High precision dental bearing SR144TLZ
Handpiece bearings are some of the most highly scrutinized in the bearing industry due to their high speeds when in use, and expected exposure to the constant heating and cooling of the autoclave cycle between uses. Tolerances (distances between rotating and stationary parts) are some of the very tightest in the industry.
Material:
Rings: AISI440C
Balls:Si3N4 Ceramic balls or stainless steel balls
Ceramic balls: (20% harder than conventional bearings with steel balls, 50% the weight of the steel equivalent,
frictional wear between the bearings and bearing retainers is significantly reduced, Noise is very low.)
