Frequently Asked Questions

Can you supply bearings that require no grease or other lubricant?

We sure can! Almost all of our plastic bearings are oil-free and grease-free, requiring no lubrication. In addition, they can also be used in conditions with oil, grease, water, or any other liquid. A little lubricant can help, but is completely unnecessary.

Do you have any bearings made of a highly corrosion-resistant material?

You know, plastic does NOT rust, so a resounding Yes!.
If you inform us of the specific environment where the bearings will be used, then we can most likely supply what you need.

Do you offer Non-magnetic bearings?
