Brand: Martin


This Martin quick disconnect idler bushing is made of high carbon steel for strength and resistance to wear. Idler bushings have ball bearings and attach to sheaves or sprockets to create free spinning idlers for adjusting the tension of belt drives. The idler bushing has two permanently lubricated ball bearings that require no maintenance. It works with stock V-belt drives, sheaves, sprockets, timing belt pulleys, and other components that fit quick disconnect bushings. Drive components can be removed without dismounting the bushing. This steel idler bushing has an operating temperature range of -48 to 248 degrees F (-44 to 120 degrees C), and is used for tensioning belt drives, which are found in automobiles and various industrial power transmission applications.

Plain bearings provide low-friction sliding contact for relative motion between parts of a machine. They are the simplest type of bearing, with no rolling elements, and there are three basic types of plain bearings: radial plain bearings (also called sleeve bearings or bushings) to support rotating or reciprocating shafts, thrust bearings (also called washers) to support axial loads on shafts, and linear bearings to support and guide the motion of parts in a straight line. Flanged sleeve bearings have a flange on one end to support axial loads. Spherical plain bearings are radial bearings that allow for angular misalignment of the shaft. Plain bearings are made from durable, low-friction materials such as sintered or cast bronze alloys, plastic, or a combination of a metal shell and a plastic bearing surface. They can be lubricated externally or by a lubricant embedded in the bearing material. Plain bearings are used in automobiles, construction and mining equipment, textile manufacturing equipment, and robotics, among others.

Right up front, Mark comes across as very honest and dependable. I took my lawn tractor to him to take a look at after another shop quoted me a high price to fix my motor after they had it sit in their shop for 2wks. He diagnosed/repaired it in less than a week. Also save me some money. I would definitely recommend him and his shop, and will be coming back to him for any more small engine work that I may have in the future.
