Upgrade your bicycle's performance with these premium hybrid ceramic ball bearings. These 6805 2RS bearings feature a robust chrome steel ring construction with advanced black ceramic (silicon nitride) balls, combining durability with superior performance. The bearings measure 25mm inner diameter, 37mm outer diameter, and 7mm width, making them ideal for precise applications. The dual rubber seals (2RS) protect against dust and debris while retaining lubrication. The nylon cage ensures smooth ball movement and proper spacing. These bearings excel in high-speed applications, offering reduced friction and outstanding wear resistance. Pre-lubricated with high-quality grease, these bearings are ready for immediate installation. Perfect for bicycle wheels, bottom brackets, and other demanding applications where traditional steel bearings might not meet performance requirements. The ceramic ball construction provides excellent durability and rotational performance, while the chrome steel rings ensure structural integrity.

  • PRECISION DESIGN: Hybrid ceramic ball bearing featuring 25mm inner diameter, 37mm outer diameter, and 7mm width for exact fit and performance
  • DUAL PROTECTION: Double rubber-sealed (2RS) design on both sides keeps lubricant in and contaminants out for extended bearing life
  • PREMIUM MATERIALS: Chrome steel rings paired with black ceramic (silicon nitride) balls provide superior durability and wear resistance
  • SMOOTH OPERATION: Nylon cage design ensures proper ball spacing and smooth rotation while maintaining optimal lubrication
  • VERSATILE APPLICATION: Ideal for high-speed bicycle applications and other mechanical systems requiring precise, low-friction movement
