BOWER BS 225977 High-Precision Angular Contact Ball Bearing | 30x62x16mm | Spindle Grade | P4 Class

The BOWER BS 225977 is a specialized high-precision angular contact ball bearing engineered for demanding industrial applications requiring extreme rigidity and minimal runout, such as machine tool spindles, high-speed routing equipment, and precise positioning systems. This bearing is constructed with ultra-clean steel, featuring a tailored 40-degree contact angle (Alpha) optimized for supporting both heavy axial and significant radial loads simultaneously. The design minimizes internal friction and heat generation, ensuring thermal stability even during sustained high-speed operation (up to 12,000 RPM limiting speed when grease-lubricated). Its premium cage design facilitates efficient lubricant distribution and reduced noise levels, making it the benchmark choice for critical rotational applications. As a core component of precision machinery, the BS 225977 guarantees P4 (ABEC 7) tolerance levels, meeting the stringent requirements for superior accuracy and extended service life. Choosing BOWER means investing in reliability; these bearings undergo meticulous inspection processes to ensure consistent quality, delivering exceptional stiffness crucial for maintaining cutter accuracy in CNC environments. Utilize the BOWER BS 225977 to achieve optimal performance, reduce maintenance downtime, and ensure the highest surface finish quality in your most sensitive automation and manufacturing processes.

Key Features

  • P4 (ABEC 7) Tolerance: Ensures extremely tight dimensional and runout control for maximum operational accuracy.
  • High Rigidity 40° Contact Angle: Provides exceptional axial stiffness essential for tool position maintenance and vibration dampening.
  • Composite Phenolic Cage: Optimized for high-speed performance and reduced heat generation under dynamic loads.
  • Pre-Greased and Sealed: Delivered with long-life, high-performance grease, minimizing installation and maintenance complexity.
  • Optimized Internal Geometry: Designed for low noise operation and extended service intervals in critical applications.
