The KaVo Mastermatic M05 L (6000M) and M25 L (7000M) are the industry standards for 1:5 high-speed red band contra-angles. At an output speed of 200,000 RPM, internal friction and heat are the enemies of precision. Our SR144/MR74 Series Ceramic Bearings are engineered specifically to restore the smooth, ‘Cool Touch’ performance of your Mastermatic attachments at a fraction of the OEM replacement cost.

The KaVo Mastermatic M05 L (6000M) and M25 L (7000M) are the industry standard for high-speed speed-increasing handpieces. However, the internal gear mechanism generates significant heat at 200,000 RPM.
Our Precision Ceramic Replacement Kits are specifically engineered to handle this thermal load. Featuring Grade 3 Silicon Nitride (Si3N4) balls and optimized cages, these bearings reduce friction and heat buildup, ensuring your ‘Red Band’ attachment runs cool and quiet.

Why Ceramic Bearings are Critical for 1:5 Attachments
Heat Dissipation Technology:
Steel bearings expand under the heat generated by 1:5 gears, leading to premature failure and a hot handpiece head. Our **Ceramic Balls have a lower coefficient of thermal expansion, maintaining their shape and clearance even during prolonged heavy-duty cutting.
High-Torque Stability:
The 6000M and 7000M are used for crown cutting and heavy prep work. Our bearings feature reinforced Torlon cages designed to withstand high radial loads without disintegrating, protecting your expensive internal gear shafts.
FAQ
Do these bearings fit the older KaVo GENTLEpower 25LPR?
Yes. The Mastermatic series is the successor to the GENTLEpower series. In most cases, the internal bearing specifications for the 1:5 head assembly are compatible. Please check our cross-reference chart or send us a photo to confirm.
How do I reduce heat in my KaVo 700?
Overheating is typically caused by worn bearings or lack of lubrication. Replacing old steel bearings with our Low-Friction Ceramic Kit significantly reduces heat generation. Also, ensure you are using the correct spray nozzle for internal irrigation.
Do you sell the intermediate shaft bearings?
Yes. A full rebuild often requires replacing not just the head bearings but also the bearings on the intermediate shafts. We offer complete overhaul kits. Please contact us for the full schematic part numbers
