The QRH-35-CA-ZA-H in Brief

The HIWIN part number QRH-35-CA-ZA-H is a QR Series Linear Guide Block. The QRH-35-CA-ZA-H is compatible with 35 mm QR (RG) Series Guide Rail. It is suitable for heavy load duty and has a square type mounting surface that can accept mounting bolts through the top of the mounting surface. To help maintain precision for many industrial applications, the QRH-35-CA-ZA-H has a medium preload and high-level precision grade (in relation to other QR Series blocks).

QR Series – Roller Type Linear Guideway, with SynchMotion® Technology

QR series offers super high rigidity and very high load capacities. The QR series with SynchMotion® Technology offers low friction, smooth movement, quieter operation, and longer running life. In the industry where high accuracy, low noise and high rigidity is required, the QR series is interchangeable with the RG series.

Advantages and Features

  1. Super high load capacity in linear capacity in linear guideway, with the four rows of rollers arranged at a contact angle of 45-degrees, the QR series linear guideway has equal load ratings in the radial, reverse radial, and lateral directions. The QR series has a higher load capacity in a smaller size than conventional, ball-type linear guideways.
  2. Low Noise Design With SynchMotion® technology, rolling elements are interposed between the partitions of SynchMotion® to provide improved circulation. Due to the elimination of contact between the rolling elements, collision noise and sound levels are drastically reduced.
  3. Smooth Movement In standard linear guideways, rolling elements on the load side of the guide block begin rolling and push their way through the raceway. When they contact other rolling elements they create counter-rotational friction. This results in a great variation of rolling resistance. The QR linear guideway, with SynchMotion® technology prevents this condition.
  4. The QR series is a type of linear guideway that uses rollers as the rolling elements. Elastic deformation of the linear contact surface, during load, is greatly reduced thereby offering greater rigidity and higher load capacities in all 4 load directions.

Construction of QR Series

  • Rolling circulation system: Block, Rail, End Cap, Circulation Path, Rollers, and the SynchMotion®
  • Lubrication system: Grease Nipple and Piping Joint
  • Dust protection system: End Seal, Bottom Seal, Cap, Double Seals, and Scraper
