Rollers series 307

Product catalog summary

Overview: The document provides technical specifications and guidelines for the Series 307 rollers, which are designed for light and medium-duty belt and gravity conveyors. These rollers are suitable for use in challenging environmental conditions.

Specifications: The rollers are equipped with 6202 bearings, greased for life, and protected by ERMEX C6 seals that offer waterproof and wear-recovery features. They are compatible with conveyor brackets and transoms detailed in chapters M10 and M11.

Dimensions and Weights: A table on page 3 lists the lengths and weights of standard and custom sizes. The CH17 attachments allow for interchangeability with rollers from other series.

Lubrication and Temperature Range: The rollers are pre-lubricated for normal temperatures ranging from -10°C to +90°C. They can also be lubricated for extreme temperatures: TB (-30°C to -10°C) and TE (+90°C to +150°C). Special materials may be required for extreme conditions.

Denomination: The full designation of the rollers includes the code number, finish, lubrication reference, and the letter 'L' followed by the length in mm. Examples include 307017.ZB L608 and 307011.ZB.PV L608.

Weight Calculation: The weight of a roller (Pr) can be calculated using the formula: Pr = L · a + f [kg], where 'L' is the length, 'a' is the weight per mm, and 'f' is the fixed weight.

Rated Loads: The document provides a table showing the rated loads for a lifespan of 10,000 hours, based on R.P.M. and roller length. For longer lifespans, loads should be reduced using a coefficient 'C'.

Key Data from Tables: The tables provide detailed information on roller dimensions, weights, and load capacities. For example, the weight per mm for different codes (307011, 307012, 307013) is 0.0043 kg, 0.0051 kg, and 0.0057 kg, respectively. The fixed weight 'f' varies from 0.389 kg to 0.524 kg depending on the roller code.

RULLI SERIE 307 Molti anni di positiva esperienza permettono di indicare questi rulli come i più adatti per trasportatori a nastro leggeri e medi, anche in cattive condizioni ambientali. Sono montati su cuscinetti 6202, lubrificati a vita ed efficacemente protetti dalle sperimentate protezioni ERMEX C6, che contengono una tenuta stagna con recupero d’usura. II montaggio al trasportatore avviene con l’ausilio dei supporti e delle traverse presentate nei capitoli M10 e M11. A pagina 3 la tabella riporta lunghezze e pesi delle dimensioni standard e di quelle costruibili a richiesta. Gli attacchi...

La tabella seguente riporta i valori già calcolati in funzione di n e di L, per una durata di progetto di 10.000 ore. Per una durata superiore, ridurre i carichi moltiplicandoli per il coefficiente C. Codice Code The table below shows the loads of the rollers for a rated life of 10.000 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. RATED LOADS
