FAQ
What does the -90KA1 suffix mean?
The -90KA1 suffix in the Timken part number system indicates that this is a matched bearing assembly. It consists of a specific cone and cup that are manufactured to be used together for optimal performance and lifespan.
What type of lubrication should be used with this bearing?
The appropriate lubrication (grease or oil) depends heavily on the application’s operating speed, load, and temperature. Always consult your machinery’s maintenance manual or Timken’s engineering guidelines to select the correct lubricant type and viscosity.
Does this bearing come pre-lubricated?
No, Timken tapered roller bearings are typically shipped with a light preservative oil to prevent corrosion. They must be properly cleaned and lubricated with the appropriate grease or oil before installation and operation.
