Watch an explanation of the Browning 5-Pack & 6-Pack Upgrades for a knee mill Bridgeport spindle, including how they compare to the standard 3-Pack (3 bearing) design.

Bill Murphy of C & M Precision Spindle illustrates the key differences between each upgrade, including who should consider the upgrade, when it's the optimal time to get the upgrade, and why someone would prefer one upgrade over the other. Key points of discussion include how more bearings affect the spindle’s cutting precision, overall lifespan, and efficiency.

Also included in the video are helpful tips about bearings, spindle care, and the origins of the Browning name in the 5-Pack/6-Pack Upgrade.
