Описание Область применения: Для ограниченного пространства в поперечном направлении and high rigidity requirements Higher rigidity than SNS Значительно сниженные фрикционные колебания and low friction level, particularly under external load Максимальная точность Запатентованная зона входа increases the travel accuracy up to a коэффициент of six Features High rigidity in all load directions – permits applications with just one runner block per rail Высокая способность передавать крутящий момент Limitless interchangeability as all Ball Rail Systems can be combined at will with all Шариковая каретка versions within each accuracy class. Долговременная смазка is possible over several years End-face fastening thread for all attachments Quiet, smooth running thanks to optimally designed ball and ball chain return and guidance Different preload classes Отличные динамические характеристики Can be used on all SNS/SNO Шариковые направляющие Шариковая каретка pre-lubricated at the коэффициентy. Ball chain for низкий уровень шума level and best travel behavior Описание продукта Описание продукта of Ball Rail Systems Production description – Шариковая каретка Materials Selection of a linear guide acc. to DIN 637 Ball chain and seals Design and version Friction Due to the Rexroth design with four rows of balls, 2-point contact is available in all loading directions. This reduces the friction to a minimum. Other ball rail systems with two or four rows of balls with 4-point contact have multiple friction: due to the differential slip with lateral loading and in case of comparable prestressing without the load, the gothic raceway profile causes higher friction (depending on the raceway curvature and the load, up to five times the friction coefficient). This high friction leads correspondingly to greater heat. Seals Seals are use to prevent dirt, chips and coolants, etc. from working their way into the inside of he Шариковая каретка, thereby preventing reductions to its service life. For further information, see "Критерии выбора/seals". Standard seal (SS) Universal seals are fitted as standard in Rexroth Шариковые каретки. They have a uniform sealing effect for Шариковые направляющие with and without защитные ленты. Low friction and a good sealing effect have both been taken into account in the design. For applications where effective sealing is required. Low-friction seal (LS) For special requirements with regard to ease of movement. Double-lip seal (DS) For increased exposure to media Front seal For applications in environments with fine dirt or metal particles, as well as coolants or cutting fluids. Interchangeable during servicing. Front seals are available as accessories for mounting by the customer. уплотнение FKM For applications in extreme environments with fine dirt or metal particles, as well as heavy use of coolants or cutting fluids. Interchangeable during servicing. FKM переднее уплотнениеs are available as accessories for mounting by the customer. Cover plate wiper For use in environments with coarse dirt or chips.
