NEW NIPPON BEARING SMKC-30UU

The Nippon Bearing (NB) SMKC-30UU is a Center Mount Square Flange Type linear slide bush designed for precision linear motion applications. The SMKC series features a square flange with the mounting holes positioned at the center of the bearing length, allowing for mid-span mounting in machine designs where end-mounting is not practical. The UU suffix designates nitrile rubber seals on both sides to protect internal ball circuits from contamination and retain lubrication.
