HoBao H2 EX10 Ball Bearing 5x8mm 4-Pack H224064

Overview

The HoBao H2 / EX10 Ball Bearing 5x8mm (4) H224064 is an essential replacement and upgrade component for owners of HoBao RC cars in the UK. These precision ball bearings are specifically engineered to fit the HoBao Hyper 10SC 2.0 Electric Truck and related models, providing smooth rotation and reduced friction across critical drivetrain components. Whether you're maintaining your RC buggy, preparing for competitive racing, or upgrading worn bearings on your electric RC car, these OEM-specification bearings deliver the reliability and performance that serious RC enthusiasts demand.

Ball bearings are fundamental to RC car performance, acting as the foundation for smooth wheel rotation, gearbox operation, and differential function. When bearings wear or become damaged through regular use, they introduce play, noise, and drag that directly impact your RC vehicle's speed, handling precision, and overall driving experience. The HoBao H2 / EX10 5x8mm bearings are purpose-designed to restore your RC car to factory specifications, ensuring optimal performance whether you're bashing on weekends or competing at your local RC track.

Available now at RC Model Shop, these genuine HoBao bearings represent quality engineering and compatibility assurance. UK RC enthusiasts trust HoBao components for their durability and precise manufacturing tolerances, which is why these bearings have become a staple in workshop toolkits and pit boxes across the country.

Key Features

• 5x8mm bore and outer diameter specification — These bearings are engineered to exact HoBao specifications, ensuring perfect fit and function in designated bearing housings throughout the H2 and EX10 chassis.
• Pack of four bearings — You receive four precision ball bearings in this pack, providing enough components to replace bearings in multiple locations or maintain spares for track days and competitive events.
• OEM HoBao part — As an officially manufactured HoBao component, these bearings meet the original equipment manufacturer's exacting standards for tolerance, material quality, and performance characteristics.
• Precision ball bearing construction — Ball bearings distribute load more efficiently than sleeve bearings, reducing friction and heat generation during high-speed driving and extended running sessions.
• Universal compatibility across HoBao models — These bearings work across multiple HoBao Hyper 10SC 2.0 variants including RTR and ARR configurations with different body colours and specifications.
• Essential maintenance component — Regular bearing replacement keeps your RC car running smoothly and helps prevent premature wear on gearboxes, differentials, and drive shafts.

Technical Performance

The HoBao H2 / EX10 Ball Bearing 5x8mm represents precision engineering at the component level. These ball bearings feature carefully selected steel construction with smooth internal races that minimise friction and heat generation under load. The 5x8mm specification indicates an inner bore of 5mm and an outer diameter of 8mm, dimensions that have been engineered to fit specific locations within the HoBao H2 and EX10 chassis architecture. Ball bearing design offers superior performance compared to sleeve or bush-type bearings, particularly in applications requiring high-speed rotation and consistent load distribution. The smooth operation provided by these bearings directly translates to reduced power loss from friction, meaning your electric RC car maintains better speed consistency and delivers more responsive handling throughout an extended driving session. For RC enthusiasts running brushless RC vehicles, component-level efficiency improvements like quality bearings contribute to overall system performance and longevity. The construction quality of HoBao bearings reflects the manufacturer's commitment to reliability, making them an excellent choice for serious RC hobbyists in the UK who demand genuine parts that perform consistently across competitive and recreational driving scenarios.

Frequently Asked Questions

• Which HoBao models are compatible with these 5x8mm ball bearings? — These bearings are specifically engineered for the HoBao Hyper 10SC 2.0 Electric Truck family, including the HB-SC2E-C60BRG RTR with orange and black body, HB-SC2E-C60BUW RTR with blue and white body, HB-SC2E ARR with clear body, HB-SC2E-C60BU RTR with blue body, and HB-SC2E-C60DG RTR with grey body. Additionally, they are compatible with the HoBao H2 and EX10 model ranges.
• How often should I replace ball bearings in my RC car? — Ball bearing replacement intervals depend on usage intensity and driving conditions. For casual weekend bashers, annual inspection and replacement as needed is typical. For competitive racers running multiple heats, more frequent bearing changes may be warranted. Noticeable signs that bearings need replacement include grinding sounds, visible play when the axles are moved by hand, or reduced wheel spin when your RC car is held up and spun freely.
• Are these genuine OEM HoBao parts? — Yes, the H224064 is an official HoBao manufactured component and bearing specification. Purchasing genuine OEM parts ensures compatibility, reliability, and performance consistency compared to aftermarket alternatives.
• What is the difference between ball bearings and other bearing types in RC cars? — Ball bearings use multiple hardened steel balls to distribute loads evenly, providing superior performance, lower friction, and better speed retention compared to sleeve bearings or bushings. Ball bearings are the preferred choice for high-performance RC driving, especially in electric vehicles where efficiency directly impacts runtime and responsiveness.
• Can I install these bearings myself? — Yes, HoBao bearing installation is straightforward for experienced RC enthusiasts with basic mechanical knowledge. However, if you're unfamiliar with RC car maintenance, the team at RC Model Shop can provide guidance or recommend professional installation services through our network of specialist RC technicians.
• Do these bearings require any special maintenance? — HoBao ball bearings benefit from occasional cleaning to remove dirt and debris, particularly if driven in dusty or sandy conditions. Some enthusiasts apply light bearing lubricant, though the bearings function well without additional lubrication in most UK driving conditions.
