Overview
The ARRMA Ball Bearing 7x11x3mm (2RS) (4pcs) Z-ARA610053 is an essential spare parts pack for RC enthusiasts and competitive racers across the UK. These precision-engineered ball bearings are designed as direct replacement components for a wide range of ARRMA RC vehicles, from the popular 1/16 scale Grom series through to larger models. Whether you're maintaining your RC car UK collection, undertaking routine maintenance, or replacing worn bearings after intensive bashing sessions, this four-piece bearing set offers exceptional value and reliability. ARRMA is renowned for manufacturing high-quality replacement parts that meet original equipment specifications, ensuring your RC vehicle performs at its best.
Ball bearings are critical components in any RC car, truck, or buggy, as they enable smooth rotation of wheels, drive shafts, and other moving parts. Over time, through regular use, exposure to dust, moisture, and the general wear and tear of RC racing and off-road driving, bearings can become worn or damaged. That's why having quality replacement bearings in your spares box is essential for any serious RC hobbyist. The ARRMA Ball Bearing 7x11x3mm (2RS) features double rubber shields for enhanced protection, making these bearings suitable for use in various driving conditions, whether you're running on-road, off-road, in dry conditions, or in damp environments typical of UK outdoor RC racing venues.
This pack is compatible with numerous ARRMA models, including the 1/16 GORGON GROM in multiple colours, the 1/18 GRANITE GROM MEGA 380, the 1/16 Mini Kraton 3S, the 1/16 MOJAVE GROM 223S BLX, the 1/16 QUAKE GROM, and the 1/14 TYPHON GROM series. The compatibility list demonstrates the versatility and widespread application of these bearings across ARRMA's popular Grom range and other models, making them an excellent addition to your RC spares collection.
Key Features
- Double Protective Rubber Shields (2RS) — The 2RS designation means these bearings feature double rubber seals on each side, providing enhanced protection against dust, dirt, water, and other contaminants that can compromise bearing performance and longevity, particularly important for UK weather conditions and outdoor RC racing.
- Premium Ball-Raced Construction — These bearings utilise high-quality ball-race technology that ensures ultra-smooth operation in all driving conditions, whether you're performing high-speed runs, technical manoeuvres, or intensive off-road bashing with your RC car.
- Precision Manufactured Tolerances — Each bearing is manufactured to consistent and precise tolerances, ensuring fast and easy installation without requiring modifications, and guaranteeing consistent performance across all four bearings in the pack.
- Secure and Safe Assembly — The consistent manufacturing tolerances ensure that these bearings fit securely within your RC vehicle's bearing housings, providing stable and reliable operation without play or movement that could affect handling and performance.
- Four-Piece Pack — The set contains four individual rubber-shielded ball bearings, providing enough replacements to service multiple bearing locations or to keep as emergency spares for race days and serious RC sessions.
- Authorised ARRMA Genuine Parts — These are genuine ARRMA original equipment parts, not aftermarket alternatives, ensuring they meet ARRMA's exacting standards and will integrate seamlessly with your ARRMA RC vehicle.
Technical Performance
The ARRMA Ball Bearing 7x11x3mm (2RS) represents the engineering standards expected from ARRMA, one of the leading manufacturers of ready to run RC vehicles and replacement parts. With dimensions of 7mm inner diameter, 11mm outer diameter, and 3mm width, these bearings are specifically engineered to fit the bearing housings found across ARRMA's extensive model range. The 2RS designation refers to the double rubber seal configuration, where rubber shields are pressed into both sides of the bearing assembly. This design provides superior protection compared to unsealed or single-sealed alternatives, making these bearings particularly suitable for use in varying UK weather conditions. The rubber shields deflect water, mud, sand, and dust away from the ball races whilst still maintaining smooth rotational characteristics. The ball-race construction utilises hardened steel balls that roll within precision-ground races, creating minimal friction and enabling the wheel or shaft to spin freely even during high-speed runs or under load during acceleration and cornering. The consistent manufacturing tolerances mean that all four bearings in the pack perform identically, preventing uneven wear patterns and ensuring balanced handling across your RC vehicle. Whether you're operating a brushless RC monster truck, a competition-grade RC buggy, or any other ARRMA ready to run model, these bearings will maintain the performance and reliability expected from your investment in quality RC equipment.

Frequently Asked Questions
- Are these bearings suitable for all types of RC driving? — Yes, these ARRMA ball bearings are designed for all-conditions operation including on-road driving, off-road bashing, wet weather driving, and competitive racing. The double rubber shields protect the ball races from contamination in all environments, making them versatile replacements for any ARRMA RC car UK enthusiast.
- How often should I replace my RC bearings? — Bearing replacement frequency depends on usage intensity, driving conditions, and maintenance practices. Regular inspection is recommended, particularly after driving in wet or sandy conditions. If you notice decreased performance, play in the wheels, or grinding sounds, it's time to replace the bearings. Many competitive racers replace bearings regularly as part of their maintenance schedule.
- Do these bearings require special tools for installation? — No, these bearings are designed for fast and easy installation using standard RC tools. They fit directly into bearing housings without modification, though you may use a bearing press tool or suitable installation tool to ensure proper seating.
- What makes 2RS bearings better than sealed bearings? — The 2RS (two rubber shields) design offers excellent protection against dust and water ingress whilst maintaining lower friction compared to some sealed bearing alternatives. The rubber shields flex slightly to deflect contaminants without creating significant drag, making them ideal for high-speed RC applications where smooth operation is critical.
- Will these bearings fit my ARRMA RC model? — These bearings are specifically designed for ARRMA vehicles and are compatible with numerous models including the Gorgon Grom, Granite Grom Mega 380, Mini Kraton 3S, Mojave Grom 223S BLX, Quake Grom, and Typhon Grom series. Check your vehicle's manual or contact us to confirm compatibility with your specific model.
- How do I maintain these bearings for maximum lifespan? — Keep your RC bearings clean by occasionally rinsing them with water after dirty driving sessions, ensure they spin freely without grinding or noise, and consider light lubrication with RC bearing oil if they become stiff. The rubber shields help prevent contamination, but regular cleaning extends bearing life significantly.
