6803 Steel Bearing for Hub

6803 Steel Bearing for Hub characteristics:

• Black Oxide Coating. Black oxide surface treatment increases raceway surface hardness and helps protect the bearing against humidity, oxidation and micro-corrosion. It improves resistance to corrosion and supports longer-lasting performance in demanding riding conditions.
• High-Performance Bearing Grease. Formulated to deliver low friction, excellent resistance to water and weather conditions, and stable lubrication over time.
• Optimized Internal Clearance. Engineered to absorb assembly tolerances and temperature-related expansion inside the hub, helping maintain smooth rotation and maximize bearing life.
• Controlled Dual-Contact Sealing. Dual-contact sealing helps protect the bearing from water, dust and external contamination without excessively compromising rotational smoothness.
• High-Precision Steel Balls. Steel balls are designed to provide reliable load capacity, consistent rolling performance and long-term durability for demanding hub applications.
• Performance Focus. Designed for smooth rolling, durability, corrosion resistance and efficient power transfer in demanding cycling conditions.

Dimensions
17 mm inner diameter x 26 mm outer diameter x 5 mm width.
