L9

Product catalog summary

Technical Specifications:
The L9 Series motors have specific parameters for displacement, bore, stroke, specific torque, continuous and peak pressure, peak power, continuous and maximum speed, and approximate weight. Key values include a displacement range of 7696 to 10053 cc/rev, bore sizes from 140 to 160 mm, and a stroke of 100 mm. Continuous pressure is set at 250 bar, with peak pressure reaching up to 300 bar. The motors can achieve a peak power of 320 kW and have a continuous speed range of 65 to 85 rpm, with maximum speeds from 110 to 140 rpm. The approximate weight is 700 kg, and the motor oil capacity is 60 liters.

Installation Notes:
Bolt torque settings are specified between 1933 and 2411 Nm for coarse and fine threads, with M30 12.9 bolts suggested. The document advises contacting the SAI Technical Department for higher peak power or continuous speed requirements.

Dimensional Drawings and Spline Data:
Detailed measurements for spline data are provided, including various diameters and tolerances according to DIN 5480 standards.

Bearings Lifetime Calculation:
The permissible loads for bearings are calculated based on the L10 lifetime according to ISO 281:1990. The document provides guidance on selecting pressure, displacement, and speed combinations to estimate bearing lifetime without radial load.

Order Codes:
The order code system is explained, detailing options for displacement, shaft, bearings, other options, distributor, and direction of rotation. Examples include standard configurations and options for high temperature seals and anti-clockwise rotation.
