MAPLE ACE 687-ZZ Ball Bearing 7x14x5mm 687 ZZ Metal Shielded (PCs 4)

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 retaining lubricant within the bearing and preventing contaminants from entering. - Specification: Item 687-ZZ, Bearing Type 680, Bore Diameter 7.00 mm, Outside Diameter 14.00 mm, Width 5.00 mm, Dynamic Load Rating Cr 780 N, Static Load Rating Cor 260 N, Limiting Speed 50000 r/min, Clearance Normal, Tolerance Inner Ring 0 to -7 μm, Tolerance Outer Ring 0 to -7 μm, Tolerance Classes P5, Noise and Vibration Z3V3, Closures Shield on both sides, Lubrication Type Grease Chevron, Lubrication Temperature -40°C to +150°C, Rolling Element Indicator Ball, Material Gcr15, Product Weight 0.003 KG.
