Premium B6/30 2RS Bearing – 30mm – Triple Grub Screw – Go Kart

Premium 30mm bore axle bearing with triple grub screw locking for go kart rear axles. The three grub screw design provides a significantly more secure axle lock than standard single or double grub bearings — reducing the risk of bearing rotation on the axle under the hard braking and acceleration loads of a busy rental environment.

Bearing rotation on the axle is one of those failures that starts subtle and gets expensive quickly — a bearing that's working loose causes uneven wear, vibration, and eventually axle damage that costs far more to fix than the bearing itself. The triple grub screw configuration is a straightforward reliability upgrade over standard UC206 bearings for any operator who wants better axle retention without moving to a more complex bearing arrangement.

A worthwhile step up for high-use fleets where standard bearings are being replaced too frequently or showing signs of rotation wear on the axle.
