INTORQ BFK458-L in materials handling technology

In high-cycle applications, spring-applied brakes are subject to two kinds of stress. Due to the large number of load alternations, the service life of the brake is determined both by the mechanical components of the brake itself and the useful life of the rotor, which is based on friction energy. In particular, the rotor/hub connection, the springs and the sleeve bolts are subject to wear due to the number of load cycles. Based on the components mentioned, without additional measures the ser vice life of spring-applied brakes is limited to 1x106 to 4x106 load cycles depending on the load.

Guaranteed performance data:

• Guaranteed service life of brake mechanism:

1. 10x10⁶ repetitive cycles of operation
2. 15x10⁶ reversing cycles of operation

• The brake warranty covers either two years or the guaranteed number of cycles - whichever is reached first.
• The scope of the warranty in the event of premature failure covers replacement of the brake, including a flat-rate replacement fee.
