B&G Wind Speed Bearing, Fits WS310/WS320/WS700 and 508/608/213/496 Sensors

Overview

The B&G 213-10-038 is a replacement wind speed bearing for B&G masthead wind sensors. It restores smooth cup rotation when the original bearing starts to feel rough, bind, or develop play, which can show up as low wind speed readings, slow response in light air, or noisy data when the boat pitches and rolls.

This part services the wind speed side of the sensor (the anemometer cups). It is not the wind angle bearing, and it is not a complete masthead unit.

Key features

• Replacement bearing for the wind speed (cup) assembly on B&G masthead wind sensors
• Compatible with WS310 and WS320 wind sensors
• Also used across WS700 series, 608, 508, 213, and 496 wind sensors
• Helps correct wind speed issues caused by a worn, sticky, or noisy cup bearing
• Service part that lets you refresh the masthead unit without replacing the full wind sensor

Compatibility and fit

This bearing is used in several B&G wind sensor families, including WS310, WS320, WS700 series, 608, 508, 213, and 496. Confirm your masthead unit model before ordering, especially if the sensor has been on the mast for many seasons or the boat has mixed generations of B&G instruments.

If your wind sensor still reports wind angle correctly but wind speed is erratic or slow to respond, the wind speed bearing is a common wear point to address along with inspecting the cups for cracks, UV damage, or looseness.

Installation and setup

Replacing a masthead bearing is usually a small-mechanics job, but it does require safe access to the masthead. Plan the work for dockside or calm conditions, and secure tools and small parts so nothing is dropped overboard.

After installation, the cups should spin freely by hand without grinding or wobble. Once back online, verify wind speed response at low apparent wind and compare against expected readings under steady conditions.

Use cases on board

This bearing is a good match for sailors who rely on accurate wind speed for trim and performance and have a masthead unit that has begun to stick or feel rough after seasons of salt exposure and constant rotation. It is also a sensible spare for offshore runs where a simple wear part can stop wind speed data from becoming unreliable mid-passage.

Maintenance and care

Rinse the masthead sensor with fresh water during routine washdowns and avoid blasting the unit with high-pressure spray. Periodic inspection of the cups and checking for free rotation helps catch bearing wear before it turns into inconsistent wind speed data.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
