A block spindle has a rectangular body suited for mounting on a flat surface. The bearings sit directly in the rectangular body, offering a higher rigidity than the cartridge spindle design. Replacement of the spindle requires removal of the entire block from the machine and requires a tram upon re-installation. Unlike the cartridge spindle design, the back of the block spindle body is used to mount a belt box or an inline motor mount. Our block spindles are available in six series.
