638-2RS ball bearing is typically used in applications that require high-speed operation and moderate radial and axial loads.
It can be found in various equipment and machinery such as electric motors, household appliances, automotive components,
and industrial machinery.
6300 series single row deep Groove Ball Bearings offer multiple options that serve a wide range of applications. The 'groove' is the depth of the raceway into which the balls fit, they typically consist of an Inner Ring, Outer Ring, Balls and Cage. Variants are available with Steel Shields, Rubber Seals (Contact/Non-Contact type), Snap-ring Grooves with Snap-rings, and a variety of Cage types. model from 634, 635, 636, 638, 63800, 6301, 6302, 6304, 6305, 6306, 6307, 6308.....
These Bearings are designed for radial, axial, and also composite load applications, purpose of deep groove precision ball bearings is to reduce rotational friction and support radial and axial loads.Deep Groove Ball Bearings offer:
·Uni or bi-directional load carrying capability
·Very high-speed rotation
·Very good running accuracy
·Low noise and low friction torque
