7914CTYNSULP4

Engineered for the uncompromising world of high-speed spindles, the 7914CTYNSULP4 is more than just a component; it's a solution for high-frequency vibration and heat issues. This P4-grade angular contact bearing features a 70mm bore and 100mm OD, hitting that "sweet spot" for CNC precision where stability is paramount. The 15° contact angle (C-type) is a deliberate choice for axial rigidity, allowing it to maintain sub-micron accuracy even as RPMs climb. If you are dealing with tight tolerances in grinding or milling heads, this unit's P4 precision ensures the kind of predictable run-out that generic bearings simply can't match.

What sets the 7914CTYNSULP4 apart in a production environment is its TYN (Polyamide) resin cage. Unlike standard cages that struggle with friction at high velocities, this material is designed to stay cool, extending your machine's MTBF (Mean Time Between Failure). Being a Universal Single (SUL) bearing, it eliminates the headache of complex matching-you can pair them in back-to-back or face-to-face configurations straight out of the box with consistent preload. From precision lathes to high-load hydraulic pumps, it provides a rugged yet refined interface that handles combined loads without the typical thermal expansion seen in lower-grade alternatives.
