FAQ

What is the difference between IKO NA 6914 and RNA 6914?

The NA 6914 is a complete needle roller bearing assembly that includes both the outer ring with rollers (designated as RNA 6914) and a separate inner ring (LRT708054). The RNA 6914 is just the outer ring and roller assembly, intended for applications where the shaft itself can be hardened and ground to serve as the inner raceway.

What are the recommended lubrication and mounting procedures for this bearing?

For the NA 6914, it is crucial to use a high-quality grease or oil suitable for needle roller bearings, depending on the operational speed and temperature. Mounting should be done using a press or a bearing heater to ensure even pressure on the rings and prevent damage to the rollers or raceways. Always refer to IKO’s official maintenance guide for specific lubricant types and mounting tolerances.

Can this bearing accommodate axial loads?

The IKO NA 6914 is a radial needle roller bearing designed primarily to handle high radial loads in a compact space. It can accommodate minimal axial displacement of the shaft relative to the housing but is not designed to support significant axial (thrust) loads. For combined radial and axial loads, a different type of bearing, such as an angular contact or tapered roller bearing, should be considered.
