A pillow block bearing (or plummer block) is a mounting used to support a rotating shaft with the use of bearings and various accessories. The assembly consists of a mounting block which houses a bearing. [1] The block is mounted to a foundation, and a shaft is inserted, allowing the inner part of the bearing/shaft to rotate. [1]
A ball bearing. A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.
Spherical roller bearing with a brass cage in a cut-through view. A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring.
The tie plate increases bearing area and holds the rail to correct gauge. It is fastened to wooden ties by means of spikes or bolts through holes in the plate. The part of the plate under the rail base is tapered, setting the inboard cant of the rail, typically "one in forty" (or 1.4 degrees ). The top surface of the plate has one or two ...
A separate tap set and facing set is usually employed by frame builders where more robust tooling that is more frequently used is needed. Both tap sets and facing sets are intended for frame finishing work after welding and/or brazing, as the frame tubes tend to deform slightly after this process, and for cleaning out any weld splatter or paint ...
