Medium duty rollers

Product catalog summary

Overview: The document provides technical specifications and guidelines for the use of medium duty idle rollers, specifically series 307 and 308, suitable for straight and curved roller conveyors handling medium and heavy loads, even in dusty environments.

Specifications:

Rollers are made of steel tubes with CH17 key attachment or M10 bored and tapped shaft for easy assembly.
Precision radial rigid bearings type 6202 are used.
Standard rollers have sealed bearings type 6202-2RS with additional type 1 protection, while CH17 key attachment rollers have open bearings with grade 6 protection (Ermex C6).
Rollers are greased for normal temperatures ranging from -10°C to +90°C.

Designations:

The designation includes the code, possible executions on request, and the letter L followed by the length in mm.
Example: 308134J.M10 L500 indicates a Roll D 50 with a 15 mm bored and tapped shaft M10.

Technical Data:

Weight calculation formula: Pr = L · a + f [kg], where L is the length, a is the weight per mm, and f is the fixed weight.
Minimum and maximum lengths vary by model, with L min. ranging from 70 mm to 80 mm and L max. from 1600 mm to 2200 mm.

Load Capacities:

Tables provide load values for a rated life of 10,000 hours. For longer life, loads should be reduced by a coefficient C.
Loads are affected by tube deflection relative to roll length.

Additional Notes:

All dimensions are subject to machining tolerances.
DUGOMRULLI reserves the right to modify products without notice.
Reproduction of the catalogue's illustrations and text is prohibited.

Le tabelle seguenti riportano i valori già calcolati per una durata di progetto di 10.000 ore. Per una durata superiore ridurre i carichi moltiplicandoli per il coefficiente C. I carichi stampati in rosso sono limitati in funzione della lunghezza, dalla flessione del tubo. Durata [h] C MEDIUM DUTY IDLE ROLLERS RATED LOADS The following tables show the loads of the rollers for a rated life of 10.000 hours. For longer rated lives loads are to be reduced by multiplying by “C” coefficient. Loads printed in red depend on the tube deflection, in relation to the roll length.
