With today’s high-speed handpieces operating at up to 500,000 rpm, precise and reliable dental bearing performance is critical. Timken has more than 50 years of experience with dental components, and a thorough understanding of dental applications. Timken dental handpiece bearings are designed with precision tolerances and robust components to meet the industry’s needs for high-speed performance.

Optimized Series

• Advanced polymer cage - High-strength design resists wear and autoclave environment, while improving stability and lubricant flow.
• Extended service life – On average, lasted 3 times longer than a common non-unrelubricated dental bearing in Timken laboratory handpiece testing.
• Value package - Combination of features designed for reliable operation and high customer value.
• Unequalled experience - Timken pioneered the development of high-speed dental bearings more than 50 years ago.
• 440C stainless steel - Provides hardness and corrosion resistance for bearing rings.
• Precision tolerances - Critical components meet ISO PA/ABEC 7 standards for better fit with reduced radial play, vibration and noise.
• Superfinished raceways - Smooth surface to reduce internal friction, vibration and noise for superior operating characteristics.
• High-quality balls - Grade 3 precision 440C stainless steel balls are standard
