With the continued interest in caliper brakes in both electric and hydraulic styles, some Ogura customers have also requested that Ogura produce a pneumatic style spring-engaged caliper brake. From these requests, Ogura has developed two series of spring-applied, pneumatically released caliper disc brakes. These are the ANB-1100-CP and ANB-2300-CP. The 1100-CP has 11,000 newtons of clamping force and the 2300 has 23,000 newtons of clamping force. The actual torque applied to a given application is a function of the diameter of the disc. The disc for either brake would be customer supplied.
The new brakes from Ogura have stationary cylinders that make them highly reliable and very resistant to vibration. Even though the brakes can produce a tremendous force, they are relatively lightweight for their size and take up significantly less space than an equivalent single-face brake. They are suitable for wind turbines and railcar shuttle equipment because any time pneumatic pressure is lost, the brakes can come on and hold in an emergency.
