Linearni mehanski cilindar tip 2 kratki, 300 mm, 24 V

This Raymarine actuator (reference M81133) is designed for sailboats and motorboats that require significant thrust force for their steering system.

The standard Type 2 short model has a 300 mm stroke, allowing it to maintain a compact installation footprint while delivering high mechanical performance.

This mechanical linear actuator operates exclusively with a 24V supply voltage.

It integrates seamlessly with Raymarine autopilot computers, including the ACU or SPX series, to ensure fast and highly accurate helm response.

Installation requires precise alignment. The pushrod must be strictly perpendicular to the rudder stock when the rudder is in the central position. The allowed alignment variation is less than 5 degrees.

This mechanical actuator acts directly on the boat's tiller sector or rudder arm.

The actuator alone weighs 7.72 kg. Due to this weight and the thrust force exerted, it must be mounted on a very solid structural base.

Raymarine recommends a full service by an authorized dealer every 1,000 hours of use or every 2 years, whichever comes first.

For a 24V installation with cable length up to 3 meters, a 4 mm² (12 AWG) cross-section is required to prevent voltage drops.

If the power cable length reaches 5 meters, the manufacturer's specifications require the use of a 6 mm² (10 AWG) cable.

For a distance up to 10 meters at 24V, you must use cables with a cross-section of 10 mm² (8 AWG).

To avoid electromagnetic interference, the actuator must be installed at least 1 meter (3 feet) away from any equipment or cables transmitting radio signals, such as a VHF.

Yes, for HF radios (SSB), the minimum separation distance from the hydraulic ram must be increased to 2 metres (7 feet).

No, it is strongly recommended to power the equipment from a dedicated battery. Voltage drops during engine start (below 10V) could cause the autopilot system to reset.

No, reference M81133 is specifically designed for 24V systems. If you have a 12V network, you will need to use the corresponding actuator reference (M81131).

The actuator must be installed more than 2 meters (7 feet) from the radar beam path to avoid any electromagnetic interference.

Unlike type 1 models, the type 2 actuator offers superior robustness and greater thrust force, making it suitable for heavier and more demanding steering systems.

Yes, the industrial design of this hydraulic ram generates very high thrust forces. It therefore requires mounting on a structure capable of absorbing heavy loads. If in doubt, consult the manufacturer of your steering system.

It is not recommended to cut or splice the cables specified by Raymarine, as this may compromise electromagnetic performance (EMC), unless the procedure is explicitly detailed in the installation manual.

For a very long installation, up to 16 meters at 24V, it is essential to use a thick cable, 16 mm² (6 AWG), to ensure stable power supply to the actuator.
