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.
What's the Performance Features of 696 ZZ Bearings in Demolition Hammers?
The 698 ZZ bearing offers robust performance in demolition hammers,
designed to handle high-speed operation exceeding 5000 RPM while
ensuring no oil leakage due to its double rubber seals. These seals
also provide excellent dust protection, effectively preventing
external particles from entering the bearing interior. Built to
withstand significant shock loads, the bearing ensures reliable and
durable operation even under the harsh conditions typical of
demolition work. Its combination of high-speed capability, oil
retention, dust protection, and shock load resistance makes it
well-suited for the demanding applications of demolition hammers.
What's the Applications of the 696 ZZ Bearing?
The 698 ZZ bearing, it is utilized in machinery equipment requiring
high efficiency and low wear, such as vacuum dryers, textile
machines, and metal welders. In electronics and electrical devices,
its small size and high-speed performance make it ideal for fans,
micro motors, power tools, and medical devices. Additionally, it
plays a crucial role in industrial automation, supporting smart
devices like robotic vacuum cleaners and office equipment such as
printers. The bearing’s precision and reliability also extend to
specialized applications in plastic packaging, barcode equipment,
and ceramic processing machinery, highlighting its versatility and
importance across diverse industries.
