Motors – Piston

Gold Cup ®

• Compact fixed or variable • Precision barrel bearing, a distinc-
displacement design tive Parker Denison Hydraulics
• Visual indicator is standard on feature for over 30 years – permits
variable motors high speeds, high pressure and
provides long life
• Reverse compensator option for
high inertia loads • One piece stroking vane/cam
means no lost motion, zero
• Versatile controls – can be located backlash, better control, and
on either side of pump or motor for no linkages to wear out
maximum freedom of design • Conforms to SAE mounting
• Dampened low inertia rocker cam – standards. These products
more stable, quieter and faster are qualified to meet Military
than other designs specifications MIL-P-17869A
and MIL-S-901-C Grade A
