Versions 8P and 8Q of driven rollers with pulleys for toothed belts are supplied on request and have the same basic characteristics and configuration combinations as the 135 series. They have pulleys for toothed belts that are interchangeable with the other pinions and pulleys from the other versions of 135 rollers. The Z20 8-mm-pitch pulley is made in black POM, requires the use of 11.2-mm-wide Polychain GT belts and similar, and is compatible with corresponding HTD belts. It is necessary to strictly comply with the specifications of the belt manufacturer in order to calculate drive, roller pitch and tolerance, in accordance with pretensioning if present.
Materials
Tube: steel (unfinished or galvanised), PVC (RAL 7037), stainless steel.
End caps and pinions: PA (RAL 9005) and PP (RAL 1023), POM, 6002-2RZ series ball bearings (standard or stainless).
Shaft: steel (unfinished or galvanised), stainless steel.
Other materials and/or finishes are available on request.
The most suitable material handling components for conveyors for those seeking robust and flexible solutions that allow for rapid sorting.
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.

Where it is necessary to increase friction between the rollers and the handled unit loads the employment of these sleeves are particularly effective. They are made with transparent Polyurethane 75 Sh.A with longitudinal grooves and are supplied separately only for rollers with tube Ø 50.
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.
