Feature:1. Reliable Work: Able to work in conjunction with cylindrical shaft with small operating load and frictional resistance.2. Ellipse Flange: The ellipse flange base has good bearing capacity, which promises good working stability and accuracy.3. Ball Bearings: Since the bearing ball is in point contact with the shaft, the whole operation has high work efficiency.4. Practical Use: Widely used in digital a variety of equipment as well as various guide rod, column, etc., very useful.5. Good Material: Adopting high quality bearing steel material, not easy to deform and very durable for long term using.Specification:Item Type: Linear Motion BearingModel: LMH25UUInner Diameter: Approx. 25mm / 0.98inDiameter: Approx. 40mm / 1.57inFlange Length: Approx. 60mm / 2.36inMaterial: Bearing Steel.Package List:2 x Linear Motion Bearing
