Hubs and Bushings

CONVIBER offers a wide range of hubs and bushing systems for proper mounting of pulley to shaft. Included are Q.D. Hubs and Bushings (max. bore 12″), XT Hubs and Bushings (max. bore 12″), Taper-lock Hubs and Bushings (max. bore 12″) and keyless frictional locking assemblies (max. bore 23.622″). CONVIBER keyless locking assemblies are self-contained, high torque capacity units that feature no keyway stress concentration, no axial movement during assembly and high torque capacity. Keyless locking assemblies are used primarily with engineered class pulleys in high tension applications. Other means of securing the pulley to the shaft include press-fit and dead shaft designs. CONVIBER offers you total flexibility when it comes to mounting pulleys to the shaft.


Lagging for Conveyor Pulleys

CONVIBER has complete in-house pulley lagging capabilities. Every step of the pulley manufacturing and lagging process is controlled to assure quality, prompt delivery and competitive pricing of lagged pulleys. Available in a wide variety of styles and thickness, lagging is primarily used to improve tractive capacity, resist abrasive conditions and extend pulley and belt life. The style of lagging required is usually influenced by operating conditions. CONVIBER offers the following lagging styles: weld-on, plain vulcanized, herringbone grooved vulcanized, diamond grooved vulcanized, and rough top.


Ceramic Lagging FLEX-LAG® by Flexco

Flex-Lag Ceramic Lagging is designed for use in conveyor installations where belt slippage cannot be overcome by conventional rubber lagging. Eliminate belt slippage and achieve the highest coefficient of friction available in a lagging material – 2 to 3 times the friction of rubber in wet, dry or muddy conditions.


Craft-Lag® Replaceable Lagging

Craft-Lag is bonded to rigid backing which is then formed to a specific diameter. Craft-Lag can be used with or without retainers and is ideal for mining, crushed stone, sand and gravel, cement, agriculture, food processing, coal mining, power plants, feed and grain and general industry.
