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.
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: GM
Plus
Optional
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
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
