TQI HGW 20CC RG LM Block | High-Precision Flange Type Linear Carriage

The TQI HGW 20CC RG is a premier Flange Type (HGW) linear motion carriage specifically designed for precision-heavy industrial environments. Engineered with a 'High Load' (CC) configuration, this block provides exceptional structural rigidity and optimized load distribution across its four rows of high-grade ball bearings. The wide flange profile allows for secure mounting from either the top or bottom, providing superior lateral stability compared to square types, making it the ideal choice for the primary axes of industrial CNC routers, bridge saws, and heavy automation systems. Manufactured from induction-hardened alloy steel, the HGW 20CC ensures smooth, low-friction travel and high repeatable precision even under demanding axial stresses. With integrated dust protection and a high-performance lubrication system, this block is built for long-term reliability in professional fabrication workflows.

Technical FAQ

What is the benefit of the Flange (HGW) type over the Square (HGH) type?

Flange blocks offer a wider mounting surface, which provides significantly better lateral stability. They also allow for mounting bolts to be secured from either the top or the bottom, offering more flexibility for heavy-duty machine frames.

Is this block compatible with other brands of rails?

While it follows standard HGR20 dimensions, we recommend using TQI LM rails to guarantee the precision ball track alignment and preload settings required for maximum longevity.

How do I maintain the lubrication of the HGW 20CC block?

The block features an integrated grease nipple. We recommend a lithium-based grease for standard industrial applications, with maintenance intervals every 100km of travel or every 3-6 months depending on debris levels.
