Double Roller (U-Groove) for Normal Systems

Description

Wika U-Groove Sliding Rollers | Precision Engineering for High-Performance Systems

In sliding aluminum systems, the roller acts as the heart of the mechanism. The Wika U-Groove Double-Wheel Roller is precision-engineered to eliminate common system failures—such as rattling, rail abrasion, and misalignment—ensuring silent, fluid operation for modern residential and commercial projects.

Specialized U-Groove Design: Stability in Every Motion

The geometry of our U-profile wheels is engineered for a seamless interface with round or flanged tracks in standard aluminum profiles. This symmetric alignment delivers:

• Elimination of Lateral Play: Prevents sash vibration and derailment during operation.

• Uniform Load Distribution: Evenly distributes the weight of heavy glazing across the rail, mitigating friction and premature profile wear.

The Power of the Tandem Wheel System

For contemporary projects featuring oversized sashes and heavy-duty double glazing, single rollers often fail under mechanical torque. The Wika Double-Wheel system provides two independent, self-aligning contact points:

• Load Capacity up to 120kg: Robust, reliable support for standard-to-tall sashes.

• Sealing Integrity: By effectively preventing sash drop, our rollers ensure gaskets remain perfectly compressed, maintaining optimal thermal/acoustic insulation and preventing dust ingress.

• Seamless Operation: The tandem wheel configuration ensures consistent, smooth movement, even in the presence of minor track debris.

Engineering Selection Guide

Performance is strictly tied to the ratio between sash weight and roller capacity. Choosing an undersized component inevitably leads to binding, rail damage, and loss of sealing.

• Light Sashes: Single-wheel assembly (up to 70kg).

• Standard/Medium Sashes: Double-wheel assembly (up to 120kg).

• Heavy/Floor-to-Ceiling Sashes: Quad-wheel assembly (up to 200kg).

Pro Tip: For tall sashes, higher torque requires a higher safety factor. We recommend selecting a roller capacity that exceeds your total sash weight by at least 15-20% for maximum longevity.
