Single-row deep groove ball bearings with seals or shields on one or both sides are particularly versatile, offering low friction and optimized performance for low noise, low vibration, and high rotational speeds. They can accommodate both radial and axial loads in both directions, making them suitable for a wide range of applications. These bearings are easy to mount and require less maintenance than many other types. The integral sealing system significantly prolongs bearing service life by keeping lubricant within the bearing and keeping out dust. - Specification: Item R3-ZZ; Bore Diameter 0.19 in; Outside Diameter 0.50 in; Width, Total 0.20 in; Width, Inner Ring 0.20 in; Width, Outer Ring 0.20 in; Basic Dynamic Load Rating (Cr) 293 lbs; Basic Static Load Rating (C₀r) 110 lbs; Limiting Speed 43,000 r/min; Rolling Element Ball; Number of Rows 1; Locating Feature (Outer Ring) None; Bore Type Cylindrical; Cage Material Sheet metal; Radial Internal Clearance CN; Tolerance Class P6; Bearing Material GCr15; Sealing Shield on both sides; Sealing Type Non-contact; Lubrication Grease; Relubrication Feature Without; Product Weight 0.0023 kg.
