Highlights

Roller gear set hydraulic motors with pressure compensated valve disc and tapered roller bearing support
The ARS series can withstand large radial and axial forces

• Low-speed hydraulic motor with rollers in the gear ring (Geroller rotor set) and disc distribution valve for open and closed circuit, suitable for continuous duty under difficult operating conditions thanks to reduced friction by hydrodynamic lubrication of the rollers in the gear ring durability and better efficiency, even at high continuous pressure

• Driven from the output shaft by Oldham coupling poppet with optimized geometry ensures minimization of the hydraulic and mechanical losses

• Output shaft runs in tapered roller bearings, resulting in high radial and axial loads are possible

• Double shaft seal for protection of the main seal from dust and other contaminants

• Integrated non-return valves (standard) for reduction of case pressure with closed drain port

• External drain port to relieve the pressure of the housing

• Very compact size and high power density

• Excellent starting performance and smooth running at low rpm

Variants
ARS – Standard version with side ports (40×8 mm)
ARSW – version with the recessed mounting flange for wheel hub / winch drum assembly (radial load in the middle between the two tapered roller bearings)
ARF – Version with negative safety brake (. Opening pressure 22 ÷ 27 bar, max pressure 200 bar, static brake torque 350 Nm)

Options
FP – negative safety brake(opening pressure 22 ÷ 25 bar, max pressure 160 bar, static brake torque 370 Nm, maximum speed 350 rev. / Min.) – Drain line required
TAC – for speedometer connection (M22x1, 5 Ø9×3)
TAC-E – electronic speedometer with hole M8x1 for speed sensor (max. pressure 20 bar housing)
BFL – ports in the valve terminal type (67×29 mm – M8) for base BFL1

Port Mounted Valves
AF – Shuttle valve to control the brake
VAF 08-D – shock valve
VAAF 31 – shock valve with anti-cavitation
VAF 08-D/AF – shock valve with shuttle valve to control the brake
VCD 08-S/AF – load holding valve single acting with shuttle valve to control the brake
VCR1 08-D/AF – load holding valve with double acting shuttle valve to control the brake
VCR1 08-D/AF-LDP – load holding valve with double acting shuttle valve to control the brake – with shock valve LDP
