Luoyang SBI Special Bearing Co.,ltd (SBI; Headquarters: Luoyang, Henan,China; President and CEO: Wangdi) announced that it has expanded the size of large spherical roller bearings for Industrial Machinery.

SBI has added 400 to 600mm size range bearings to its large spherical roller bearings. These bearings achieve twice the life of conventional bearings and offer 30% lower heat generation and dimensional stability under high temperatures (up to 200°C). The bearings also help improve productivity and reduce maintenance costs by improving the reliability of industrial machines.

Development Background

SBI is strengthening its position in the aftermarket by focusing on the MRO (maintenance, repair, and operation) business. The MRO business demands comprehensive product power that adds reliability and after-sales service with superior product performance.

In response to these demands,SBI has been leveraging its development, design and production technologies to expand the lineup and performance of its standard bearings. Since SBI first introduced the spherical roller bearings, it also added angular contact ball bearings ,slewing drive in 2010,all kinds of slewing bearing with diameters from 4mm to 6000mm, and deep groove ball bearings and small cylindrical roller bearings , as well as other special bearings, for a total of six types of bearings ranging to a maximum size of 400mm.

Due to increased demand,SBI has expanded the size range of spherical roller bearings to further strengthen its MRO business for a wide range of industrial machines.

New Product Features

SBI has independently researched the cause of damage that is specific to spherical roller bearings to develop technology that increases bearing life. In addition to this technology, SBI developed and applied low heat generation technology to produce the following features for these new bearings:

Long life: The new bearings suppress friction of the outer ring and rollers and reduce the slip of the inner ring and rollers to offer twice the life of conventional bearings.

Low heat generation: The cage and the guide ring design have been optimized to suppress tilting in the rollers creating 30% less heat generation of than that of conventional bearings.

Dimensional stability under high temperatures: Heat treatment has been applied for dimensional stability for temperatures up to 200℃.

New Product Benefits

SBI contributes to improving productivity and lowering maintenance costs for its customers by increasing the reliability of industrial machines.
