Guide roller bushings are used to adjust the clearance between a guide roller and its track via an eccentric mounting hole. The B-1 bushing has a roller diameter of 0.550 inches, a hex head size of 7/16 inch, an inner diameter of 0.1873 inch, and an eccentric adjustment range of 0.012 inch. It is available in carbon steel with electroless nickel plating or 304 stainless steel. The standard height is 0.440 inch, with a low-head variant available at 0.080 inch height. The bushing features a knurled face to resist slipping after adjustment.
Modern Linear Bushings are used in conjunction with our guide rollers to facilitate mounting and incorporation into a rolling carriage. The concentric bushing, also referred to as stationary, acts as a stand-off and compliments the spacing of the eccentric, or adjustable bushing. Most applications utilize a combination of both adjustable and non-adjustable bushings.Modern Linear adjustable bushings incorporate a unique feature designed to improve performance. The face of the mounting surface is knurled to resist slipping once locked into place. This feature improves the holding ability of the bushing and guide roller once it has been adjusted, eliminating bushing slip, a leading cause of maintenance in this type of linear system. This is especially helpful in applications where vibrations are present or loads are shifting.Customer supplied fasteners are used to create the carriage assembly. The adjustable bushing has an offset hole for the fastener. The offset from the center line equals the maximum distance of adjustability. The minimum adjustable range is 0.012 inches for the size 1 bushing, and the maximum adjustable range is 0.060 inches for the size 4XXL bushing. Modern Linear guide roller bushings are designed to accept common fasteners. When assembled, the hex head is turned to adjust the fit of the guide roller to the track. The fasteners are tightened down to lock the bushing in place, when ideal fit is achieved. When possible, concentric bushings should be positioned to carry the majority of the load. This offers maximum versatility of carriage design.The adjustable and stationary bushings are available for each of the five guide roller sizes. Standard bushings are made from 4L12 steel with an electroless nickel plating. 304 stainless steel bushings are also available. Standard height bushings are designed to accept a standard open-end wrench to make adjustments. Low head bushings are available for compact applications.Additio
