7204 C P4A GA Angular Contact Ball Bearing 20x47x14mm 32000RPM High Speed for CNC Spindle

7204 C P4A GA Angular Contact Ball Bearing

The 7204 C P4A GA is a precision angular contact ball bearing designed for high-speed CNC machine tool spindles and electric spindles. With a 15° (C-type) contact angle and P4A precision tolerance, it delivers exceptional running accuracy at speeds up to 32,000 RPM under grease lubrication, making it the fastest bearing in the 72 series lineup.

Key Features

Ultra-High Speed: 32,000 RPM grease limit, 48,000 RPM oil limit — the highest in the 72 series for its size class.
P4A Precision Grade: Tight dimensional tolerances and low runout ensure smooth spindle operation at elevated speeds.
G5 Grade Steel Balls: Imported precision balls with consistent sphericity reduce vibration and extend service life.
Kluberspeed NBU15 Grease: High-speed lubricant factory-filled for optimal thermal stability.
Flexible Pairing: Supports DB, DT, TBT, and QBC configurations for tailored stiffness and load distribution.
