High-Speed Performance
Precision-engineered 440 stainless steel ensures ultra-smooth rotation at high speeds, ideal for dental handpieces requiring minimal friction and heat generation.
Durable & Corrosion-Resistant
440-grade stainless steel construction offers superior hardness (HRC 58-60) and rust resistance, extending bearing life even in sterile dental environments.
Deep Groove Ball Design
Optimized raceway geometry distributes load evenly, reducing vibration for stable operation during delicate dental procedures.
Medical-Grade Precision
Tight tolerances (ABEC-1 or higher) guarantee consistent performance in high-torque applications like turbine-driven dental tools.
OEM Compatibility
Direct replacement for SR144/SR144TLZN/R144 bearings, compatible with major dental handpiece brands including Kavo and NSK.
Bulk Purchase Advantage
Wholesale pricing available for clinics/hospitals needing large quantities without compromising quality standards.
