FAG 7602017-TVP Schrägkugellager (17x40x12)

As an axial angular contact ball bearing, this bearing carries high axial loads at elevated speeds, e.g. for ball screws. At 17x40x12 mm and a unit weight of 0.06 kg, the installation envelope is fixed; further technical details are held in the specification table. In its open design this axial angular contact ball bearing stays accessible on both sides and is lubricated and sealed by the surrounding construction.

In the axial angular contact ball bearing the ball raceways sit at a contact angle to the bearing axis; the load line therefore runs at an angle, which yields high longitudinal forces at a higher permissible speed and greater axial stiffness than a flat thrust set. The design is normally run preloaded — often as an adjusted pair or set — because only the preload removes axial play and establishes the stiffness that feed axes and ball screws demand.

The open version has no seal of its own; lubricant supply, sealing and relubrication are handled by the surrounding construction, which eases relubrication intervals and installation in enclosed housings. Without seal friction the frictional torque stays low, so the power loss follows essentially from the preload and the quantity of lubricant.

Standard bearing steel is through-hardened and covers the usual operating-temperature range; for the design, axial force, preload, speed and the required stiffness should be assessed together.
