High Precision Wear-Resistant Zirconia Ceramic Roller / ZrO2 Guide Shaft
PRODUCT DESCRIPTION
ZTA ceramic rollers combine the hardness of alumina with the toughness of zirconia, making them ideal for high-speed wire guiding applications requiring wear resistance, low friction, and long service life.
High strength Zirconia (ZrO2) – 2× stronger than alumina
Excellent wear resistance – perfect for high-frequency rotation & friction
Ultra-smooth surface – reduces abrasion and noise
High temperature stability – long lifespan in harsh environments
Corrosion-proof & chemical-resistant
Tight machining tolerance: ±0.01 mm
Long lifetime compared to metal rollers
Custom sizes available
