I would like to add the stock solution of GOLD to the bearing grease. Please let me know if there is a recommended addition rate.

We also sell grease type of LS bell hammer and LS bell hammer GOLD.
We hope that you can select the grease consistency (hardness) that matches the existing product and use it in the right place.
In addition, when adding the undiluted solution to existing grease, I think that adding 5 to 10% will be sufficient, but if possible, add about 15%.
