TD1.5

Product catalog summary

Overview: This provisional leaflet provides technical specifications and operational guidelines for the TD1.5 and TV1.5 hydraulic motors. The document is subject to change without prior notice and all data are based on existing projects.

Specifications:

Equivalent Displacement: Ranges from 241 cc/rev to 405 cc/rev depending on the model.
Bore and Stroke: Bore sizes are 37 mm, 44 mm, and 48 mm with a stroke of 32 mm.
Specific Torque: Varies from 3.82 Nm/bar to 6.45 Nm/bar.
Pressure Ratings: Continuous pressure is 350 bar, peak pressure ranges from 400 to 450 bar.
Power and Speed: Peak power is 110 kW, with continuous speed ranging from 650 to 1800 rpm and maximum speed from 800 to 2300 rpm.
Weight and Oil Capacity: Approximate weight is 55 kg with a motor oil capacity of 0.8 liters.

Operational Guidelines:

Continuous or average working pressure should be selected based on bearing lifetime. For calculations, contact the SAI Technical Department.
For higher casing pressure or continuous speed, consult the SAI Technical Department.

Installation Notes:

Bolt Torque Setting: Coarse 116-143 Nm, Fine 121-150 Nm. Suggested bolt type is M12 12.9.
Zero displacement is available on request.

Dimensional Drawings and Shaft Options:

Standard and internally splined shaft options are available with detailed dimensional specifications provided.

Bearing Life:

The document includes a chart for estimating bearing life based on pressure-speed-torque combinations. L10 lifetime is calculated according to ISO 281:1990.

Order Codes:

Displacement, distributor, accessories, shaft options, and sensor positions are coded for ordering. Examples include TD1.5 400-100 9G D47D and TV1.5 400-100 9G D47V.

Recommendations:

Sensor positions #2 are not recommended due to susceptibility to damage.
