    LM25UU Metric Linear Ball Bearings with Rubber Seals

    $20.92
    LM25UU 25mm linear motion bearings are produced with a chrome steel outer cylinder, polyamide retainer, bearing balls and two side seals to prevent invading dirt and moisture. The bearing ball is in point contact with the shaft so that the friction resistance is small and the bearing balls are suitable for low-load and high speed movement.

    Tips: Ten Advantages of ATO Linear Ball Bearings

    1. High precision
      The LM linear bearing has a hardened outer cylinder and steel balls. Its components are made with high accuracy, so it can deliver precise motion control, along with higher loads and greater rigidity.
    2. Corrosion-and-rust resistance
      The linear bearing pillow block is made of galvanized aluminum alloy, well-designed and anti-corrosion. Hard chrome-plated shaft delivers anti-rust property.
    3. Easy bearing replacement
      Linear ball bearings adopt standardized design for easier and less costly replacement, less precaution and time-saving during assembly, characterized by distinct structure, compactness and light weight.
    4. Smooth and quiet operation
      Linear ball bearings have the lowest friction resistance as the steel balls loaded in the high tensile resin retainer are in point contact with the bearing housing. Therefore, the bearings can provide very smooth linear motion while reducing the noise.
    5. Long lifespan
      The friction coefficient of linear ball bearings do not change with the increase in load so as to ensure the long service time of the bearing even when working under heavy load. Note incidentally that LM linear ball bearings can deal with loads applied from any direction.
    6. Double-sealed Design
      ATO’s linear ball bearing adopt seals on both sides in order to prevent leaking of lubricant and avoid any exposure from environmental contaminants, suitable for use in places where there is a lot of dust or foreign objects are easy to invade.
    7. Energy-efficient and Able to increase motor performance
      The point contact between the balls and the bearing housing allows the steel balls rotate with very little frictional resistance, so that ball bearings do not have static friction to overcome before moving, enabling them to be energy-efficient and to obtain high-precision and smooth movement.
    8. Simple maintenance
      Save internal grease-lubrication of the bearing, making it easy for maintenance.
    9. Large operating range temperature ( -40 ~ 180 degree)
    10. Cost-efficient
      Featured with light weight, corrosion-resistance, easy replacement and low cost, linear ball bearings can help maximize the performance of various equipment in a bid to deliver best efficiency. Competitive prices lower their cost on the market.

    Simple, reliable, and highly effective, ball bearings are immensely valuable for reducing friction and wear while improving operational efficiency in all types of machinery.
