Engineering Grade Ceramic Lagging Drive Pulley
The drive pulley transmits power for conveyors. To improve pulley life and traction, it is typically built with a larger diameter than other pulleys. Based on carrying capacity, drive pulleys are available in three categories: light duty, medium duty, and heavy duty.

The Engineering Grade Ceramic Lagging Drive Pulley is designed to deliver superior traction and an extended service life in demanding conveyor applications. Featuring high-performance ceramic lagging, this pulley provides excellent grip between the pulley surface and the conveyor belt, effectively preventing slippage and enhancing power transmission efficiency.
The ceramic tiles are embedded in a high-quality rubber matrix, combining the hardness and wear resistance of ceramic with the shock-absorbing properties of rubber. This design helps reduce wear on both the pulley and belt, lowers maintenance requirements, and improves the operational reliability of the conveyor system.
Constructed with precision-engineered steel shells and heavy-duty shafts, the pulley delivers excellent strength and stability under high loads. Its advanced sealing system protects internal components from dust, moisture, and contaminants, ensuring long-lasting, trouble-free operation even in harsh industrial environments.
Key Features:
High-performance ceramic lagging for maximum grip and minimal belt slippage.
Excellent wear, abrasion, and chemical resistance.
Combines ceramic hardness with rubber flexibility for shock absorption.
Heavy-duty steel construction for high load capacity and long-term durability.
Advanced sealing design to protect bearings and extend service life.
Suitable for mining, cement, quarrying, and bulk material handling applications.
