RGW35HC Linear GuideProduct Description

The RGW35HC is a high-rigidity linear carriage engineered for demanding industrial environments. As part of the RG Roller Series, it utilizes precision-ground cylindrical rollers instead of traditional ball bearings. This design transitions the rolling interface from point contact to "line contact," significantly increasing the load-bearing surface and minimizing elastic deformation under heavy pressure.

The "HC" Elongated Advantage
The "HC" (Super Heavy Load) designation identifies this as the elongated body version of the 35mm series. By increasing the block length, the RGW35HC incorporates more rolling elements into the load-bearing zone, providing exceptional structural stability and vibration damping.
Bi-Directional Flange Mounting
The flanged (W-type) design offers a wide mounting footprint with pre-drilled holes that allow for secure bolting from either the top or the bottom. This makes it a preferred choice for heavy-duty CNC worktables and large-scale gantry axes requiring robust moment-load resistance and straightforward integration. Compatible with standard RGR35 rails.

Operating Principles

The RGW35HC utilizes an advanced roller recirculation system engineered to manage high-load linear travel with maximum motion fidelity.

1.Line-Contact Physics: As the carriage moves, multiple rows of cylindrical rollers travel along the rail's raceways. By distributing the load along a linear contact surface rather than a single point, the system minimizes local stress concentrations and resists structural deformation under peak stress.
2.Enhanced Stability: The elongated "H" block design houses a greater number of active rollers at any given moment. This expanded contact footprint provides highly stable load support, minimizing pitching (front-to-back rocking) during rapid acceleration and deceleration.
3.Endless Circulation: Precision-engineered resin end caps redirect the rollers at the end of the load-bearing zone, guiding them through internal return channels back to the starting point to maintain a continuous, low-friction loop.
4.Zero-Backlash Preload: Each unit is precision-preloaded at the factory to maintain continuous, uniform contact between the rollers and the rail. This eliminates internal clearance, providing rapid positioning response and high repeatability.
