Silent Heavy-Duty Linear Guide Rail QHW20 QHH20 Linear Bearings And Rails

The QH series is a silent heavy-duty ball linear guide, based on a four column single arc tooth contact design, optimized for high-speed, high-precision, and low-noise scenarios. Its core adopts SynchMotion technology, which achieves uniform arrangement of balls through patented synchronous couplings, significantly reduces noise, and improves motion smoothness.

  • 제품 특징

    Low noise design

    Using synchronous coupling technology to evenly and equally arrange the balls, eliminating the sound of collision between the balls, reducing high-frequency noise by about 5 decibels, and improving the overall noise intensity in all speed ranges.  ‌

     

    Self lubricating design

    The synchronous coupling has a built-in oil storage space, which continuously provides lubrication for the steel ball during operation, reducing the frequency of replenishing lubricating oil and ensuring a long service life.

     

    Improved smoothness of movement

    All steel balls start almost simultaneously, eliminating the frictional resistance fluctuations caused by the load side steel balls moving first in traditional guide rails, and maintaining stable motion inertia.  ‌

     

    High speed performance

    The ball and synchronous coupling adopts a circular line contact design, effectively reducing frictional resistance and suitable for high-speed working conditions.  ‌

     

    Interchangeability design

    The slider and slide rail can be replaced separately to improve maintenance convenience, but the combination accuracy is slightly lower than non interchangeable models.
