Durable, robust construction
Crossover Drives Wrap Spring clutches and clutch brakes are built stronger for longer,
trouble-free performance. Construction is all metal, with no plastic
or powdered metal parts to weaken and fail.
Bearings
Our oil-impregnated bronze bearings provide longer life than the sintered
steel bearings on competitive clutches. Teflon-lined, steel-backed (DU) type
bearings may be added for extreme temperatures. QCB models feature needle roller
bearings on harden and ground shafts for longer bearing life.
Springs
Heat-treated, stress relieved chrome-silicone steel, die-drawn for a
uniform rectangular cross section and excellent surface finish. Longer
life and greater torque handling capacity than ordinary clutches.
Clutch/brake material
All components are machined from specification-controlled SAE045 alloy
steel and 6061 tempered aluminum. The input hub, brake hub and one-piece output shaft are
case-hardened to RC 58-60 to a case depth of at least .020. There are
no powdered metal or plastic parts.
Lubrication
Lifetime lubrication with rust-inhibiting grease prevents fretting
corrosion of mating surfaces. Grease fittings can be fitted for severe
applications.
Solenoids
High-quality, industrial grade solenoids with coils completely
encapsulated in rugged steel housings.
Actuators
Delrin AF actuators have high impact strength, high energy
absorption and excellent wear.
