Version 138R, with adjustable friction, allows the thrust to be applied to packages to be set, irrespective of the weight of the items. These are therefore used when it is necessary to overcome external resistance to package motion, such as the presence of lateral guides against which the packages are required to/may slide.
They can be used in temperatures of between -5°C and +40°C. Packages can be moved at a speed of up to 0.5 m/s for all constructions, in accordance with the applied loads.
Materials
Tube: steel (unfinished or galvanised), stainless steel.
End caps and pinions: PA (RAL 9005) and PP (RAL 1023), steel, 6002-2RZ-series ball bearings (standard or stainless).
Shaft: steel (unfinished or galvanised), stainless steel.
Other materials and/or 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: 138
Plus
With pinion, interchangeable with driven rollers from the 135 series.
With pinions in polyamide or steel.
For critical applications.
Optional
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.
