A retrofit to circular knitting machines that stabilizes the cylinder to reduce or eliminate wobbling or other undesired motion so that the machine can operate at a significantly higher speed. The cylinder is stabilized by a bearing system added to the knitting head of the machine. The bearing system includes a pair of tapered roller bearings, one of the bearings being disposed above the other one, and the directions of taper of the two bearings generally being opposite each other. An inner race of each bearing is affixed to the cylinder and an outer race of each bearing is affixed to a bearing housing that is secured to the stationary base plate of the knitting head. The tapered roller bearings help stabilize the cylinder so that its rotation axis remains essentially immovable and vertically oriented.
