A round bushing pad (also known as a lower bushing, tool bushing, or wear bushing) is a cylindrical component mounted in the lower part of a hydraulic breaker. Its primary role is to guide the working tool (e.g., chisel, moil, blunt); absorb lateral forces; reduce wear between the working tool and breaker housing; and maintain tool alignment during operation.
- Design:Cylindrical/round internal diameter: Precisely machined to match the tool shank;High wear resistance: Designed to endure friction and impact;Interchangeable: Typically pressed or bolted into the lower housing and replaceable as part of routine maintenance;Grease grooves or holes: In some models, bushing pads are designed with lubrication paths to support automatic greasing systems.
- Applications: Bushing pads are critical components in all hydraulic breakers, regardless of size or application, ensuring smooth and aligned operation of the working tool.
- Quarrying and mining
- Road construction
- Demolition
- Trenching and utility work
- Recycling operations
- Materials: Hydraulic breaker bushing pads are manufactured using high-grade wear-resistant steels and undergo specialized treatments for durability.
- Configuration: Machine Type: SB202/SBU220/SB302/SBu340, SB52/SB102/SB152/EC40/EC50
