Timken High Performance Bearing Solutions
To better enhance equipment performance and reliability, Timken has integrated a range of unique high-performance bearing solutions that include P900 TM bearings, DuraSpexx TM bearings, anti-contamination bearings, engineered surface-treated bearings and resistance Corrosion bearing (see Figure 6). Each bearing is designed for a specific set of damage patterns. The service life of these high-performance bearings is between one and six times higher than that of ordinary bearings in different applications.
Timken P900 TM bearings and DuraSpexx TM bearings excel in load carrying capacity, efficiency and durability and are regarded by the industry as a benchmark. After the use of super-pure steel, the surfaces of the rollers, inner ring and outer ring of these bearings are specially processed to reduce the damage pattern associated with the surface (see Figure 5). In addition, the advanced geometry of the bearing is almost The boundary stress concentration caused by excessive load or eccentricity can be completely eliminated (see Figure 3). In certain conditions, the relative life of these bearings Timken ® bearings four times higher than the standard.
