Tapered steering bearing 32906 for KuKirin G4

Smooth handlebar rotation with 32906 tapered bearing

The 32906 tapered roller bearing for the KuKirin G4 consists of an inner ring with cage and rollers, and a separable outer ring. Together, they form a bearing assembly for the appropriate headset. The separable design allows for installation of the outer ring and inner assembly in the intended sequence.

Features and dimensions

• Bearing designation: 32906.
• Design: tapered roller bearing with separable outer ring.
• Outer diameter: 47 mm.
• Weight: approx. 69.6 g.
• Vehicle model: KuKirin G4.

When choosing, compare the designation of the old bearing and its seat. Use the new inner assembly with its matching outer ring; do not combine a worn outer ring with new rollers.

Inspection and installation

• First, check for play, catching, or rough rotation along with the headset adjustment. Replace a bearing with worn raceways along with its outer ring.
• Clean the bearing seat, check the contact surfaces, and observe the prescribed lubrication. When pressing in, apply force to the ring being inserted without striking the rollers.
• After assembly, adjust the preload according to the vehicle's manual. The handlebar should move smoothly without any play; over-tightening does not eliminate wear.
