FAQ

What does the 'EAE4' suffix signify on this NSK bearing?

The 'EAE4' suffix indicates specific internal design features. It designates a high-capacity design with a one-piece, high-strength pressed steel cage, making it suitable for high-load and general-purpose applications. Always verify the latest NSK catalog for the most accurate suffix definitions.

This bearing is typically shipped with a preservative rust-inhibiting coating, not a full operational lubricant. Before installation, it should be cleaned and then lubricated with a high-quality grease or oil appropriate for the application's speed, load, and temperature. For general machinery, an ISO VG 150 mineral oil or a lithium-based NLGI 2 grease is a common starting point.

Yes, a key feature of spherical roller bearings like the 21314EAE4 is their ability to accommodate misalignment. It can typically handle static misalignment of up to 2 degrees between the inner and outer rings without affecting its performance, making it ideal for applications where shaft deflection or mounting inaccuracies are expected.
