Lock Plate 15068658 | High-Strength 5140 Alloy Steel for Piston Assembly Securement

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.
