Quiet roller linear guideway are industrial components designed for low-noise, high-precision motion requirements. Their core feature lies in using rollers as the rolling elements and employing synchronous coupling technology to achieve quiet and smooth movement.

QR Series Linear Guideway Main Features
1. Low-Noise Design: The rollers are evenly arranged using a synchronous coupling, eliminating collision noise between adjacent rollers. Noise levels are reduced by approximately 3 decibels compared to traditional guides, making them suitable for noise-sensitive environments (such as electronics manufacturing and medical equipment).

2. High Load Capacity: Utilizing a DB (45°-45°) contact system, it can withstand high loads in four directions (vertical, horizontal, and vertical), making it suitable for heavy-duty applications (such as logistics conveying systems and large robots).

3. Smooth Motion: The synchronous coupling ensures simultaneous roller movement, reducing frictional resistance fluctuations and improving motion stability.

QR Series Linear Guideway Applications
1. Electronics Industry: Precision equipment requiring high speed, quiet operation, and low dust generation (such as semiconductor manufacturing equipment).
2. Heavy Industrial Equipment: Such as large robots and logistics conveying systems, relying on high load-bearing capacity and resistance to lateral forces.
3.Medical and laboratory equipment: Scenarios with stringent requirements for noise and precision.

Selection Recommendations

Compared to ball bearing guides: Roller guides offer higher load capacity but are more expensive. Selection should be based on a comprehensive consideration of load, precision, and budget.

QR series offers super high rigidity and very high load capacities. The QR series with SynchMotion Technology offerslow friction, smooth movement, guieter operation and longer running life. in the industry where high accuracy, lownoise and high rigidity is required, the QR series is interchangeable with the RG series.

Advantages Quiet Roller Type Linear Guideway Feature
1. Super high load capacity in linear guideway, with the four rows of rollersarranged at a contact angle of 45-degrees, the QR series linear guideway hasequal load ratings in the radial, reverse radial and lateral directions, The QRseries has a higher load capacity in a smaller size than conventional, ball-typelinear 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 elementscollision noise and sound levels are drastically reduced.
3. Smooth Movement in standard linear guideways, rolling elements on the load side of the quide block begin rollincand push their way through the raceway. When they contact other rolling elements they create counter-rotationafriction, This results in a great variation of rolling resistance, The QR linear quideway, with SvnchMotion’technology prevents this condition.
4. The QR series is a type of linear guideway that uses rollersas the rolling elements. Elastic deformation of the linearcontact surface, during load, is greatly reduced therebyoffering greater rigidity and higher load capacities in all 4 load directions.
