The shaft for pad in a hydraulic breaker refers to a key mechanical component that supports or transmits impact force to or from other breaker partscommonly associated with the pad assembly, tool retention system, or guide mechanism. It may act as a retainer pin, guide shaft, or part of the wear pad assembly depending on the breakers internal design.
- Design:
- Cylindrical or stepped geometry:Precision-machined for tight tolerances
- Shouldered or grooved ends:For proper positioning and load transfer
- High load-bearing capacity:Designed to handle both axial and radial loads during operation
- Surface finish:Smooth and hardened to reduce friction and wear against mating parts
- Applications:
- Tool Retention: Holds or aligns the chisel/moil/blunt tool within the breaker
- Wear Pad Assembly: Acts as a guide or structural part of the bushing/pad systems
- Force Transmission: Helps distribute impact force safely across the breaker housing
- Component Alignment: Maintains alignment of internal breaker parts under vibration
- Materials: High-strength alloy steels selected for high toughness and fatigue resistance. Heat treated to absorb shock and prevent brittle fracture.
- Configurations: SB52, SB102, SB152, SB202/SBU220, SB302/SBU340, SB452
