Produktbeschreibung

Miniature Bearing Types & Features
Miniature and instrument ball bearings can be divided into two basic types, deep groove and angular contact. The first (deep groove) can also be classified as "Open", "Shielded", or "Sealed" depending on the existence and type of seal or shield. Deep groove ball bearings have two inherent advantages
they can sustain some axial load in either direction as well as radial loads, and the two raceway cross-sections are simple circular arcs which can be very precisely finished so the bearings have low friction and very little noise or vibration. Several different cage designs are available with different characteristics and the choice depends upon the individual application.
Pic1: Showing contacts between the rolling elements with inner and outer raceways.
Pic2: Through stress life fatigue analysis, it shows that the high precision bearing has longer fatigue life and higher safety factor.
DIMENSIONS LIST
Purposes of Lubrication
The main purpose of lubrication is to reduce friction and wear inside bearings that may cause premature failure.
The effects of lubrication can be briefly explained as follows
(1) Reduction of friction and wear
Direct metallic contact between the bearing rings, rolling elements and cage is prevented by a lubricant film.
(2) Extension of fatigue life
The rolling fatigue life of bearings depends greatly upon the viscosity and film thickness between the rolling contact surfaces. Sufficient film thickness prolongs the fatigue life while film thickness shortens it.
(3) Dissipation of frictional heat and cooling
Circulating lubrication may be used to carry away frictional heat or heat transferred from outside the bearing.
(4) Others
Adequate lubrication also helps to prevent foreign matter from entering bearings and guards against corrosion and rust.
