Deep Groove Ball Bearings of the series C-638 (Hybrid)
- designed as hybrid deep groove ball bearing: rolling elements made of ceramic, inner and outer ring made of stainless steel
- cage material: plastic; the low weight and the elasticity of the plastic have a positive effect on the sliding and emergency running properties as well as the shock resistance; suitable for quiet running
- lighter than comparable deep groove ball bearings with steel balls as rolling elements; ceramic balls have a current-insulating effect; withstands higher speeds and has a high wear resistance
- wider than comparable deep groove ball bearings of the series 68
- thin section bearing with very thin, square cross section
- suitable for space-saving installation in radial and axial directions
- suitable for very high speeds compared to deep groove ball bearings with a larger cross section
- extra light series with compact dimensions and low weight
- suitable for radial loads and light axial loads in both directions
- offers high running accuracy, quiet running and very high speeds
- seal: contact lip seal on both sides made of rubber (2RS) for high sealing effect
- If you need this bearing in RS design with only one seal and one open side, you can simply remove one of the two seals: to the instructions
- good fixed bearing property, but can also be used as a floating bearing, each in both directions
- manufacturers of bearings, such as FAG, KOYO, NSK, SKF, SNR, OEM, etc. assign different suffixes for their characteristics, for better orientation take note of the comparison table of bearings (see further information)

Special feature of this series
Main dimensions according to DIN 625-1. Hybrid thin section bearings of this series are equipped with low-wear, current insulating ceramic balls withstanding extremely high speeds. They have considerably smaller dimensions than deep groove ball bearings of the 60, 62, 63 and 64 series with their thin, rectangular cross-section at the same inside diameter. Relatively high shaft- and axis diameters can thereby be installed at an also extremely confined installation space. They have the same outside diameter like thin section bearings of the 68 series, are nevertheless broader. They are extremely light and are suitable for comparatively very high speeds. They are available with rings made of stainless steel or rolling bearing steel.

Can be customized to meet your specific needs.
The hybrid deep groove ball bearing SS-C-63800-2RS-TN has excellent properties due to the ceramic rolling elements. It is the wider version of the 68 series. It is particularly suitable for achieving a good load capacity in extremely limited space conditions. Main dimensions according to DIN 625-1.
Other options: Metal shield (ZZ) or rubber seal (2RS) can be provided.
Deep Groove Ball Bearings are able to accommodate low to heavy radial loads and low to moderate thrust loads in either direction. They are available with metal shields (ZZ) or rubber seals (2RS). Several tolerance grades (Abec 1-9), internal clearance (C2 to C4) and cage designs are available to best suit the running precision and speed of the application.
- ZZ– Two Metal Shields
- 2RS– Two Rubber Seals
- NR– Snap Ring
- M– Brass Cage
- C0– Normal Internal Clearance
- C3– Greater than normal
