寸法: Standard 608 size (8mm Bore, 22mm Outer Diameter, 7mm Width).
Load Ratings: 動定格荷重 (Cr): 12 kN | 静定格荷重 (Cor): 6.65 kN.
Speed: Engineered for high RPMs, allowing for incredible acceleration and sustained coasting speed that steel bearings cannot match.
Weight: Up to 30% lighter than all-steel bearings, reducing rotational mass for quicker wheel response and a more agile board feel.
耐久性: The combination of materials makes these bearings virtually impervious to rust, corrosion, and wear from dirt and moisture. They perform consistently in wet or dry conditions.
Maintenance: Requires less frequent cleaning and lubrication than standard bearings. The included high-speed lubricant is optimized for the ceramic-steel interface.
Our premium dental handpiece bearings are engineered to meet the extreme demands of modern dentistry. Designed forhigh-speedoperation, exceptional quietness, and extended service life.
