ROTAMAAC<\/strong> products cover a wide range of hydraulic rotary actuators capable of delivering high torques.
They are widely used in the industrial sector, particularly in steelworks, materials handling, ports, ships, etc.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Technical details:<\/span><\/h1><\/h2><\/div>

The rack-and-pinion design is used in single-acting or double-acting versions, depending on the torque range required. The standard single cylinder can be doubled to a twin configuration, operating in opposition, thus doubling torque. <\/span>Standard rotation angles are usually 180\u00b0 or 280\u00b0, but other angles are available on request.<\/span><\/p>\n

Here is an example of the characteristics of this type of cylinder:<\/p>\n<\/div><\/div><\/div>

Torque range description:<\/h3>\n

Based on our technical experience, we have drawn up a table to help our customers select the size of cylinders they need. This table shows the approximate sizes of rotary cylinders, with torque ratings up to 37,000 daN bar.<\/p>\n<\/div><\/div><\/div>

Please note that this information is intended as a guide only. The precise calculation of the dimensions and forces applied to the hydraulic cylinders must be carried out according to your application. <\/span><\/p>\n

Several characteristics can be defined and adapted to the final context, including :<\/strong><\/p>\n

\n

The integration of end-of-stroke cushioning systems, with adjustment options<\/p>\n

Desired angle of rotation<\/p>\n

Shaft sealing type (lip seal (N) or bushings (H))<\/p>\n

Hydraulic ports (SAE, BSPP, etc.)<\/p>\n

The type of shaft coupling, whether splined or keyed<\/p>\n

The type of oil used, which has an impact on seal technologies<\/p>\n

Possible integration of a rotary encoder for shaft positioning<\/p>\n

Other elements to be defined together…<\/p>\n<\/blockquote>\n<\/div><\/div><\/div><\/div><\/div>
