If you're serious about maintaining your RC truggy's performance or building a high-specification racing platform, these bearings are an essential spare parts investment that will keep your vehicle running smoothly lap after lap.
The flanged design combined with rubber sealing technology represents the industry-standard approach to bearing protection, offering superior sealing compared to open bearings whilst remaining responsive to the demands of precision racing. These bearings are trusted by competitive RC racers and serious hobbyists across the UK who refuse to compromise on component quality. Stock a set of these replacement bearings and ensure your RC racing platform maintains optimal performance throughout the racing season.
Key Features
- 8x14x4mm Precision Dimensions — These bearings are manufactured to exact specifications with inner bore diameter of 8mm, outer diameter of 14mm, and width of 4mm, ensuring perfect fitment and compatibility with your Losi racing platform without modification or forcing.
- Flanged Design — The integrated flanges on these bearings provide enhanced structural support and positioning within the suspension and drivetrain components, preventing lateral movement and maintaining precise alignment critical for high-speed racing performance.
- Rubber Sealed Construction — Rubber seals on both sides of each bearing create an effective barrier against moisture, dirt, sand and debris ingress, extending bearing life significantly compared to open bearing designs and protecting internal races from environmental contamination during outdoor racing.
- Pack of Four Units — This set includes four individual bearings, providing sufficient quantity for typical suspension and drivetrain applications on RC truggy platforms like the TLR 8IGHT-XT and 8IGHT-XTE models.
- Losi Original Equipment — Manufactured by Losi, the recognised leader in 1/8 scale RC racing platforms, these are genuine OEM components engineered to the exact tolerances and specifications required for optimal performance in competition and recreational racing environments.
- Competition-Grade Reliability — These bearings are the same components supplied with new Losi racing kits and utilised by competitive RC racers throughout the UK and internationally, providing proven performance and reliability in demanding racing conditions.
Technical Performance
The Losi 8x14x4 Flanged Rubber Sealed Ball Bearings represent precision engineering at the component level, delivering the low-friction rotation essential for high-performance RC racing platforms. The 8mm inner diameter and 14mm outer diameter combination accommodates the suspension and drivetrain requirements of 1/8 scale racing trucks whilst the 4mm width provides adequate material thickness for load distribution during aggressive acceleration, cornering and braking events. The rubber sealing technology employed on these bearings creates a dual-sided protective barrier without significantly increasing rotational resistance, maintaining the responsiveness and speed delivery that competitive racers demand. The flanged construction integrates seamlessly with Losi's suspension geometry and drivetrain architecture, ensuring these bearings function as precision components rather than universal substitutes. Built to withstand repeated thermal cycling, moisture exposure and the mechanical stresses of high-speed racing, these bearings embody the engineering principles that have made Losi one of the most respected manufacturers of competition-grade RC racing vehicles in the world.

Frequently Asked Questions
- Which RC vehicles do these Losi ball bearings fit? — These 8x14x4 flanged rubber sealed ball bearings are designed for the TLR 1/8 8IGHT-XT and 8IGHT-XTE 4WD Nitro and Electric truggy race kits. If you own either of these competition-grade RC racing platforms, these bearings are direct replacement components compatible with your vehicle's suspension and drivetrain systems.
- Why should I replace my bearings with genuine Losi parts rather than budget alternatives? — Genuine Losi bearings are engineered to precise tolerances and specifications developed through years of competitive racing experience. Using authentic OEM components ensures optimal fit, consistent performance, and long-term reliability. Budget aftermarket bearings often have looser tolerances that introduce play into suspension and drivetrain systems, degrading handling precision and increasing wear on other components—ultimately costing more in replacement parts over time.
- What is the advantage of flanged bearings compared to standard ball bearings? — The flanged design incorporates integrated shoulders that prevent lateral movement of the bearing within its housing, maintaining precise alignment essential for high-speed racing performance. This design eliminates the need for external spacers or shims in many applications, simplifying assembly whilst improving suspension geometry consistency across racing sessions.
- How do rubber seals extend bearing life in outdoor RC racing? — Rubber seals create an effective barrier preventing moisture, dirt, sand and road debris from contaminating the internal races and ball elements within the bearing. During outdoor RC racing in typical UK weather conditions—including rain, mud and dust—sealed bearings maintain internal cleanliness far longer than open bearings, reducing friction increase and bearing wear, ultimately extending service life significantly.
- How often should I replace these bearings during competitive racing? — Bearing replacement frequency depends on racing intensity, environmental conditions and maintenance practices. Competitive racers typically inspect bearings after every 3-5 racing days of intensive use, replacing any bearing showing visible damage, excessive play or rotational resistance. Regular maintenance inspections extend bearing life and prevent sudden failures during racing events.
- Are these bearings suitable for beginners new to RC racing? — Whilst these are genuine Losi components of excellent quality, they are replacement parts rather than beginner entry-level products. These bearings are most appropriate for owners of TLR 8IGHT-XT or 8IGHT-XTE racing kits who understand basic RC maintenance and replacement procedures. If you're new to RC racing, we recommend purchasing a complete ready-to-run or race kit platform rather than individual components, then consulting our experienced team for guidance on maintenance.
