1.0 Technica! introdution / introduccion tecnica b) Limiting speed The speed limit is based on practical exprience and laboratory tests that takes into ac魭count the strength of the cage, lubrication, sealing function and centrifugal forces. Cages Fersa is able to supply cages made in different materials: - Pressed steel. - Synthetic materials such as polyamide PA 66. b) Limite de velocidad El limite de velocidad se basa en la experien-cia pr͢ctica y en las pruebas de laboratorio que toman en cuenta la solidez de la caja, el lubri-cante, la funcin de obturacin y las fuerzas centrifugales....
