Sopko Mounting Brackets are made of aged cast iron to provide an anchor-like support for any 3" diameter cartridge spindle. Rigid by design, Sopko brackets feature a large surface area base plate for solid member contact. The accurately machined dovetail base provides positive alignment, easy positioning, and secure clamping for operator safety. A two bolt quick mount/dismount system keeps any spindle parallel to the mounting base during operation. The mounting bore is precisely finished for uniform clamping contact across the full diameter of the spindle for vibration-free operation.

Optional Accessories for
Sopko High Speed Attachment.

The Sopko High Speed Attachment provides higher speeds than would ordinarily be obtained with other spindles. Capable of being mounted in any position about its axis, the unit attaches quickly and easily to the spindle housing and is held securely by two clamping screws. The drive pulley assembly is mounted and balanced on a wheel adapter 00200. Made from quality alloy steel, heat treated for strength, and precisely ground to maximize surface contact, the variety of eccentric bushings increases the unit’s versatility. And Sopko quality does not stop with the High Speed Attachment, it extends right into the most varied selection of grinding quills available anywhere.
