Description
QP series pneumatic caliper disc brakes are mainly used for braking and decelerating various mechanisms in machinery such as lifting, transportation, metallurgy, mining, port, construction, etc.
■ Conditions of use
● Ambient temperature: -5℃~40℃
● Working air pressure: 5-7bar for QP series; ≤7bar for CQP series.
● Outdoor rain and snow erosion or corrosive gases and media should use anti-corrosion products.
● The air source should be free of oil, water and other impurities.
