Product catalog summary

Specifications:
The GS Series motors are available in various displacements ranging from 400 to 1100 cc/rev. The bore sizes vary from 42 mm to 70 mm, with a consistent stroke of 58 mm. Specific torque values range from 6.27 Nm/bar to 17.40 Nm/bar. Continuous pressure is maintained at 300 bar for most models, with peak pressures ranging from 350 to 450 bar. The motors have a peak power of 150 kW and continuous speeds from 400 to 600 rpm, with maximum speeds up to 830 rpm. The approximate weight of the unit is 116 kg, with a motor oil capacity of 7 liters.

Procedures and Recommendations:
Continuous or average working pressure should be selected considering the bearing lifetime. For higher peak power or continuous speed requirements, contact the SAI Technical Department. Installation notes include bolt torque settings for different bolt types, with suggested types being M18 12.9.

Dimensional Drawings and Shaft Options:
The catalogue provides detailed dimensional drawings and various shaft options, including splined, internally splined, cylindrical, and tapered types. Preferred types are indicated for ease of selection.

Spline Data:
Detailed measurements for different spline standards (UNI 221, DIN 5480, DIN 5482) are provided, including tolerances and dimensions for each type.

Motor Bearing Lifetime:
A graph is provided to calculate the bearing lifetime (L10) based on unit speed and pressure. The L10 value can be converted to hours using a specific formula. For specific applications, contact the technical department.

Maximum Permitted Radial Load:
Graph 2 helps identify the maximum radial load allowed on the motor shaft based on the required torque. For lifetime calculations with radial load, use the VITA software or contact SAI.

Order Codes:
The catalogue includes a detailed explanation of order codes, specifying displacement, shaft options, bearings, other options, distributor options, and direction of rotation. Examples are provided for standard and optional configurations.
