Key Features
- Genuine Blade Component — This bearing is manufactured by Blade and engineered specifically for the Blade 450 X helicopter, ensuring perfect compatibility and reliable performance in your aircraft.
- Precision Engineering — The 3x7x3mm specification delivers exact dimensional tolerances required for smooth rotation and minimal play, which is essential for maintaining flight stability and control responsiveness.
- Durable Construction — Built to withstand the continuous rotational loads and vibrations generated during RC helicopter flight, this bearing provides extended service life when properly maintained.
- Essential Maintenance Component — Bearings naturally wear over time due to friction and loads, making this spare essential for any serious Blade 450 X operator who wants to keep their helicopter in peak condition.
- Easy Installation — As a direct genuine replacement part, this bearing installs seamlessly into your Blade 450 X without requiring modification or adaptation, saving time and ensuring correct fitment.
- Affordable Spares Solution — Replacing individual worn bearings is far more cost-effective than replacing entire assemblies, making this spare part a smart choice for budget-conscious RC pilots.
Technical Performance
The BLH 3x7x3 bearing represents precision engineering at the component level for the Blade 450 X helicopter platform. With its 3mm inner diameter, 7mm outer diameter and 3mm width, this bearing is engineered to exact specifications that ensure smooth, low-friction rotation within the helicopter's drivetrain and mechanical systems. Blade has designed this component to tolerate the specific loads, speeds and vibration profiles generated by the Blade 450 X's flybarless head system, feathering control mechanisms and tail drive components. The bearing's construction delivers minimal rotational drag, which is critical for maintaining the precise control authority and mechanical efficiency that RC helicopter pilots depend upon. Over time, through normal flight operations, bearings accumulate microscopic wear on their rolling elements and races. When this occurs, you may notice increased mechanical noise, slight loss of control precision or increased friction resistance. Replacing worn bearings with genuine Blade spares like this one restores your helicopter to its original performance characteristics. The 3x7x3 specification is used in multiple locations throughout the Blade 450 X airframe, meaning having spare bearings on hand allows you to perform preventative maintenance or address wear across different mechanical systems. Quality bearings are essential to the longevity and reliability of your RC helicopter investment, and using genuine Blade components ensures you're maintaining your aircraft with parts engineered and tested by the manufacturer themselves.

Frequently Asked Questions
- What is the BLH 3x7x3 bearing used for in the Blade 450 X? — This bearing is a precision component used in multiple locations throughout the Blade 450 X helicopter's drivetrain and mechanical systems. Its exact applications depend on your specific helicopter configuration, so consulting your Blade 450 X manual will show you precisely where this 3x7x3 specification is fitted and when replacement is recommended.
- How do I know if my Blade 450 X bearing needs replacing? — Signs that bearings need replacement include increased mechanical noise during operation, visible play or looseness in mechanical linkages, reduced control smoothness, or grinding sensations when manually rotating components by hand. If you're unsure, consult your Blade 450 X manual or contact our expert team at RC Model Shop, and they can advise you on the condition of your specific aircraft.
- Is this bearing compatible with other Blade helicopter models? — This bearing is designed specifically for the Blade 450 X. While similar bearing sizes may be used across other Blade models, you should always verify compatibility by checking your helicopter's manual or contacting our team before purchasing. Using non-compatible spares can result in incorrect fitment and potential mechanical issues.

We maintain large inventories on the shelf and offer fast UK delivery options, including next-day shipping in many cases, so you can get back in the air quickly.
- How often should I replace bearings on my Blade 450 X? — The service life of bearings depends on flight frequency, flying style and maintenance practices. Regular visual and manual inspection during routine maintenance helps identify wear early. Some pilots replace bearings preventatively as part of seasonal servicing, while others only replace them when wear becomes noticeable. Your Blade manual offers guidance on recommended service intervals.
- Can I order multiple bearings at once? — Yes, many RC pilots and engineers stock multiple spare bearings for their helicopters. You can purchase as many of this bearing as you need. Purchasing spares now ensures you have them available when needed, avoiding delays if you need replacements during the flying season.
