Free rollers, also known as idler rollers, are a type of roller or wheel that are not driven by a motor or other power source, but are able to freely rotate. They are typically used to guide, support, or position a load or material, and are often used in conjunction with powered rollers, such as drive rollers or conveyor rollers, to ensure smooth and stable movement of the load.

Free rollers are commonly used in conveyor systems, as well as in material handling equipment such as cranes, hoists, and lift trucks. They can be used to guide a load or material through a machine or process, or to support a load or material as it is being moved.

Free rollers can be made from a variety of materials, such as steel, plastic or rubber, and are typically designed to be durable and able to withstand heavy loads and high levels of wear and tear.

There are different types of free rollers available depending on the application, such as:

Ball bearing free rollers, which use bearings to reduce friction and improve the rollability of the roller.

Grooved free rollers, which have a grooved surface to help keep a belt or chain in place.

Friction-free rollers, which are designed to reduce friction and increase the efficiency of the movement.

Free rollers are a critical component in many industrial and manufacturing processes, and they play an important role in ensuring the smooth and safe movement of loads and materials. Regular maintenance and replacement of worn or damaged free rollers is important to prevent equipment breakdowns and ensure the longevity of the equipment.
