Steel bushing SP-xx-xx series

bushingbearing

SP bushings are similar to P bushings, but with top serrations to prevent rotation in soft materials. SP bushings are recommended in high-torque situations for materials such as magnesium, aluminum, masonite, or wood. Serrations also resist axial force to prevent pushing the bushing through the jig plate. The finish-ground OD below the serrations ensures accurate ID location. To order a specific standard bushing, select the basic part number below and add the desired ID drill size (as a 4-place decimal inch) on the Price & Availability screen. See Technical Information tab for Standard Drill Sizes. Standard prices apply only to bushings with a standard inch, number, letter, or metric ID size within the stated range. Long bushings with ID sizes marked * are counterbored according to ANSI standards for proper drill-bearing length. SP bushings have top serrations to prevent rotation in softer materials, such as magnesium, aluminum, masonite, or wood. Finish-ground OD ensures accurate ID location. Extremely long bushings with a small ID size (marked with an asterisk * in the tables below) are counterbored according to ANSI standards for proper drill-bearing length to eliminate binding and heat buildup. Add "-NCB" for applications that require these bushings without a counterbore: SP-26-16-.1875-NCB (Special)
