Feature: 1. STANDARD SIZE: Linear ball bearings are used in conjunction with quenched linear drive shafts, with standard inner and outer diameters, stable in operation. 2. GOOD PERFORMANCE: The load ball and the hardened drive shaft are in point contact, with small allowable load, low friction resistance and high accuracy during motion. 3. BEARING STEEL: Made of bearing steel, with special heat treatment process, this linear ball bearing has high hardness, wear resistance and long service life. 4. FOR CNC SYSTEM: Oval flange design, these ball bearings are often used in CNC linear motion systems, for mechanical sliding parts, stable and reliable. 5. WIDE APPLICATION: Widely used in electronic equipment, coordinate measuring equipment, machine tool punches, printers and sports equipment, etc. Specification: Item Type: Linear Ball Bearing Model: LMH16UU Material: Bearing Steel Quantity: 2PCS Inner Diameter: Approx. 16mm / 0.6in Outer Diameter: Approx. 28mm / 1.1in Height: Approx. 37mm / 1.5in.
