LMK30UU Square Flange Linear Ball Bearing – 1 Pc

The LMK30UU is a square-flange type linear ball bearing designed for smooth linear motion along a 30 mm diameter shaft. The square flange allows the bearing body to be mounted securely on a flat surface or machine bracket, giving enhanced alignment and stability compared to plain cylindrical bearings.

Inside the bearing shell are hardened steel balls that circulate within ball tracks, reducing friction and enabling accurate, low-resistance sliding movement. This helps provide reliable performance in linear guide systems, especially where the shaft may travel long distances or the load is moderate.

Because the model suffix “UU” indicates sealed on both sides, the LMK30UU offers added protection against dust and contaminants and helps retain lubrication — making it suitable for industrial machine builds, automation setups, and CNC or 3D-printer axes using a 30 mm guide shaft.
