Vibrating Screen Spherical Roller Bearing

Product Description

Spherical Roller Bearings with High-strength Cage EMA Type

Industrial machineries are typically used under extremely severe operating conditions (eccentric rotation and impact load, for example). ULTAGE series spherical roller bearings with a high-strength cage EMA type are our new standard series bearings developed to satisfy the needs of such heavy-duty machineries for improvements in long life, vibration resistance, and low temperature rise characteristics.

Key Features 

• Load capacity of the worlds highest level
• Maximizing the size and the number of the rollers achieved high load capacity and long life.
• Extended maintenance intervals

Downsizing and light-weighting opportunities 

• Basic dynamic load rating: max. 20% up (vs. our conventional bearing)
• Long life: max. 2X (vs. our conventional bearing)

High strength cage 

• Modifying its shape and incorporating staggered pockets increased cage strength.
• Improved vibration resistance
• Outer-ring-guided cage more resistant to vibration and eccentric rotation
•  Special specification available for vibration screens
• Cage strength: max. 55% up (vs. our conventional bearing)

Low heat-generation 

• Optimizing internal bearing design including curvature reduced temperature rise.
• Permitted rotational speed of the worlds highest level
• Temperature rise: max. 10% down (vs. our conventional bearing)

Heat resistant up to 200 degree C

Being heat-treated by a special method, these bearings exhibit excellent dimensional stability at high temperatures, contributing to extended service life.
