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 retaining lubricant within the bearing and preventing contaminants from entering. - Specification: Item R8-ZZ, Bearing Type R, Bore Diameter 12.7 mm, Outside Diameter 28.575 mm, Width 7.938 mm, Width Inner Ring 7.938 mm, Width Outer Ring 7.938 mm, Dynamic Load Rating Cr 4420 N, Static Load Rating Cor 2360 N, Limiting Speed 30000 r/min, Clearance Normal, Tolerance Inner Ring 0 to -7 μm, Tolerance Outer Ring 0 to -8 μm, Tolerance Classes P5, Cage Metal, Closures Shield on both sides, Lubrication Type Grease Chevron, Lubrication Temperature -30°C to +180°C, Rolling Element Indicator Ball, Material Gcr15, Product Weight 21 GR.
