Product Description

European Standard aluminium alloy chill-casting hard oxidation flanged Flat Belt Pulleys for Taper Bushes 

V- belt pulley

V- belt pulley of different types ( according to type and width of belts). The material used is cast iron EN-GJL-250 CZPT EN 1561, and for only a few types it is steel C45 E CZPT EN 10083-1. They have a small prebore that can be machined  according to  customers’ requirements. Moreover the most common types are available also with taperlock bore.

V belt pulley specifications

Here are the most important specifications to consider when choosing a V-belt pulley:

• Center distance: This is the distance between the centers of the shafts that the pulleys are mounted on.
• Outside diameter: This is the diameter of the pulley measured across the outside edge.
• Groove width: This is the width of the grooves in the pulley.
• A number of grooves: This is the number of grooves in the pulley.
• Groove angle: This is the angle of the grooves in the pulley.
• Pulley material: This is the material that the pulley is made of.
• Pulley finish: This is the finish that is applied to the pulley.
• Pulley bearing: This is the type of bearing that is used in the pulley.
• Pulley keyway: This is the keyway that is used to mount the pulley on the shaft.
• Pulley hub: This is the hub that is used to mount the pulley on the shaft.
• Pulley flange: This flange mounts the pulley on the shaft.

Choosing a V-belt pulley that is the correct size and type for the application is essential. The pulley should be the correct center distance, outside diameter, groove width, number of grooves, groove angle, material, finish, bearing, keyway, hub, and flange. If the pulley is not the correct size or type, it may not work properly, or it may damage the equipment.
