(1) Target markets
Industrial machine field in general, including paper- and iron-making equipment; construction, agricultural, and mining equipment; reduction gears, etc.
(2) Market needs
Spherical roller bearings provide good alignment performance due to the spherical shaped raceway and rollers, and they have been adopted in a wide range of industrial machine fields because they are easy to work with and have a high load capacity compared to other bearings. With the rise in industrial-machine performance in recent years, it has become increasingly necessary to handle even higher axial loads* and high-speed rotation.
Our company is now introducing the "EXQ Series" of spherical roller bearings in order to satisfy high-load and higher-speed needs in a wide range of industrial machine fields.
(3) Characteristics
a. Greater axial load bearing capacity
Through optimization of the internal shape, axial load bearing capacity has been increased up to 25% compared to past products. This has enabled utilization in high-load applications where use of spherical roller bearings has been considered difficult in the past.
b. Increase in limiting speeds
Since roller rotation conditions have been stabilized and bearing heat generation reduced, we have achieved world-class limiting speeds that are approximately 10% higher than those of past products. This will contribute to greater production efficiency by enabling greater speeds and greater efficiency for industrial machines.
c. Handling of 200°C
Performing heat stabilization processing as a standard process has made possible use in high-heat (up to 200°C) environments.
d. High impact resistance
The definition of "EXQ-V Specifications" has greatly increased cage impact resistance to also support usage in severe environments such those of mining machines.
(4) Product Lineup
We have 109 models with bearing outside diameters from 52 mm to 280 mm.
*Axial load
The load placed parallel with the rotation axis of the bearing. Also called thrust load.
(Supplemental information)
In general industrial machines (large equipment, etc.), axis flexure is large and mounting errors can easily occur so frequent use is made of spherical roller bearings which can handle axial loads in addition to the load perpendicular to the rotation axis (radial load).
