Deep Groove Ball Bearings FAG 6217 -2Z-C3

The FAG 6217 -2Z-C3 deep-groove ball bearing, with dimensions of 85 x 150 x 28 mm, cover plates on both sides and a C3 clearance, offers a reliable solution for industrial applications.

This single-row deep-groove ball bearing 6217 -2Z-C3 from FAG primarily absorbs radial forces, but also supports shafts under moderate axial loads in both directions. Manufactured from standard 100Cr6 rolling-element bearing steel and featuring an integrated sheet steel cage, the component covers a wide operating range. The manufacturing accuracy complies with tolerance class P0 or ABEC 1. It has no groove or flange on the outer ring.

What is the 6217 -2Z-C3 deep groove ball bearing suitable for?

Design engineers and maintenance technicians use this design primarily in rotating shaft assemblies subject to continuous operation and high speeds. The specified temperature range is from –30 to +120 degrees Celsius. The non-contact gap seals help to minimise the ingress of coarse dirt particles without generating additional frictional heat inside the bearing. This promotes smooth running with minimal rotational resistance.

When is the combination of 2Z cover plates and C3 bearing clearance appropriate?

The C3 designation indicates a slightly increased radial bearing clearance. It compensates for thermal expansion when the inner ring becomes warmer than the outer ring during operation, or when tight fits on the 85 mm shaft reduce the bearing clearance. In combination with the sheet metal end plates (-2Z) on both sides, the lubricant remains protected within the rolling chamber, whilst the system continues to rotate freely even when heated and counteracts stress.
