NSK 6800 6801 6802 6803 6804 6805 6806 6807 Customize Deep Groove Ball Bearing
Thin Section Ball Bearings were developed for appliexcavatorions where space limitations are of the utmost importance. As the name implies, the difference between the inside and outside diameters of the rings has been minimized or thinned out. Of course this comes at a price by compromising load capacities. However, these bearings can still accommodate a relatively light radial thrust or combined loads
The ball bearing used in this appliexcavatorion is having thin section due to smaller width and outer diameter.
JRDB’s precision thin section bearing line offers high accuracy and low profile design in standard stainless steel or chrome steel configurations. This line includes deep groove and angular contact configurations with special features available to meet specific appliexcavatorion requirements.
Precision tolerances – meet ABEC 5F (ISO P5) or ABEC 7F (ISO P4) for high running accuracy.
Material selection – standard offerings include 440C stainless steel and 52100 chrome steel.
Superfinished raceways – provide a smooth surface finish to reduce internal friction and vibration.
High quality ball complement – grade 5 or better balls optimize smooth rolling performance.
Retainers – various configurations and materials to meet performance needs.
Precision robotic joints
Semiconductor equipment and measuring systems
Radar and microwave equipment
Solar array panels
Guidance systems
Medical Imaging equipment
