LK Clutch or Brake Design Features

Clutch designed with total attention given to maximizing ventilation for cool running operation. Benefits
include: longer lining life; stable friction coefficients; and lower maintenance costs.

All materials selected and field proven to provide the best available resistance to wear and thermal distress.

Precision machining of all components ensures positive interchangeability of all mating parts.

S

elf-contained separator springs for
positive disengagements are integral
with each plate and cannot fall out
u

pon assembly or disassembly.

High quality non-asbestos lining
materials and maximum areas ensure
excellent heat dissipation and lining life.

Longest possible spline length incorpo­rated on the clutch discs to maximize the
load-carrying capacity and life.

Drive studs ensure free plate
motion during engagement and
disengagement. The use of
drive studs, rather than splines,
allows wear particles and other
contaminants to exit the clutch
as well as provides an excellent
path for cooling air flows.

Long life, low replacement cost piston seals.

Short-stroke lightweight alumi­num piston is contour machined
t

o match the cylinder recess and
provides for extremely fast clutch
response with minimal air
consumption.

Rotary seal and integral quick release valve
mounts directly to the clutch cylinder.
Custom drilled orifices per application and
clutch size in a large poppet style valve,
meters the inlet air to provide smooth,
shockless engagements and allows for
immediate release upon command.
