2 Type EA Longer service life and higher rot while contributing to mo Ultage Series spherical rollers bearings are innovative to provide longer service life, higher rotational speed, and Longer Service Life Larger rollers provide the industry s highest load capacity. Extended maintenance intervals Lighter and more compact design Withstands operating temperatures up to C. Higher Rotational Speed The industry s highest allowable rotational speed Simple windowtype configuration employs a pressed steel cage. The back face of the cage provides a guide function that eliminates the guide ring. Improved EaseofUse Unique structure readily accepts lubricant. Easy application of grease ULTAGE (a name created from the combination of ultimate, signifying refinement, and stage, signifying NTN s intention that this series of products be employed in diverse applications) is the general name for NTN s new generation of bearings that are noted for their industryleading performance.

5 The ULTAGE Advantage Type EA 1 The industry s highest load capacity These bearings have a significantly increased roller diameter and incorporate the maximum number of rollers, thus achieving both a high load capacity and a longer service life. Maintenance intervals can also be extended. Figure 1 1 Basic dynamic : up to % greater than the NTN conventional design Basic static : up to % greater than the NTN conventional design Service life: up to five times longer than the NTN conventional design NTN EA conventional design The industry s highest allowable speed The new pressed steel cage results in allowable bearing speeds up to % greater than NTN s conventional design. Four cage pocket tabs stabilize the roller position Figure Pressed steel cage provided as standard. The windowtype pressed steel cage provides higher rigidity. Each roller pocket is provided with four tabs. 1 The guide system employs a backtoback cage system. Four tabs in each cage pocket stabilize the roller position. The innovative cage pocket shape ensures a stable supply of lubricating oil or grease into the bearing. A special surface treatment enhances wear resistance. Figure Compact, lightweight design The increased load capacity contributes to a lighter and more compact design.

11 Spherical roller bearings carry a radial load, a bidirectional axial load, or a combination of both. They are suitable for applications involving vibration and impact loads. However, if a spherical roller bearing is used under an excessive axial load, the load on the rollers of the row not receiving the axial load will be reduced and the rollers in this row move with a sliding motion, possibly leading to lubrication failure and other problems. In case that the ratio of axial load to radial load exceeds Constant which is in the dimension table please contact NTN Engineering. :Axial load. :Radial load. :Constant(See dimension table) Higher bearing speeds result in higher bearing temperatures caused by friction. When the bearing temperature exceeds a specific limit, lubricant performance deteriorates significantly, leading to abnormally high temperatures and bearing seizure. The limiting factors that affect allowable bearing speed include the following: (1) Bearing type () Bearing size () Lubrication system (grease, circulating lubrication, oil bath, etc.) () Bearing internal clearance (internal clearance of running bearing) () Bearing load () Dimensional accuracy with shaft, housing, etc. The allowable speeds indicated in the bearing dimension table are for reference only and apply only when bearings are lubricated and heat is efficiently drawn away from the bearing. The allowable speeds in this catalog are categorized as follows: Oillubricated bearings The bearing speed at which the outer ring temperature reaches C when the bearing is allowed to run at % basic static while lubricated with oil (viscosity VG) which is assimilated to room temperature and fed at a rate of 1 liter/min (circulating lubrication) Greaselubricated bearings The bearing speed at which the outer ring temperature reaches C when the bearing, which has undergone runningin operation, is allowed to run at % basic static with the bearing s internal free volume to % prefilled with lithium grease (consistency: NLGI) With either lubrication system, the bearing temperature rise profile varies with the operating conditions (operating load, running speed pattern, lubricating conditions, etc.) in which the bearing is used. Therefore, select the optimal bearing by allowing sufficient margin for the allowable speed for that particular bearing as indicated in the catalog. Contact NTN Engineering for technical assistance if the bearing speed in the intended application exceeds % of the allowable speed indicated in the bearing dimension table, or if the intended bearing is to be used under severe operating conditions involving vibration and impact.
