Versions LD and LS are free-wheeling driven rollers with all the main characteristics of the GL range. The application of the free-wheeling sprocket to one end of the roller allows the roller to be driven in only one direction, with either clockwise or anticlockwise drive rotation (to be defined on configuration). The shell is free to move like an idle roller in just one of the two directions. The free-wheeling mechanism is screwed onto a dedicated housing that contains 6201-size bearings.
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 rigid radial ball bearings.
Shaft: steel (unfinished or galvanised).
Other finishes are available on request.
Material handling components for conveyors capable of guaranteeing high performance and the full functionality of the system.
An application that demands high performance requires a wide and high-quality range of material handling components for conveyors.
The term "Product execution" refers to a product variant that may differ in certain characteristics: material, type of transmission, capacity, size, etc.
It's base product is: GL

The LD and LS series rollers feature a free-wheeling sprocket on one end, allowing the roller to drive in only one direction, with a selectable clockwise or anticlockwise rotation. The shell moves like an idle roller in the opposite direction
These rollers are designed for use in a temperature range of -20°C to +100°C, with lower minimum temperatures being possible depending on the usage conditions
The rollers are made with steel tubes (unfinished or galvanized), galvanized steel end caps, and full-compliment rigid radial ball bearings. The shaft is also steel (unfinished or galvanized), with other finishes available upon request

Double rollers are a type of conveyor component used in material handling systems, consisting of two parallel rollers mounted on a single shaft. This design provides increased load-bearing capacity, enhanced stability, and smooth operation for the movement of materials. Double rollers are commonly employed in applications where higher strength or support is required, such as in heavy-duty conveyors, or for ensuring even distribution of material across the conveyor system. They are especially effective in preventing misalignment, reducing friction, and improving the overall efficiency and longevity of the conveyor system.
Double rollers with PVC-covered rollers are commonly used in material handling systems, particularly in conveyor applications. These rollers consist of two parallel shafts, each mounted with a set of rollers, providing enhanced stability and support for the conveyed materials. The PVC covering on the rollers offers several benefits, including increased durability, improved grip, and reduced friction, making them ideal for handling various types of materials, including lightweight, fragile, or delicate products. The combination of double rollers and PVC covers ensures smooth and reliable operation, even in demanding environments, while minimizing wear and tear on both the rollers and the conveyed materials.
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.
Rilsan coated: heat treatment based on Rilsan Polyamide powders of light grey colour, with particular resistance characteristics to chemical agents and wear
