Construction Machinery

Construction machinery is typically deployed in remote mining sites, such as mountainous 

and desert regions, far removed from everyday human habitation. These machines operate 

continuously, 24 hours a day; a breakdown in any of them can have a significant impact on 

production at the mining site. Furthermore, the increasing size of modern machinery has 

made maintenance work particularly arduous. Consequently, in terms of bearing operating 

environments, there are numerous conditions that are extremely demanding for bearings, 

such as ‘heavy loads + impact loads’, ‘light loads + high-speed rotation’ and ‘heavy 

loads + low-speed rotation’. Therefore, the bearings sought by users are products that 

possess the robustness, durability and high reliability required to withstand these harsh 

operating conditions.

The frequent start-stops, polluted environments and continuous vibrations characteristic of 

construction machinery require products with superior performance to meet these challenges. 

To satisfy these user requirements, we supply a wide range of bearings and seals, whose 

enhanced features protect components from excessive wear. Furthermore, our expertise in 

lubrication helps to extend bearing service life and maintenance intervals.
