This linear motion shaft is 20 mm in diameter and 55" long, chrome plated, and case hardened, and is suitable for use with linear support blocks and closed type slide units in linear motion applications. The high-carbon steel shaft is chrome plated for corrosion resistance, case hardened for wear resistance, and precision ground for consistent ball bushing radial clearance. The shaft diameter and length are specified for accurate fit and this shaft is suitable for use in applications, such as measuring systems, printing equipment, and computer numerical control (CNC) tools.
Mounted bearings combine a bearing mounted inside a housing unit. The bearing housing replaces the need for a casting or weldment to position the bearing securely for reliable operation, and its design determines the type of insert bearing. Insert bearings use rolling elements (ball, cylindrical, spherical, barrel, needle, spindled, or tapered) to maintain the separation between moving parts to reduce rotational friction, and to support radial and axial loads. Available in a variety of materials and mounting configurations, mounted bearings can be one- or two-piece, they can have an extended inner ring and locking device, and they can have seals and end caps that retain lubrication and protect the working parts of the bearing from environmental debris. Mounted bearings support shafts in a variety of mounting configurations (flange block, hanger, pillow block, and take-up block), and are used in a range of applications from light duty shaft guidance on conveyors to road building equipment and crushers.

I've purchased a couple of these rods in the past. I found some that were a little shorter than these, and about half the price of these rods. I got some of them because I needed shorter rods for my rock tumbler that I built.I have since purchased more of these more expensive rods, because they are straight. If the rods/rollers are bent, they you get the effect of the gap that the rubber barrels ride on getting wider and narrower as they rotate. This will translate into premature wear on the barrels. At this point, I have 14 barrels at a cost of around $20 each. It doesn't take long to close the gap in price between the cheaper rods and the more expensive ones when you start having to replace barrels more often.Quality components = quality machines = better value and less maintenance cost in the long run.This is a good product (for now). Pay the money, and get quality components the first time.
