RGH35CA Roller Linear Guide Block for Heavy Load CNC Systems

RGH35CA is a 35 size CA roller linear guide block for CNC machines and other heavy-load motion systems. Compared with ball type blocks, the roller structure provides line contact rather than point contact, which helps improve stiffness and running stability under load. In the 35 size series, RGH35CA has a block length of 124 mm, with a basic dynamic load rating of 57.9 kN and a basic static load rating of 105.2 kN. It is suitable for machine tools, grinding equipment, and other applications requiring stable linear motion, higher rigidity, and reliable load support. For replacement or new selection, rail series, mounting dimensions, preload grade, and accuracy grade should be confirmed before ordering.

To support accurate model selection, the code of RGH35CA can be understood as follows:

• RG: Roller type linear guideway series
• H: Square block type
• 35: Size 35 series (standard rail width WR = 34 mm)
• C: Heavy load
• A: Mounting from top

Common option suffixes:

• Z0 / ZA / ZB: Light, medium, or heavy preload
• H / P: High or precision grade

Optional Technical Conditions

• Available Preload: Z0 / ZA / ZB
• Available Accuracy Grade: H / P
• Typical Use: CNC machining centers, heavy-duty cutting machines, CNC grinding machines, injection molding machines, automation systems, and other equipment requiring high rigidity and high load capacity

Photo Reference: The images above show the actual block structure, machining details, and surface finish of the RGH35CA standard block design. For replacement or interchange, rail series, mounting dimensions, preload grade, and accuracy grade should be confirmed before order.

• Higher Rigidity: The roller contact design provides higher rigidity and load support than ball-type guide blocks, helping maintain stable linear motion under heavy load.
• Balanced Standard Block Design: As the CA standard block version in the 35 size series, RGH35CA provides a balanced combination of block length, rigidity, and load support. It has a block length of 124 mm, with a basic dynamic load rating of 57.9 kN and a basic static load rating of 105.2 kN.
• Service Life Support: Compared with ball-type structures, the roller contact design helps reduce stress concentration under load, which supports longer running life in demanding linear motion applications.
• Configurable Sealing: Standard protection includes end seals and a bottom seal. Additional sealing options such as double seals and scrapers are available for applications exposed to chips, dust, or coolant.

• CNC Machining Centers: Suitable for machining centers, plano millers, and other machine tools that require stable linear motion and higher rigidity under load.
• Heavy-Duty Automation Systems: Used in automation equipment and transport systems where reliable mounting support and heavy-load linear guidance are required.
• CNC Grinding and Cutting Equipment: Applicable to grinding machines and heavy-duty cutting machines that benefit from higher rigidity and load capacity.
• Injection Molding Machines: Suitable for molding equipment that requires reliable linear guidance under repeated load conditions.
• Electrical Discharge Machines: Also used in EDM and other systems requiring stable motion and rigid mounting support.

• Actual Product Photos: The photos shown on this page reflect the actual block structure, machining details, and surface condition of RGH35CA. Packaging method and surface protection can be confirmed according to order requirements.

  Tolerance and Assembly Control: Key dimensions, running parallelism, and assembly consistency are checked according to internal inspection standards. Available accuracy grades and preload options should be confirmed based on the required application conditions. The RG series provides multiple preload classes and accuracy grades for different working requirements.

  Supply and Delivery Support: Stock status can be checked quickly for standard models. For urgent replacement demand or project schedules, delivery options can be confirmed according to quantity, rail length, and machining requirements.

  Engineering Assistance: 3D STEP and CAD files are available for selected models. Our team can assist with cross-reference review, dimension checking, and replacement selection before order, especially for applications requiring stable heavy-load linear guidance.
