NTN spherical roller bearings have two rows of rollers and a spherical outer raceway that accommodates misalignment within the bearing’s design conditions. This geometry differs from self-aligning ball bearings. It should not be treated as a general remedy for a bent shaft, damaged housing or an installation whose position has not been checked.

This line includes 22208EMD1, 22209EMD1, 22208EMKD1 and 22209EMKD1. Because the codes are similar, retaining every letter is particularly important. A shared numeric series does not make two variants equivalent.
Copy the ring marking and compare it with the packaging or maintenance record. If they disagree, submit both readings rather than correcting one by intuition. Specific meanings of designation endings require confirmed documentation.
In mining equipment, mills and vibrating screens, the bearing forms part of a support whose working conditions should be described. State vibration exposure, shaft arrangement and lubrication method. These details provide context without automatically assigning a reference to a machine or establishing load and speed limits.
Record how the inner ring is mounted and identify accompanying retention components. Keep separate part references visible in the exploded drawing. A photograph of a closed housing may not reveal the internal arrangement that needs replacement.
Request a quote from MR with the NTN designation, quantity, equipment and position. Add photographs of the marking, mounting and identified retention parts. For a recurring failure, describe observations and known conditions without attributing the cause to misalignment before it has been investigated. Replacement identification and diagnosis need different evidence.
No. This family uses rollers and has a different construction; similar names do not establish interchangeability.
Keep them all. Variants sharing the numeric block need their complete designations.
No. Shaft condition, housing condition and mounting details still require separate evaluation.

The NTN spherical roller bearings with EMD1 suffix form a type with many series and sizes, such as 22208EMD1, 23148EMD1 or 24064EMD1. They all share the design of two rows of rollers with a spherical raceway in the outer ring, but the dimensions change with each number. That is why, to replace one, the full part number must be given.
The NTN spherical roller bearing is a component designed to withstand high radial loads and axial loads in both directions, with self-aligning capability. Its design with two rows of spherical rollers and a spherical raceway in the outer ring allows it to compensate for angular misalignment between shaft and housing, even under shaft deflection conditions. It is used in applications where alignment precision cannot be guaranteed, such as heavy machinery, conveyors and mining equipment. MR Accesorios Industriales sells this line.

The NTN B series spherical roller bearing is a component designed to withstand high radial loads and axial loads in both directions, with the ability to adapt to angular misalignment between shaft and housing. Its double-row roller and spherical raceway design allows stable operation even under misaligned mounting conditions. It is used in industrial applications where robustness and durability are critical, such as heavy machinery, mining equipment, steelmaking and power transmission. MR Accesorios Industriales is an official distributor of NTN.
