Deep Groove Ball Bearings SKF 6006 -Z/C3

The SKF 6006-Z/C3 deep groove ball bearing, measuring 30x55x13 mm, with a single-sided sheet metal cover and C3 clearance, offers a precise solution for demanding rotational movements.

This single-row deep groove ball bearing 6006 -Z/C3 from SKF is designed for predominantly radial loads whilst also accommodating axial forces in both directions. Manufactured from standard 100Cr6 rolling-element bearing steel in the Explorer design, the bearing features a sheet steel cage. Thanks to the increased radial clearance (C3) and manufacturing accuracy to tolerance class P6, the unit is suitable for applications involving thermal expansion or specific speed requirements.

Under what operating conditions is the 6006-Z/C3 deep groove ball bearing required?

This version is primarily used in bearing arrangements where thermal influences or tight fits occur. As the rolling bearing is designed for operating temperatures ranging from –20 to +150 degrees, the operating clearance remains stable even when the bearing heats up during operation. The single-sided Z-cover shield protects the interior from coarse dirt particles, whilst the open side allows lubricant to be supplied via the housing.

What are the functions of C3 bearing clearance and the Z-cover plate?

The C3 designation indicates a larger radial internal clearance compared with the standard version. This reserve compensates for fit allowances during press-fitting onto the shaft, as well as temperature differences between the inner and outer rings. Unlike abiding seals, the single-sided sheet metal cover does not generate any additional friction, which reduces heat build-up during operation. By design, the open side is oriented towards the lubrication side.
