Newly developed rolling diaphragm
actuators are used in ModEvo,
producing more force than previous
designs to allow higher torque ratings.
However, the sensitivity for which
rolling diaphragms are favored is not
compromised. Three actuator options
are available, offering clamping forces
of 100%, 60% or 25%.
The finned, die cast aluminum brake
module is common to all brake disc
diameters. Each module houses two
pairs of actuators, and allows friction
pads to be changed quickly without
dismantling the module.

To provide maximum flexibility when
selecting the required torque/tension
range for an application, two pad
options are available, with different
coefficients of frictions: Low (µ=0.20),
color-coded orange; Standard (µ=0.35),
color-coded grey. Pad types may be
mixed within a single brake assembly
to provide an exact match to the
machine requirements.
Friction Pad Options
The optional guard has a plastic front
with ‘ModEvo’ molded in and a metal
ventilated perimeter.
Mounting is by four brackets on
customer’s machine frame.
The center of the guard is designed
such that it may be cut-out by
customer to suit the diameter of the
shaft in through-shaft installations.
