Rulmeca operates a Service centre fully dedicated to the repair and assembly of Motorized Pulleys
The 119 series is comprised of rollers that are extremely smooth-running for the loads permitted, and which can be perfectly combined with the 139 series. They are particularly suitable for application in the field of logistics, specifically for pallet transportation but also applicable for the transportation of packages.
The steel tube, available with a diameter of 80 mm or 89 mm, is swaged at the end, ensuring a perfect coupling with the bearing housing.
The 20-mm shaft is drilled and threaded as standard, designed for screw fitting.
This ensures simple assembly and contributes to the overall rigidity of the structure.
The 2RZ rigid radial shielded ball bearings, with permanent lubrification, are housed in polyamide and protected by polypropylene caps.
The particular shape of the end caps, the accurate coupling and the type of bearing used all render these rollers applicable for driven and belt conveyors, at a wide range of speeds.
Use is normally consented in temperatures of between -5° to +80°C; for use in other temperatures, verification of the overall conditions of use is necessary.
Materials
Tube: steel (unfinished or galvanised), stainless steel.
End caps: PA (RAL 9005) and PP (RAL 1023), series 6205-2RZ ball bearings.
Shaft: 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.
Material handling components that guarantee rapid, fluid and precise transportation.
Plus
Ideal for gravity conveyors for heavy loads.
With polyamide end caps.
For frequent cleaning and food-related 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.
