7602 High-precision Ball Screw Bearings With Double Seals

The 7602 high-precision ball screw bearings with double seals have undergone preload adjustment and are easy to install on machinery. They are equipped with a bearing cage made of resin material. Compared with previous angular contact ball bearings, more steel balls are incorporated, which enhances the stiffness. There are both contact-type seals with excellent sealing performance and non-contact-type seals that can reduce the loss torque and keep the temperature rise low. When used in pairs, they can withstand axial loads, radial loads, or combined loads.

Dentail

High stiffness: Compared with traditional angular contact ball bearings, more steel balls are incorporated. The increase in the number of steel balls makes the force distribution among the steel balls more uniform when the bearing bears loads, effectively enhancing the overall stiffness of the bearing. During the cutting process of a heavy-duty CNC machine tool, in the face of large cutting forces, the 7602 bearing can stably support the screw, prevent it from excessive deformation, ensure the precise positioning of the cutting tool, and guarantee the machining accuracy.
Good sealing and heat dissipation performance: The double seal structure can not only prevent impurity invasion but also control frictional heat generation, achieving a perfect balance between sealing and heat dissipation. For example, in food processing machinery, facing humid, dusty, and frequently washed working conditions, the 7603 bearing, with its excellent sealing performance, avoids the damage to the bearing caused by water and impurity. At the same time, its low temperature rise characteristic ensures the hygiene and safety of the food processing process, reducing the risk of food contamination due to overheating of the bearing.
Easy to install: The preload-adjusted characteristic makes installation simple and fast. Professional technicians do not need to spend a lot of time on-site for preload debugging. Ordinary workers can complete the installation according to the standard process, greatly improving the assembly efficiency of the equipment, especially suitable for the rapid assembly and maintenance of equipment on a large-scale production line.
