Linear carriage block QRH25 HAZAH HIWIN

QRH 25 HA ZAH HIWIN cart

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

Product description

The linear carts 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 carts 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. The carts from the RG series are ideally suited for operation in harsh conditions, ensuring reliability and stability even under heavy loads.

Main 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 carts from the RG/QR series are indispensable in:

·        Automation and transport technology.

·        CNC machines, such as gantry mills or grinders.

·        High-performance cutting machines and injection molding machines.

·        Electrical 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 carts designed for top mounting.

·        RGW/QRW – carts with flanges, allowing for both top and bottom mounting, 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 rigidity of operation are crucial.

·        Advanced seals: Protection against external factors increases the lifespan of the cart.
