Linear cart series RG and QR – Strength and precision in
difficult conditions
Product description
The linear carts from the RG and QR series are advanced technological solutions that use 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 ideal for operation in difficult 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 carts from the RG/QR series are indispensable in:
· Automation and transport technology.
· CNC machines, such as gantry mills or grinders.
· High-efficiency cutting machines and injection molding machines.
· Electrical discharge machining machines.
· Industrial devices requiring maximum 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 – flange carts, 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 stiffness of operation are crucial.
· Advanced seals: Protection against external factors increases the cart's lifespan.
