The miniature dental ball bearing is one of the signature items in
the dental repair buissiness. Miniature dental ball bearings, like
all ball bearings, are designed to handle loads and reduce friction
so that those loads are moved easily through the application. Loads
handled by ball bearings can be radial, bearing loads perpendicular
to axle, or bearing loads in an axial direction.
A Choise of Angular Contact and Radial Configurations
Angular Contact Dental Bearings feature symmetrical cages. These enhance performance and extend
bearing life as each ball is fully supported and comptetely
surrounded by the cage. Angular contact bearings must be axially
preloaded with a spring or 0-rings to assure contact with the full
Radial Dental Bearings are less expensive and easier to work with than angular contact
bearings. They have full shoulders on both the inner and outer
raceways so they won’t disassemble during handling and instatlation
in the handpiece.
Dental ball bearings can have flanges or no flanges, shielded or
open. Many users prefer shielded ball bearings to protect against
contamination, but this may not be a particular concern in your
application. Stainless steel miniature ball bearings are perfect
for medical and dental equipment, they must be very small but also
very precise and durable, as well as corrosion-resistant. Stainless
steel ball bearings provide great corrosion resistance.
Both high-speed dental bearings and low-speed dental bearings provide manufacturers and dentists with a new standard in
handpiece performance — higher or optimal speeds, smoother
operation, longer life and reduced maintenance.
High precision miniature ball bearings that we deliver are produced
to the highest Quality Assurance standards, noise and vibration
tested to ensure smoother bearing operation, longer life, and
higher speeds. Dental bearings are available with few different
ball cage materials to meet the complete range of high-speed
Cage Materials to Match Application Needs
Cage wear and fracture are the leading causes of bearing failure.
For that reason it is critical that wear and autoclave resistance,
as well as price, be considered in choosing cage materials for a
particular operating environment. Phenolic is a good choice for
operating environments with minimal heat or chemical sterilization.
It will maintain low friction characteristics even in the absence
of proper lubrication. Torlon (Polyamide-imide) provides very good
autoclave resistance when proper maintenance protocols are
followed. Minapar cages offer a proven combination of wear and
autoclave resistance at competitive prices.
Minasure® LTL LifeTimeLube bearings are the first high-speed, self-lubricating dental bearings to
combine superior wear resistance with exceptional autoclave
resistance. These new premium bearings raise handpiece standards:
smoother operation, longer life and maintenance-free performance.
Unlike radial bearings, Minasure LTL bearings feature symmetrical
cages. Angular contact design enhances performance and extends
bearing life because — unlike radial designs — each ball is fully
supported and completely surrounded by the cage.
Low-speed Dental Bearings
Miniature ball bearings have become essential components in the
rotating elements of dental instruments. Dental ball bearings
performs as a critical part of dental handpiece. Dental handpiece
is required to hold high level of speed rotation and the lowest
vibration to minimize the stress of patients
