Product type: 6900 series thin-section deep groove ball bearings
Bearing structure: Thin-section deep groove ball bearing with compact rings and a relatively small outside diameter. Open, ZZ metal-shielded and 2RS rubber-sealed versions are available. Material options include high carbon steel, bearing steel, stainless steel and customized specifications.
The 6900 series provides smooth rotation in compact equipment with limited radial installation space. Its thin cross-section and relatively small outside diameter help reduce the size and weight of the surrounding mechanical assembly.
Compared with the 6800 series of the same bore size, the 6900 series normally has a larger cross-section and higher load capacity. Common models listed in the page description include 6900, 6901, 6902, 6903, 6904 and 6905. Open, ZZ and 2RS versions can be selected for different operating environments, and the bearing can be assembled with plastic, rubber or metal outer wheels.
Product Applications
A 6900 series thin-section deep groove ball bearing is suitable for compact mechanisms that need a balance between radial space and load support. Typical applications include:
Compact sliding door and window rollers: the bearing supports the rotating wheel inside a small roller housing.
Wardrobe and furniture guide wheels: the thin bearing can be integrated into compact carriage and guide-wheel assemblies.
Plastic-coated bearing rollers: the bearing can be combined with a plastic outer wheel for a coated roller assembly.
Small electric motors: the bearing supports smooth shaft rotation in compact motor designs.
Robotics and automation equipment: the bearing can be used in lightweight joints, guides and positioning mechanisms.
Measuring instruments and office equipment: the thin bearing supports space-limited rotating components.
Printing equipment: the bearing can be selected for compact guide and shaft assemblies.
Medical equipment and custom thin-section roller assemblies: the bearing can be matched to a specific shaft, housing and outer wheel design.
