Описание Область применения: Для высоких требований к жесткости Сверхпрочная шариковая каретка for heavy machine construction with extremely high load-bearing capacity Максимальная жесткость во всех направлениях нагрузки Повышенная жесткость при отрыве и боковой нагрузке conditions due to two additional mounting screw holes at the center of the Шариковая каретка Высокая способность передавать крутящий момент Features Attachments on the Шариковая каретка can be mounted сверху and below Долговременная смазка is possible over several years Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection Quiet, smooth running thanks to optimally designed ball and ball chain return and guidance Steel Шариковая каретка body with corrosion-resistant coating, matt silver finish, hard chrome plated Шариковая каретка pre-lubricated at the коэффициентy. 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. Cover plate wiper are available as accessories for mounting by the customer. Технические характеристики Грузоподъемность и моменты нагрузок Size 55 65 C N 109000 172000 C0 N 174000 280000 M
