2-697920/P2
Gamet Tapered Roller Bearing
Ultra-precision P2 grade matched pair bearing set with Gamet's renowned hollow roller design. ABEC-9 equivalent accuracy for the most demanding high-end machine tool spindle applications.
2-697920/P2 / Gamet Tapered Roller Bearing
The 2-697920/P2 is a premium Gamet-brand tapered roller bearing set manufactured to P2 precision grade -- equivalent to ABEC-9, the highest standardized bearing precision classification. Gamet bearings are renowned worldwide as the gold standard for machine tool spindle applications, where their unique hollow roller and flange-guided cage design delivers unmatched running accuracy, thermal stability, and vibration damping characteristics. This matched pair set provides ultra-high precision support for the rear (non-tool) end of high-performance machine tool spindles.
Tapered roller bearings inherently provide high radial and axial load capacity in a compact envelope, and the Gamet design elevates this capability through precision-matched roller sets, optimized internal geometry, and rigorous quality control. The P2 tolerance class ensures dimensional accuracy measured in sub-micron increments, with runout and tracking errors held to the absolute minimum. These bearings are specified by leading machine tool builders worldwide for spindle rear support in high-end turning centers, grinding machines, and multi-axis machining centers where spindle accuracy directly determines workpiece quality.

Why Choose 2-697920/P2 Gamet Bearings
Gamet bearings represent the pinnacle of spindle bearing engineering. Each feature is purpose-designed to deliver measurable performance advantages in the world's most demanding machine tool applications.
P2 Ultra-Precision
ABEC-9 equivalent grade -- the highest standardized bearing precision classification. Dimensional accuracy and runout held to sub-micron tolerances, ensuring the spindle accuracy that directly determines final workpiece quality.
Hollow Roller Design
Gamet's signature hollow roller geometry provides superior vibration damping and thermal stability compared to solid rollers. Reduced roller mass lowers centrifugal forces at high speeds while maintaining full load capacity.
Gamet Quality
Manufactured to Gamet's exacting specifications with proprietary internal geometry, precision-matched roller sets, and rigorous quality control. The gold standard brand for machine tool spindle bearings worldwide.
Matched Pair Preload
Factory-matched pair with uniform preload distribution ensures consistent performance when both bearings are installed. Eliminates on-site preload adjustment and guarantees optimal spindle running accuracy.
High Combined Load
Tapered roller geometry inherently provides high radial and axial load capacity in both directions. The optimized internal design handles the combined loading typical of spindle rear support positions.
Thermal Stability
The hollow roller design combined with flange-guided precision cage delivers exceptional thermal stability during sustained high-speed operation. Minimal heat-induced preload variation preserves accuracy over long production runs.
