Two open type linear bearing blocks designed for SBR50 50 mm linear guide rails, compatible with SBR50 series rails. This product is a 2 pieces per lot set, identified as SBR50UU and SME50UU, for open type linear motion on 50 mm rails. Key benefits Provides smooth, lowfriction linear motion along 50 mm guide rails to improve positioning accuracy and repeatability. Open type design facilitates installation in tight spaces and simplifies maintenance and lubrication access. Two bearing blocks per lot enable parallel or pairedaxis configurations, or use as spares for downtime reduction. Specifically matched to the SBR50 50 mm linear guide rail system, supporting standard assembly in compatible equipment.
