Q: How do these guides prevent kickback?
One-way bearings in the rollers let stock feed forward freely but resist any backward movement, which is what drives kickback toward the operator.
86N4290 - JessEm Clear-Cut Table Saw Stock Guides

By keeping work registered against both the fence and the surface of the machine table, these stock guides improve safety and accuracy on a table saw or shaper.
To restrict lift, the fence-mounted guides are spring tensioned to keep them set snug against the top of the stock. The rollers also have a 5° feed bias that helps draw the work inward, keeping it fully registered against the fence.
The wear-resistant urethane tires provide good traction on the work, and one-way bearings ensure the correct feed direction to help prevent kickbacks.
The guides pivot for height adjustment, with a maximum stock capacity of 13/16" above the mounting surface, and extend up to 2 3/4" from the face of the mounting bracket. Infeed and outfeed rollers can be spaced up to 22 3/4" apart.
The paired guides are set in an included 30" long aluminum T-track extrusion that mounts permanently to the top of most fence models that use a square steel tube or extrusion with 1/4" T-slots.
Largely made from anodized aluminum and stainless steel, the guides have excellent fit and finish. Mounting screws, a drill bit for pilot holes, a T-25 Torx driver and a 1/8" hex key are included. An effective way to greatly improve stock control.
For owners of the Incra fence, an accessory mounting kit is available separately.

They install using the included 30" aluminum T-track extrusion, mounting screws, a pilot-hole drill bit, a T-25 Torx driver, and a 1/8" hex key.
In most cases, yes, since the T-track mounting system is designed to attach to a standard fence or table surface rather than one specific saw brand; these table saw stock guides are built to be broadly compatible.
