Description
Custom Cleanroom Compatible Silicone Rollers — Particle-Free Non-Marking Conveyor Rollers
Why choose this cleanroom silicone roller?
Designed for particle-controlled environments such as wafer fabrication, medical device assembly, and precision optics handling. Each roller features a precision-machined aluminum or stainless steel core bonded with a specially formulated low-shedding silicone compound, providing excellent release properties, chemical resistance, and vibration damping. The non-marking surface prevents contamination on conveyed products, reducing cleaning frequency and protecting high-value goods.
Custom roller compounds (silicone with anti-static or FDA-grade options), hardness from Shore A 20° to 70°, and surface finishes (smooth ground Ra ≤0.4µm, textured) are available. Dynamic balancing tolerance is kept tight to support smooth running. ISO9001 certified, our rollers offer superior heat resistance (up to 200°C) and low compression set, which means longer service intervals and fewer replacements.
Typical applications: Clean conveyor systems, wafer handling, semiconductor equipment, medical device packaging, optical film processing, battery production lines, and sensitive electronics assembly.

Ratings: 1 = low, 5 = high. Silicone offers excellent heat resistance and non-marking properties but lower mechanical strength; for heavy-duty conveying, polyurethane or natural rubber may be preferred. For cleanroom conveyor applications, our silicone compound is selected specifically to minimize particle shedding and provide a smooth non-marking contact surface. Our factory can produce custom hardness from Shore 20A to 98A across various compounds, and we help you choose the best material for your specific application.
For example, when abrasive media such as glass or ceramic is involved, a polyurethane coating in the Shore A 85–95 range often provides longer service life, whereas silicone remains the preferred choice when non-marking contact and heat resistance are critical. This practical guidance helps you select the right elastomer for each roller position in a clean conveyor or wafer handling line.
