The need to stop any machine rotating part

will force you to select a device working

without any external power supply.

KEST spring applied caliper brakes

are the solution of this problem;

braking force is always available

due to springs mounted in the brake.

Technical data

Braking force F:

KBS4-1 2625 N

KBS4-2 5250 N

KBS4-3 10400 N

Dynamic torque

= F*(disc radius in m - 0.033) = Nm

Max total wear: 12 mm

Thickness of new lining: 11 mm

Continuous thermal capacity Qc: 3.4 kW

Minimum release pressure: 5 bar

The torque values specified

are obtained with n. 4 springs for 4-1,

n. 8 springs for 4-2 and 4-3.

Torque proportionally less

are achievable with n. 2 springs for 4-1,

n. 6-4-2 springs for 4-2 and 4-3.

The diagram shows the torque

variation for each millimeter

of linings wear.

Adjust according to ensure the

correct torque value is achieved.
