Tangeseiki #1738 Headset Bearing 37x49x7 mm 45/45°

The Tangeseiki #1738 is a precision-engineered headset cartridge bearing designed for smooth and reliable steering performance. Built to exact tolerances, it ensures consistent alignment and dependable operation in demanding riding conditions.

Optimized 45° / 45° Contact Angle: Featuring a 45° / 45° angular contact design, this bearing delivers balanced load distribution between the frame and fork. This geometry enhances steering stability and helps maintain long-term headset performance under repeated stress.

Sealed Cartridge Construction: The fully sealed cartridge design protects the internal bearing races from dirt, moisture and contamination. This reduces maintenance requirements while extending bearing life, making it suitable for both road and off-road applications.

Compatibility and Fit: Sized for headsets requiring a 1.38" bearing standard, the #1738 is ideal for specific integrated or semi-integrated headset systems. It is intended as a direct replacement where precise fit and smooth rotation are essential.

Manufactured with Tangeseiki’s proven bearing expertise, this headset bearing delivers dependable performance and consistent steering feel, ride after ride.
