TV2.5

Product catalog summary

Overview: This provisional leaflet provides technical specifications for the TD2.5 and TV2.5 hydraulic motors, highlighting their dual and variable displacement capabilities. The document is subject to change without prior notice.

Specifications:

Displacement: Ranges from 352 to 792 cc/rev depending on the model.
Bore and Stroke: Bore sizes range from 40 mm to 60 mm, with a consistent stroke of 40 mm.
Torque and Pressure: Specific torque ranges from 5.60 to 12.60 Nm/bar, with continuous pressure up to 400 bar and peak pressure up to 450 bar.
Speed: Continuous speed ranges from 350 to 700 rpm, with maximum speeds from 450 to 900 rpm.
Weight and Oil Capacity: Approximate weight is 90 kg with a motor oil capacity of 0.8 liters.

Installation and Operation:

Bolt Torque: Suggested torque settings are 116-143 Nm for coarse and 121-150 Nm for fine threads.
Temperature Range: Operates between -20°C and +80°C.
Pressure and Speed Adjustments: For higher casing pressure or continuous speed, contact the SAI Technical Department.

Dimensional Drawings and Shaft Options: The document includes detailed dimensional drawings and spline data for both external and internal splined shaft options.

Bearing Life: Bearing life is calculated according to ISO 281:1990, with L10 lifetime expressed in millions of revolutions and convertible to hours.

Order Codes: The leaflet provides a detailed breakdown of order codes for different configurations, including displacement, distributor options, shaft options, and sensor positions.

Recommendations: Sensor positions #2 are not recommended due to susceptibility to damage, which may affect motor operation.
