Versions K2 and N2: Robust Rollers with Crown Sprockets for Reliable Drive in Medium Load Applications

Versions K2 and N2 have all the characteristics of the GM series and have one or two crown sprockets welded to the shell. Drive can therefore be provided with either a tangential chain or links. Suitable for medium loads.

This series is intended for use in temperatures of between -20°C and +100°C. Lower minimum temperatures are admissible, subject to verification of the conditions of use.

Materials

Tube: steel (unfinished or galvanised).

End caps: galvanised steel, full-compliment or caged rigid radial ball bearings.

Shaft: steel (unfinished or galvanised).

Other finishes are available on request.

Main features
Smooth-running and sturdy

 

P1C and P2C driven rollers

 

Made entirely in steel

 

Optional

Flanges

For the rollers diameter 76 and 89 mm, aluminium flanges are supplied separately in a special kit, composed by 2 elements and complete with zinc plated fixing bolts to assemble them in different ways. Attention: the screws must be tightened by torque wrench = 13 Nm

Optional

PVC covered rollers

Although not special, information on this design is given. The rough or zinc plated steel tube “N” or “Z and J” rollers with “D” values as per table, can be covered with a soft, elastic and smooth surface (hardness 73 ShA) grey colour (RAL 9006) PVC (Polyvinylchloride) plastic tube, particularly resistant to chemical agents. It is normally used to protect the roller surfaces and mostly to avoid scratching painted, enamelled, smooth, etc. load, and in some cases to increase friction. The PVC lagging is simply fitted on the tube with excellent coupling thanks to elastic tightening. Application temperatures ranging from -10°C to +50°C.

Optional

PVC covered rollers + Round belts transmission

PVC-covered rollers with round belt transmission are a common solution in material handling systems, offering an efficient method for conveying goods. The PVC-covered rollers are designed to provide smooth, durable surfaces that reduce friction and wear, ideal for handling a variety of materials, especially those requiring gentle handling or increased grip. The round belt transmission works by transmitting power through a flexible, round belt, which runs over these rollers, efficiently driving the conveyor system. This combination ensures quiet, low-maintenance operation, enhanced traction, and reliable performance in light to medium-duty applications, such as in food processing, packaging, and logistics. The system's simplicity and adaptability make it suitable for a wide range of conveyor configurations.

Optional

Rilsan coating

Rilsan coated: heat treatment based on Rilsan Polyamide powders of light grey colour, with particular resistance characteristics to chemical agents and wear

Optional

Round belts transmission

A round belt transmission is a type of mechanical drive system commonly used in material handling applications. It consists of a round, flexible belt that transmits power between pulleys, typically made from materials such as rubber, polyurethane, or elastomeric compounds. Round belts are often employed in conveyors, sorters, and other machinery where smooth and quiet operation is essential. The round profile ensures low friction, high efficiency, and the ability to work in compact spaces. These systems are known for their simplicity, ease of installation, and ability to handle moderate power transmission in light to medium-duty applications.
