RPM Mega Bearing Blaster Hand-Operated Bearing Cleaning Tool RPM70420

Overview

The RPM Mega Bearing Blaster (RPM70420) is an essential maintenance tool for any serious RC enthusiast in the UK who runs larger-scale vehicles or uses oversized bearings. This innovative hand-operated bearing cleaning device takes up where the original Bearing Blaster leaves off, offering support for bearing sizes up to 1.25 inches (32mm) in diameter. Whether you're an RC car UK hobbyist running 1/5th scale models, a roller skater, skateboarder, or anyone using the immensely popular 608 bearing standard, the RPM Mega Bearing Blaster provides the best solution for keeping your bearings in peak condition.

Unlike the predominance of bearing cleaning devices and solutions currently on the market, the RPM Mega Bearing Blaster uses powerful pressure-based technology to blast debris from dirty bearings with instantaneous results. The results achieved by this compact tool are anything but small—bearings will be spotlessly clean in just seconds. The RPM Mega Bearing Blaster is still one of the smallest tools available in your RC toolbox, yet it delivers professional-grade cleaning performance that will keep your RC equipment running smoothly and efficiently.

This pressure-blasting approach is fundamentally different from traditional soaking methods or inefficient brushing techniques. When you own a quality RC model, whether it's a ready to run RC vehicle or a custom built competition car, bearing maintenance becomes critical. The RPM Mega Bearing Blaster ensures that internal friction is minimised and bearing life is maximised, giving you better performance and more reliable operation during those crucial race days or weekend bashing sessions.

Key Features

• Pressure-Based Debris Removal — Unlike traditional bearing cleaning methods that rely on soaking or manual brushing, the RPM Mega Bearing Blaster uses high-pressure blasting to forcefully remove dirt, dust and debris from bearings. This instantaneous cleaning action means your bearings are restored to like-new condition in just seconds rather than hours of labour-intensive cleaning.
• Extended Bearing Size Range — With a maximum outside diameter of 1.25 inches (32mm) and minimum inside diameter of 3/16 inch (5mm), this tool accommodates significantly larger bearings than the original model. This makes it perfect for 1/5th scale RC owners, skaters, skateboarders and anyone working with the popular 608 bearing format commonly used in the hobby.
• Safe, Contained Environment — The RPM Mega Bearing Blaster isolates the bearing in a fully contained environment, making it the safest way to forcefully blast debris from your bearings. This design prevents back-splash of cleaners and lubricants from hitting your hands and face, protecting you from harmful chemical exposure whilst you work.
• Dual-Purpose Tool — The same tool you use to clean your bearings can also be used to lubricate them with ease. Simply switch your spray from a cleaner to a lightweight lubricant, give it a blast and you're finished. This dual functionality makes bearing maintenance genuinely quick and effortless.
• Hand-Operated Design — This two-piece, hand-operated tool gives you complete control over the cleaning process. There are no complex mechanisms or electronics to worry about—just simple, reliable operation using hand pressure to hold bearings securely in place whilst you blast them clean.
• Compact Footprint — Despite its impressive cleaning capability, the RPM Mega Bearing Blaster remains one of the smallest tools available, making it the most efficient addition to your RC toolbox. It takes up minimal shelf space yet delivers maximum cleaning results when you need them.
• Simple, Foolproof Operation — Operation couldn't be easier. Simply remove the top, place the dirty bearing (with shields removed) on the centre cone of the base and replace the top. Insert the spray tube from your favourite can of cleaner into the top opening, hold it down and blast away until bearings are clean.

Technical Performance

The RPM Mega Bearing Blaster represents a significant engineering advancement in bearing maintenance technology. Unlike traditional bearing cleaning methods that can damage delicate bearing components or leave residual debris, this pressure-based system delivers controlled, effective cleaning that restores bearings to factory condition. The tool's open, flow-through design eliminates back-pressure entirely, ensuring your cleaning agent passes directly through the bearings for maximum debris removal without accumulating harmful residual pressure. The centre cone design on the base holds bearings securely and centred during the cleaning process, ensuring even distribution of cleaning pressure across the entire bearing surface. The two-piece construction is engineered for durability and repeated use, meaning this tool will serve your RC hobby for years to come. Construction quality is typical of RPM's reputation for producing professional-grade maintenance tools that stand up to regular workshop use. The compact dimensions of just 1-1/8 inches tall by 1-3/4 inches in diameter belie the engineering sophistication required to contain high-pressure cleaning spray safely whilst delivering effective results. Whether you're maintaining brushless RC car bearings, preparing vehicles for UK RC racing championships, or simply keeping your ready to run RC models in optimal condition, this tool is an investment that will pay dividends through improved performance and extended bearing life.

Frequently Asked Questions

• What size bearings can the RPM Mega Bearing Blaster clean? — The RPM Mega Bearing Blaster works on bearings with a minimum inside diameter of 3/16 inch (5mm) and a maximum outside diameter of 1.25 inches (32mm). This makes it suitable for 1/5th scale RC models, standard 608 roller skate bearings, and most larger-format RC vehicle applications. If you need to clean smaller bearings, RPM offers the original Bearing Blaster which handles bearings from 1/8 inch to 3/4 inch outer diameter.
• How quickly does the RPM Mega Bearing Blaster clean bearings? — Bearings will be clean in just seconds when using the RPM Mega Bearing Blaster. This pressure-based approach is far more efficient than traditional soaking methods which can take hours, making it perfect for race day maintenance or quick bearing refreshes between driving sessions.
• Can I use the Mega Bearing Blaster to lubricate as well as clean? — Yes, absolutely. The RPM Mega Bearing Blaster is a dual-purpose tool that works equally well for cleaning and lubrication. After cleaning your bearings with your preferred cleaner, simply swap the spray can for a lightweight bearing lubricant, place the cleaned bearing back into the tool and give it a blast. The high-pressure spray ensures even lubricant distribution throughout the bearing for optimal performance.
• Is the Mega Bearing Blaster safer than other bearing cleaning methods? — Yes, the RPM Mega Bearing Blaster is the safest way to forcefully blast debris from bearings. The contained environment design prevents back-splash of cleaners and lubricants from hitting your hands and face, eliminating exposure to potentially harmful chemical spray that can occur with less sophisticated cleaning methods or open-spray techniques.
• What is the difference between the RPM Bearing Blaster and the Mega Bearing Blaster? — The key difference is bearing size compatibility. The original RPM Bearing Blaster handles bearings from 1/8 inch (3mm) inside diameter to 3/4 inch (19mm) outside diameter, making it suitable for most standard RC car applications. The RPM Mega Bearing Blaster extends this range significantly, supporting bearings with a minimum inside diameter of 3/16 inch (5mm) and maximum outside diameter of 1.25 inches (32mm), making it ideal for 1/5th scale RC owners and those using larger bearing formats like the 608.
• How does the pressure-based cleaning system work compared to traditional methods? — Unlike traditional soaking, chemical baths or manual brushing which can be time-consuming and potentially damage delicate bearing components, the RPM Mega Bearing Blaster's pressure-based system forcefully blasts debris directly out of the bearing in seconds. The open, flow-through design ensures no back-pressure accumulates, allowing the cleaning agent to pass completely through the bearing for maximum debris removal. This approach delivers instantaneous, professional-grade results.
• Is bearing maintenance really necessary for RC hobbyists in the UK? — Absolutely. Clean, well-maintained bearings are essential for optimal RC vehicle performance. Dirty bearings create internal friction that increases power consumption, generates heat and reduces overall efficiency. Regular bearing cleaning using the RPM Mega Bearing Blaster will significantly extend bearing life, improve vehicle speed and handling, and ensure your RC car runs smoothly whether you're enjoying casual weekend bashing or competitive racing.
• Can I use any spray cleaner with the RPM Mega Bearing Blaster? — The tool works with your favourite can of spray cleaner, though the specific type isn't included with your purchase. Popular RC bearing cleaners include purpose-formulated products designed to dissolve grease and remove debris without damaging bearing components. The same principle applies when using it for lubrication—switch to a lightweight bearing lubricant for the maintenance cycle.
