The slotted bearings mount into the  front jaw of the VX20F vise. The slotted bearings have a machined slot which fits closely to the clamp shafts. The close fit limits vertical racking and simplifies construction of the front jaw. Simply drill 2-1/2′ diameter counter bores to accept the bearings and fasten with the included mounting screws.
Includes two slotted bearings and mounting screws. Vise jaw, hand wheel, wooden hub and handle and single handle cap not included.
