Page 8: Safety Information
The spring-applied brake must only be operated in perfect state. • Retrofittings or changes of the spring-applied brake are generally prohibited. In any case, INTORQ GmbH & Co. KG must be contacted. • The friction linings must be carefully protected from grease or oil since even small amounts of lubricants reduce the brake torque considerably. -

Please take into account that the friction value and thus the torque depend on the speed. Stop! The spring-applied brakes INTORQ BFK457, sizes 01 to 16 use spacers (1.6). It is not possible to readjust the brake in the event of wear. If necessary, the rotor must be replaced. -

Page 15: Operating Frequency / Friction Work
S results in the permissible friction work Q perm With high speed and friction work, the wear increases strongly, because very high temperatures occur at the friciton faces for a short time. BA INTORQ BFK457 EN 2.0... -
Page 16: Emission
Depending on the natural oscillation after installation, operating conditions and state of the friction faces, the brake may squeak during braking. Others The abrasion of the friction parts produces dust. With large loards, the frction face heats up so strongly, that odours may occur. BA INTORQ BFK457 EN 2.0... -
