Analysis of TIMKEN bearing engineering surface treatment and coating technology

Timken invested nearly 80 million U.S. dollars to develop special surface treatment processes for timken bearings. Why did Timken spend such financial and human resources to develop this technology? The original technology can increase the power intensity of bearings, reduce wear, improve marginal lubrication performance, have better anti-abrasive ability, reduce warranty costs, and increase the durability of the system.

Although the bearing life and performance are largely determined by the part geometry and metallurgical factors. But it can also improve its performance by changing its surface condition. For example, when the gears are engaged, the shaft rotates in the bearing housing and the rolling elements of the bearing run on the raceways. Through surface finishing and special coating, friction can be reduced and the life of the equipment can be extended.

Timken bearings This innovative special surface treatment process has two major technologies: special surface treatment and anti-abrasive solutions. Special surface treatments are achieved by modification of the surface of the part (changing the finishing of the surface) and special coatings. Compared to traditional grinding and honing methods, these methods can make the surface roughness lower. Of course, in most cases, a certain degree of roughness is actually needed because it also needs to provide the necessary space for lubrication.

Despite this, special surface treatments are also limited. They are only suitable for parts that have a certain range of dimensions and have a suitable geometry. Timken's special surface treatment technology can increase the power density of parts, reduce wear and reduce frictional losses, enable higher bearing performance, lifetime and system durability, and reduce warranty costs.

Another major new technology anti-abrasive grain bearing from Timken shines in a dusty and abrasive environment. It is designed for abrasive grain environments where bearing performance and productivity are affected. Timken anti-abrasive grain bearings are obtained through specialized heat treatment processes, material selection, and unique process control that optimizes strength, plasticity, and toughness.
