Hydraulic Motors

Hydraulic Motors

FEATURES:

Ports - 7/8" UN "O" Ring
Roller type Gear Stator
Disc Valve linked to Roller Shaft via Drive Link
Output shaft supported by tapered roller bearings.
High pressure motor seals
Cross port relief required for pressure spikes.
These motors are suitable for continuous operation under rough operating conditions such as high operating pressures, thin oil, or frequent reverse cycling. The tapered roller bearings make the motors suitable for absorbing static and dynamic radial loads. The drive link and balanced disc valve minimise hydraulic and mechanical losses. This design produces motors with high efficiency, even at high pressures, and good starting chracteristics.

Maximum Flow:
65 L/min 17 US gal/min

See NEXT PAGE for motor with
HIGHER maximum pressure and flow.

CUSHION / FREEWHEEL COUPLING FOR HYDRAULIC MOTORS

ESSENTIAL ITEM FOR HYDRAULIC ROTARY CUTTERS

Part No. B8507	Part No. B8508
Standard Anti-clockwise rotation	Optional clockwise rotation for dual motor application
*Bare-Co Patent*

Unique design for hydraulically driven rotary cutters
Allows hydraulic motor to run at ideal 500 / 600 rpm range.
Allows drive through standard agricultural gearbox. 1:1.47 OR 1:1.93 Ratio.
Prevents transmission impact failures by instantly absorbing a massive
1900 Nm (1400 ft lbs) of torque.
Integral freewheel eliminates transmission failure due to cutter disc inertia during hydraulic valve "STOP" condition.
Standard 1 3/8" x 6 spline female / female.
