FAG 234414-M-SP Schrägkugellager (70x110x48)

As an axial angular contact ball bearing, this bearing carries high axial loads at elevated speeds, e.g. for ball screws. The mounting dimensions are 70x110x48 mm and the weight is 1.5 kg; technical details beyond these are shown in the specification table. For ball screws and comparable feed axes, this version is intended as a stiff, axially loadable guide.

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. Solid brass cage — Dimensional/form-fit equivalent — verify suffix-level details for critical applications. Matching suffixes are also listed by SKF (M, MA, MB), NSK (M) and NTN (L1, G1, M).
