⚙️ Product Overview

We supply a comprehensive range of rollers designed for float glass production lines, specifically for annealing lehrs from Zone A to Zone F. Our products are engineered for high-performance thermal environments.

Lift Out Roller (LOR) - Material: 25/20

Designed for long-term use in high-temperature zones. Features high temperature resistance, anti-oxidative properties, corrosion resistance, and high precision with no thermal bending.

Steel Roller - Material: 25/20, 18/8

Ideal for A2-B zones of float glass annealing lehrs. It offers excellent stability, a smooth surface, and a long service life under high-temperature conditions.

HRF 650 Non-Asbestos Heat-Resistant Roller

Wear-proof and scratch-free, providing good thermal stability for float glass annealing lines.

Composite & Graphite Ring Rollers

Utilized in cooling zones (below 260ºC to 400ºC). These rollers provide fast heat dissipation, are light-weight, and ensure scratch-free glass handling.
