Altis Delta Steering Roller Bearing | Upper or Lower Steering Stem Bearing | By Altis Powersports

The Altis Delta Steering Roller Bearing is a genuine OEM replacement tapered roller bearing from Altis Powersports, designed specifically for the Altis Delta and Altis Delta S. These bearings are used within the steering stem assembly, supporting the upper and lower triple clamp while allowing smooth, precise steering movement through the frame's head tube.

Available for the upper or lower steering stem position, these bearings are critical to maintaining proper steering feel, front-end stability, and rider confidence. Genuine Altis Powersports bearings are manufactured to factory specifications, ensuring proper fitment and compatibility with the original steering stem and frame assembly.

Over time, steering stem bearings can wear from normal riding, impacts, water intrusion, and lack of lubrication. Worn bearings can cause rough steering, unwanted play in the front end, or a notchy feeling when turning the handlebars. Replacing worn bearings helps restore smooth steering performance and proper front-end control.
