Product catalog summary
Introduction
This document provides technical specifications for the Series 306 idle rolls, which are pre-lubricated and protected with semi-precision bearings. These rolls are primarily used in intermittently operating flat belt conveyors with light loads and low speeds.
Specifications
The rolls are equipped with semi-precision bearings and are suitable for operating temperatures between -10°C and +90°C. They are designed for easy interchangeability with heavier series rolls using CH17 attachments.
Dimensions and Weights
A table on page 3 lists the standard dimensions and weights, as well as custom dimensions available upon request. The rolls are typically supplied with blank piping.
Designation
The complete designation includes the code number, finish, lubrication reference, and the letter 'L' followed by the length in mm. Examples include 306018.C5.L608 and 306018.C5.ZN.PV L608.
Load Capacity
The document provides tables showing the load capacities of the rollers for a rated life of 10,000 hours, with adjustments for longer life spans using a coefficient C.
Additional Information
All dimensions are subject to machining tolerances. DUGOMRULLI reserves the right to modify products without notice, and reproduction of the catalogue's content is prohibited.

La tabella seguente riporta i valori già calcolati in funzione di n e di L, per una durata di progetto di 10000 ore. Per una durata superiore, ridurre i carichi moltiplicandoli per il coefficiente C. Codice Code The tables below show the loads of the rollers for a rated life of 10000 hours as a function of the R.p.m. n and the length L. For longer rated lives loads are to be reduced by multiplying for C coefficient.
