Key features
- Angular contact bearing 45° x 45° for combined radial and axial loads
- Double 2RS sealing for protection against water and contaminants
- High precision and smooth rotation
- Compact design for integrated headset systems
- Compatible with 1"1/4 steerer tube
Description
Angular contact headset bearing with 45° x 45° configuration, designed to provide stable interface between fork and frame and balanced load distribution. The dimensions 36.8 x 45.8 x 6.5 mm make it suitable for integrated headset systems with 1"1/4 steerer tubes. Steel construction with ground raceways ensures smooth and precise rotation, while seals on both sides retain lubrication and prevent contamination, supporting long term durability.
