Why do we recommend that customers purchase TIMKEN bearings as a set? This is based on the unique design principles, precision requirements, and optimal performance of TIMKEN bearings.


TIMKEN tapered roller bearings are designed to be "matched":

-The inner ring, outer ring, rollers, and retainer of TIMKEN tapered roller bearings are manufactured separately, and their tolerances are independently controlled.


-TIMKEN bearings select the most matching inner and outer rings from the final machined inner and outer rings, assemble them together, and undergo rigorous testing to create a perfect set.


-If customers purchase either outer or inner ring separately, even if they are identical models, there is no guarantee of matching. Randomly mixing and matching can lead to looseness within the bearing, making it incompatible and inoperable. Don't lose the big picture for the sake of a small gain.

So what's the biggest risk of purchasing TIMKEN bearings as a set?

That's right: uncontrolled clearance.

-Excessive clearance will increase the heat generated by the bearing during operation. High temperatures can render the lubricant ineffective, ultimately causing the bearing to burn out quickly, seize, and damage the equipment. This is a chain reaction.


- Excessive clearance can cause unstable bearing operation, generating noise and vibration, accelerating the separation of the rollers from the rollers, and significantly shortening the bearing life.


We recommend that customers purchase TIMKEN bearings in sets based on our technical background and professional advice that is responsible for our customers' equipment. 

Our goal and pursuit is to ensure that our customers receive a product that satisfies their needs!
