Deep Groove Ball Bearings FAG 61814

FAG 61814 deep-groove ball bearing: A single-row bearing with a 70 mm bore and an outer diameter of 90 mm, designed for compact, radial mounting in confined spaces.

The 61814 deep groove ball bearing is a single-row rolling bearing with a particularly narrow cross-section and a comparatively large shaft diameter of 70 mm. With a width of just 10 mm, this design primarily absorbs radial forces and also supports axial loads in both directions. Thanks to the flangeless cylindrical outer ring, the bearing can be fitted directly into smooth housing bores.

What installation spaces are required for the narrow deep-groove ball bearing 61814?

Design engineers opt for this design when, despite a large shaft diameter, only limited radial installation space is available within the housing. Typical applications include mechanical assemblies, fixtures and gearboxes with centralised oil lubrication. As the bearing is of an open design, the lubricant reaches the rolling elements and raceways unhindered. This is advantageous for applications where the surrounding environment is already protected against contamination by the enclosing housing.

What are the key considerations for the open design of the 61814?

As this rolling bearing is not fitted with sealing washers as standard, the bearing housing requires careful sealing in the housing cover or on the shaft. The integrated sheet steel cage guides the rolling elements with low friction. With its standard radial clearance and standard tolerance class P0 (ABEC 1), this model is suitable for typical industrial fit conditions. Before commissioning, ensure you select a lubricant suitable for the operating temperature range of -30 to +120 degrees.
