How to Select Your Size
Match the bearing's inner diameter to your guide rod shaft diameter. For example, if your rod shaft is 8mm, select the LMF8UU. If you require a size or model not listed, please contact us — we're happy to help source the right bearing for your build.
For technical guidance on bearing selection and linear motion systems, refer to the NIST Manufacturing Technology Resources.

Frequently Asked Questions
Q: What is the difference between LMF and LM series linear bearings?
A: The LMF series features a round flange on one end, making it easy to mount by bolting directly to a flat surface. The standard LM series (e.g. LM8UU) is a plain cylindrical bearing that is pressed or retained in a housing. For applications where direct surface mounting is needed, the LMF round flange design is the preferred choice.
Q: Are these LMF series bearings compatible with standard smooth rod shafts?
A: Yes. LMF series bearings are designed to work with standard hardened and ground smooth rod shafts of the corresponding diameter (e.g. LMF8UU fits an 8mm diameter rod). They are widely compatible with rod shafts used in 3D printers, CNC machines, and linear actuator systems.
Q: Can I order multiple sizes in one order?
A: Each listing covers a single piece of one size. The minimum order quantity (MOQ) is 1 piece. To order multiple sizes or larger quantities, simply add the desired size and quantity to your cart, or contact us for bulk pricing options.
Q: Do these bearings require lubrication?
A: For optimal performance and longevity, it is recommended to apply a light coat of machine oil or bearing grease to the guide rod before installation. Regular lubrication helps maintain smooth, consistent linear motion and extends the service life of the bearing.
