for securing piston assemblies in Sandvik-compatible hydraulic breakers used in mining and quarrying.
Shock Absorption Systems: Used in hydraulic rock drills to maintain component alignment under high-frequency vibration.
Industrial Machinery: Supports presses and material handling equipment requiring reliable fastener retention.
