Requirements for Bearings in Demolition Hammers (Jackhammers)

A demolition hammer (also known as an impact drill or rock drill) is used for drilling or chiseling into hard materials like concrete and masonry. Given the harsh working conditions and high performance demands, bearings in demolition hammers have specific requirements to ensure reliability and durability:

Demolition Hammers typically require 4 sets of bearings, with the following specifications:

• High-Speed Operation: The bearings must be capable of operating at high speeds, generally exceeding 5000 RPM.

• Oil Retention: They should ensure no oil leakage during high-speed operation.

• Dust Protection: Provide excellent protection against dust, preventing external particles from entering the bearing interior.

• Shock Load Resistance: Able to withstand significant impact loads.
