Steering gears

The Scan Steering solution is your guarantee for a reliable and high-performance steering gear system designed specifically for commercial vessels. Our steering gear is available with multiple rudder stock mounting options and cylinder configurations, including ram type steering gear, making it ideal for compact steering compartments on ships such as fishing vessels, workboats, luxury yachts, and small ferries — all requiring large rudder angles and precise control.

Since 1962, AS SCAN has manufactured and delivered more than 1,500 steering gear ship systems globally. Our steering gear systems can be delivered as complete turnkey solutions, including hydraulic ram type steering gear, pump units, control systems, and alarms – fully integrated and classification-approved.

Compact and Flexible Steering Gear System for Ships

Scan Steering is a space-saving and modular steering gear system, ideal for both single- and twin-rudder ships. Our engineers provide detailed installation drawings and offer system customisation to ensure optimal fit and function for your vessel. Whether your ship requires a standard or tailored solution, we ensure simple installation and operational efficiency.

Built-in redundancy in each steering gear system guarantees continued operation during critical situations. All Scan Steering solutions are built using high-quality, standardised components from trusted manufacturers – ensuring easy spare part replacement and minimising costly downtime when your ship returns to its home port.

AS SCAN also offers global service support and maintains a wide stock of spare parts for all types of steering gear.

Rudder carrier bearings for steering gear ship systems

A vital part of our steering gear ship offering is the Scan Steering rudder carrier bearing, designed to support and guide the rudder, enabling smooth rotation of the rudder stock. The bearing features a double-row spherical roller bearing mounted in a housing integrated into the steering gear baseplate. This allows for easy installation, precise alignment, and low maintenance.
