The sleeve is an alloy steel forging, heat-treated and ground to a fine finish. The sleeve has a precision non-locking tapered bore, which fits on, and is keyed to, the tapered roll neck, thus becoming the bearing journal. Surrounding the sleeve is the bushing, fixed in the chock, which carries the radial load.
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.

A parts book, parts catalogue or illustrated part catalogue is a book published by a manufacturer which contains the illustrations, part numbers and other relevant data for their products or parts thereof. Parts books were often issued as microfiche, though this has fallen out of favour.
A flanged bushing is a sleeve bushing with a flange at one end extending radially outward from the OD. The flange is used to positively locate the bushing when it is installed or to provide a thrust bearing surface. [10] Sleeve bearings of inch dimensions are almost exclusively dimensioned using the SAE numbering system.
Roller bearings are the earliest known type of rolling-element-bearing, dating back to at least 40 BC. Common roller bearings use cylinders of slightly greater length than diameter. Roller bearings typically have a higher radial load capacity than ball bearings, but a lower capacity and higher friction under axial loads.
A slot-fill bearing has the advantage that more balls can be assembled (even allowing a full complement design), resulting in a higher radial load capacity than a Conrad bearing of the same dimensions and material type. However, a slot-fill bearing cannot carry a significant axial load, and the slots cause a discontinuity in the races that can ...
The lower half of the main bearings are typically held in place by 'bearing caps' which are secured to the engine block using bolts. The basic arrangement is for each bearing cap to have two bolts, but some engines may have four or six bolts per bearing cap (often referred to as "four-bolt mains" or "six-bolt mains" engines).
