I would like to refill a product with a grease other than the one included at purchase. Is this a problem?
Mixing different greases may cause unforeseeable changes and prevent the grease from performing as expected.

If you want to replace a grease or have accidentally mixed greases, we recommend doing one of the following.

(1) Return the product to THK and have the inside of the product cleaned.
(2) Add new grease to flush out the old.
