iglide A350 - Temperature and wear resistant

Transcription

1 Compliant with both FD and EC Directive 10/2011 EC regulations Low moisture absorption Good with medium and high loads High temperature rating up to 356 F 447

2 - Temperature and wear resistant FD compliant, for medium and high loads Compliant with FD and EC Directive 10/2011 EC For use with temperatures up to 356 F very universal bearing for use in the area of food and pharmaceutical industries. Composition of FD compliant materials allows for use in areas where, due to the contact with food, other bearings cannot be used. With good tribological and mechanical properties, bearings are suitable for general purpose use in food machinery. For medium and high loads Equally good for both oscillating and rotating applications If FD compliance is required If wear-resistance and FD conformance is necessary at high loads If the bearing is used in an acid environment When temperatures are continuously greater than 356 F 500 When the maximum abrasion resistance is necessary J When a low priced FD bearing is required For high speeds J material complies with EC Directive 10/2011 EC and also with FD (Food and Drug dministration) specifications for repeated contact with food. vailable from stock Detailed information about delivery time online.

4 - Technical Data Temperatures Its temperature resistance makes an ideal material for a bearing in the area of foodstuffs. Typically, temperatures range up to +266 F, which corresponds perfectly with the applicable temperature range for. Short-term temperatures up to +410 F are possible. Please note that at temperatures over +284 F, the pressfit forces of the bearings may decrease and an additional axial securing device is recommended. The wear-rate of bearings rises only a little with higher temperatures. Tests have shown good wear results at +212 F on all tested shaft materials. pplication temperatures, Page 67 Pressure (psi) 11,600 8,702 5,802 2, Temperature in F Minimum Max. long-term Max. short-term dditional axial securing pplication Temperature -148 F +356 F +410 F +284 F Recommended maximum permissible static surface pressure of as a result of the temperature Temperature limits for Friction and Wear The coefficient of friction of on a steel shaft is in the mid range. The friction decreases at higher temperatures, which in dry operation is somewhat unusual.

5 - Technical Data Shaft Materials Corrosion-resistant steels are rather considered a natural choice for use in the food industry. Trials were therefore carried out especially on such materials. It has been shown that there is no clear favorite 440B and hard chrome plated steel are both suitable. Hard-anodized aluminum is also well suited for both linear and rotating movements. For a ground surface with an averge roughness of rms is recommended for the shaft.

Please adhere to the catalog specifications for housing bore and recommended shaft sizes. This will help to ensure optimal performance of plain bearings.
