Furthermore, all specified restrictions apply to the standard and wear-resistant friction linings (e.g. per-
missible operating frequency, permissible friction work, reactivation during operation as a holding
brake, breakaway torque after extended rest, temperature range, etc.).
The classification of the safety function of our brakes is based on the performance levels PL in accordance
with DIN EN ISO 13849-1:2015. This can be used to support the verifications of the functional safety of
drive systems. The safety characteristic data are available on request.
3.2 Layout
This chapter describes the variants, layout and functionality of the INTORQ BFK458 spring-applied brake.
The basic module E is adjustable (the braking torque can be reduced using the torque adjustment ring).
The special feature for basic module L (with an identical design) is the more durable materials (torque sup-
port, guide pins, toothed intermediate ring, friction lining and gear teeth). The double spring-applied brake
design is especially useful in redundant braking applications.
