    Definition for PQR Aligning Linear Rails

    Same with roller type linear guides except for bearing the high load from all directions and high rigidity, as well as adopt the SynchMotion TM technology connector, can reduce the noise, rolling friction resistance, improve operation smooth and prolong the service life. So the PQR series have wider range of industrial applications, suitable for industrials which require high speed, silent and high rigidity .

    Advantage for PQR Series Best Linear Rails

    1. The driving rate is reduced, because the linear guide rail movement friction is small, as long as there is little power can make the machine move, the driving rate is reduced, and the heat generated by friction is more suitable for high-speed, frequent start and reversing movement.
    2. High action accuracy, the movement of the linear guide rail is achieved by rolling, not only the friction coefficient is reduced to one-fiftieth of the sliding guide, but also the gap between the dynamic static friction resistance will become very small, so as to achieve stable movement, reduce shock and vibration, can achieve positioning, which is conducive to improving the response speed and sensitivity of the CNC system.
    3. Simple structure, easy installation, high interchangeability, the size of the linear guide rail can be kept within the relative range, the slide rail installation screw hole error is small, easy to replace, install the oil injection ring on the slider, can directly supply oil, can also be connected to the oil pipe automatic oil supply, so that the machine loss is reduced, can maintain high-precision work for a long time.

    PYG® Technology has accumulated technology with years of experience, and its linear guides have high precision and strong rigidity, which can easily replace similar Japanese, Korean and Bay products.

    Advantage of sliders

    1. Our linear guide blocks  are equipped with appropriate clipper to reduce friction and prevent steel balls from falling, so that ensure  the machine can operate more safe  and stable,

    2. For special working conditions, our slides can also be made in high temperature and corrosion resistant styles;

    3. Our sliders are interchangeable,If you only need to replace the slider, tell us the size you need and we can match it well for you.

    Block types:

    There are two types of block: flange and square, the flange type is suitable for heavy moment  load application because of the lower assembly height and wider mounting surface.

    Adequate Supply

    We can ensure on-time delivery and large requirements for ball bearing carriages and guide rails.

    Excellent Service

    We offer professional pre-sales, sales, after sales service and technology consultation.
