Linear carriage block QRW45 HCZAH HIWIN

QRW 45 HC ZAH HIWIN trolley

Linear trolley series RG and QR – Strength and precision in challenging conditions

Product description

Linear trolleys from the RG and QR series are technologically advanced solutions that utilize rollers instead of balls as rolling elements. Thanks to the linear contact surface, these trolleys offer exceptional stiffness and very high load capacity in all four directions of loading. These features make the RG series particularly recommended for applications requiring extreme precision and durability. Trolleys from the RG series are ideal for operation in harsh conditions, ensuring reliability and stability even under heavy loads.

Key features

·        Rollers instead of balls: Increased stiffness and load capacity with a compact design.

·        Linear contact surface: Reduction of deformations under load.

·        Load capacity in all directions: Stability and safety in mechanical systems.

·        Resistance to harsh conditions: Seals protecting against dust and harmful substances.

·        Low sliding forces: Efficient operation even under high pre-tension.

Typical applications

Linear trolleys from the RG/QR series are indispensable in:

·        Automation and transport technology.

·        CNC machines, such as gantry milling machines and grinders.

·        High-efficiency cutting machines and injection molding machines.

·        Electro-discharge machining machines.

·        Industrial devices requiring the highest stiffness and load capacity.

QR technology – additional benefits

The QR series combines the advantages of RG with SyncMotion™ technology, which provides:

·        Better running properties: Controlled movement of balls minimizes friction and generated noise.

·        Higher sliding speeds: Ideal for dynamic industrial applications.

·        Extended lubrication intervals: Reduced maintenance needs.

Design variants

·        RGH/QRH – high block trolleys designed for top mounting.

·        RGW/QRW – trolleys with flanges, allowing for mounting from both the top and bottom, increasing their versatility.

Why choose the RG and QR series?

·        Exceptional durability: Rollers instead of balls significantly increase resistance to loads.

·        Versatility of applications: Ideal for demanding industrial applications.

·        Stability and precision: Excellent for machines where accuracy and stiffness of operation are crucial.

·        Advanced seals: Protection against external factors increases the trolley's lifespan.
