GS6A

Product catalog summary

Technical Specifications:
The GS Series motors are available in three displacement options: 1700 cc/rev, 2100 cc/rev, and 2500 cc/rev. The bore sizes are 82 mm, 92 mm, and 100 mm respectively, with a stroke of 64 mm. Specific torque values are 26.90 Nm/bar, 33.86 Nm/bar, and 40.00 Nm/bar. Continuous pressure is rated at 300 bar for the first two models and 250 bar for the 2500 cc model, with peak pressures of 450 bar, 400 bar, and 350 bar respectively. Peak power is 300 kW, with continuous speeds of 400 rpm for the first two models and 300 rpm for the 2500 cc model. Maximum speeds are 600 rpm, 575 rpm, and 500 rpm respectively. The approximate weight is 291 kg, and the motor oil capacity is 25 liters. Maximum casing pressure is 5 bar continuous and 15 bar peak, with admissible temperatures ranging from -20°C to +80°C.

Installation Notes:
Bolt torque settings are specified between 561.0 to 697.0 Nm for coarse threads and 586.0 to 736.0 Nm for fine threads, with M20 bolts of grade 12.9 recommended.

Shaft Options:
Available shaft options include splined (6/12” PITCH BS3550), internally splined (80x3x25 DIN5480), and cylindrical types.

Spline Data:
Detailed dimensions for splines are provided, including various diameter measurements and tolerances.

Motor Bearing Lifetime:
Bearings lifetime is calculated according to ISO 281:1990, with permissible loads for different lifetime steps (L10). Graphs are provided to select combinations of pressure, displacement, and speed to identify bearing lifetime without radial load.

Maximum Permitted Radial Load:
Graphs are provided to identify the maximum radial load allowed based on the required torque.

Order Codes:
The order code structure is explained with examples, detailing displacement, shaft options, bearings, other options, distributor options, and direction of rotation.
