Product overview 2pcs speed handpiece stainless steel ceramic bearings designed as direct replacements for dental speed handpieces that require 3.175 x 6.35 x 2.380 mm bearings. Precision components made to restore smooth rotation and reduce vibration in rotary handpieces. Key benefits Precise fit and compatibility: Inner diameter 3.175 mm, outer diameter 6.35 mm, width 2.380 mm. Intended to bearings with these exact dimensions for many speed dental handpieces. Durable materials: Stainless steel raceways combined with ceramic rolling elements for improved wear resistance and longer service life compared to allmetal bearings. Low friction and smooth operation: Ceramic balls reduce friction at RPM, delivering more consistent rotation, lower vibration, and quieter performance. Corrosion resistance: Stainless steel construction helps resist corrosion in a humid clinical environment, maintaining reliable operation over time. Easy replacement: Supplied as a pair for routine maintenance or of handpieces that use two identical bearings. Performance highlights Designed for speed applications where low friction and stability are critical. Ceramic rolling elements help maintain precision at elevated rotational speeds. Compact dimensions for tightfit installations in turbine and handpiece assemblies. Typical applications Routine maintenance and overhaul of speed dental handpieces to restore smooth rotation and reduce operational noise. shops and service technicians replacing worn bearings during handpiece refurbishment. Dental training facilities and laboratories maintaining multiple handpieces used in instruction and practice. What you get Two precision bearings sized 3.175 x 6.35 x 2.380 mm, stainless steel races with ceramic rolling elements, packaged for convenient replacement. Installation and compatibility notes Confirm the existing bearing dimensions match 3.175 x 6.35 x 2.380 mm before . Installation may require proper tools and technique to avoid damage to the bearing or handpiece housing. Professional servicing is recommended if you are not experienced with handpiece . Compatible with speed dental handpieces that accept these bearing dimensions. Choose these bearings when you need a precise, durable replacement that helps restore smooth, lowvibration performance in speed dental handpieces.
