Camera Bearing Miniature Ball Bearing 618/3 Deep Groove Ball Bearing
Deep Groove ball bearings are the most popular of all the ball bearing types because they are available in a wide variety of seal,
shield and snap-ring arrangements.
The bearing ring grooves are circular arcs made slightly larger than the radius of the ball. The balls make point contact with the
raceways (elliptical contact when loaded). The inner ring shoulders are of equal height (as the outer ring shoulders).
Deep Groove ball bearings can sustain radial, axial, or composite loads and because of simple design, this bearing type can be
produced to provide both high-running accuracy and high-speed operation.
This series is used where space limitations are primary consideration and shafts are relativey large. Available with
open,shields,seals or snape tings reques.The main radial load ,but also can withstand a small amount of axial load.Suitable for
high speed and low noise ,low vibration.Radial clearance is selected in accordance to applications ranging from C2,C0, C3 ,C4
fits.lubricated with good grease, the sealed bearing can acquire better operational and life performance.
Deep groove ball bearing feature :
1.The most representative of the rolling bearings, widely used
2.Outer ring with a ring or flange bearing, that is easy to axial positioning, and easy to install the shell;
3.The maximum load bearing size is the same as the standard bearing, but the inner and outer rings have a trough, which increases
the number of balls and improves the rated load.
1. High temperature resistance, with high glass transition temperature and melting point (334℃), its load thermal deformation temperature is up to 316℃, continuous use temperature is 260℃;
2. Superior sliding characteristics, suitable for use with strict requirements for low friction coefficient and wear resistance;
3. Hydrolysis resistance, continuous use in high temperature and high pressure water can still maintain excellent characteristics;
4. Radiation resistance; 5. Fatigue resistance; 6. Corrosion resistance
7. Solubility resistance
8. Good wear resistance, anti-static electrical insulation performance
