The CB/T 290-95 Marine Chain Wheel is a heavy-duty anchor chain guiding device designed for marine anchoring systems. Installed along the anchor chain path, it supports and guides the chain as it moves between anchoring components, helping maintain proper chain alignment and smooth movement. The specially designed grooved wheel provides stable support for the anchor chain while reducing unnecessary friction and wear during anchor handling. The rotating wheel follows the movement of the chain, making it suitable for anchoring systems where the chain direction needs to be guided or changed.
Manufactured according to CB/T 290-95, the marine chain wheel is available for anchor chain diameters from 12.5 mm to 68 mm. Its robust supporting structure, durable wheel and shaft assembly, and marine-grade protective coating make it suitable for demanding shipboard environments.
Boomarine supplies CB/T 290-95 chain wheels in multiple sizes and can also provide customized manufacturing according to vessel drawings and project requirements.

Features of CB/T 290-95 Marine Chain Wheel
1. Smooth Anchor Chain Guidance
The grooved chain wheel supports the anchor chain and helps guide it smoothly through the anchoring system, reducing unnecessary lateral movement.
2. Reduced Chain Friction and Wear
The rotating wheel reduces sliding contact between the anchor chain and fixed supporting structures, helping minimize friction and chain wear.
3. Heavy-Duty Construction
A robust steel support frame, shaft and chain wheel provide reliable mechanical strength for demanding marine anchoring applications.
4. Wide Size Range
CB/T 290-95 chain wheels are available for anchor chains ranging from 12.5 mm to 68 mm, covering a broad range of vessel sizes.
5. Stable Chain Alignment
The wheel groove helps maintain the correct chain position during anchor handling, improving the stability of the anchor chain path.
6. Marine Corrosion Protection
Marine-grade paint and customized coating systems can be applied to protect the equipment against seawater, salt spray and humid marine conditions.
7. Simple Structure & Maintenance
The straightforward wheel, shaft and support-frame construction facilitates inspection, lubrication and routine maintenance.
Main Applications
The CB/T 290-95 Marine Chain Wheel is suitable for anchoring systems on:
- Bulk carriers
- Container ships
- General cargo vessels
- Tankers
- Tugboats
- Workboats
- Barges
- Engineering vessels
- Offshore support vessels
- Marine platforms
- Other commercial vessels
It can be used as part of the anchor chain arrangement where smooth chain guidance, directional control and mechanical support are required.

How Does a Marine Chain Wheel Work?
A marine chain wheel acts as a supporting and guiding component for the anchor chain.
As the anchor chain moves during paying out or heaving operations, it passes over the grooved wheel. The wheel rotates together with the moving chain, providing rolling contact instead of allowing the chain to drag continuously across a fixed steel surface.
This helps:
- Guide the anchor chain in the required direction
- Maintain proper chain alignment
- Reduce sliding friction
- Minimize localized chain wear
- Support smooth anchor handling
Depending on the vessel’s anchor arrangement, the chain wheel can be positioned where additional chain support or directional guidance is required.
