Gravity conveyor rollers 119, designed for pallet handling

Series 119 offering an ideal solution for smooth unit material handling. These rollers are indicated when load capacity is a priority as they can deal with very heavy freight, delivering optimal performance when combined with the 139 series. They are an excellent choice for logistics applications and especially intended for pallet handling but series 119 units can also be suitable for the transportation of packages.

Each roller is built with a steel tube, available with a diameter of 80 mm or 89 mm, swaged at the end, a feature that enables perfect coupling with the bearing housing. The 20 mm shaft is drilled and threaded as standard, designed for screw fitting, this detail enhances the rigidity and strength of the structure but also simple and safe installation.

The 2RZ rigid radial shielded ball bearings distinguish themselves for being permanently lubricated and housed in polyamide end caps which are further protected by polypropylene caps to secure longevity and optimal operation.

High performance and efficient gravity idle rollers for practical logistics

Thanks to the particular shape of the end caps, the type of bearings and the coupling accuracy, series 119 are also well-suited for driven and belt conveyors, bearing a broad range of speed. This model is specifically designed to work flawlessly with Rulmeca chain driven rollers series 139 offering reliable performance in a wide variety of industrial systems.

Referring to operating conditions, these rollers are designed to be used for environments having a wide range of temperatures from -5°C to +80°C. To employ the gravity conveyor rollers for operations outside this range a verification of the conditions of use and a custom configuration is required as well as it is recommended to verify operating conditions.

The materials that compose the 119 series are:

Tube: steel (unfinished or galvanised), stainless steel
End caps: PA (RAL 9005) and PP (RAL 1023), series 6205-2RZ ball bearings
Shaft: steel

Please note that other materials and/or finishes are available on request.

Main features

Smooth running pallet handling and sturdy structure

Series 119 is able to deal with massive load capacities and consequently these gravity conveyor rollers are the most efficient solution for the transport and support of large pallets and heavy cargos

Availability in stainless steel for hygienic applications

These rollers can be created with stainless steel, the well-known rust-resistant metal, making them well adapted to food-related applications: as processing and / or packaging, due to the simplicity of frequent cleaning and long-term corrosion protection

Strong and sophisticated steel tube of the gravity conveyor roller

Thanks to its swaged end caps that contain the polyamide, one of the strongest synthetic polymers, the result is that the product gains high strength, wear resistance, resistance to chemical substances and low friction operation

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.
