SHELF LIFE AND STORAGE OF GREASE-LUBRICATED BEARINGS AND COMPONENTS To help you get the most value from our products, Timken provides guidelines for the shelf life of grease-lubricated ball and roller bearings, components and assemblies. Shelf life information is based on Timken and industry test data and experience. SHELF LIFE Shelf life should be distinguished from lubricated bearing/ component design life as follows: Shelf life of the grease-lubricated bearing/component represents the period of time prior to use or installation. The shelf life is a portion of the anticipated aggregate...

ENGINEERING BEARING TYPES AND CAGES TAPERED ROLLER BEARINGS TYPES AND CAGES SINGLE-ROW BEARINGS DOUBLE-ROW BEARINGS TDO - DOUBLE OUTER RING This is the basic and the most widely used type of tapered roller bearing. It consists of the inner-ring assembly and the outer ring. It is usually fitted as one of an opposing pair. During equipment assembly, single-row bearings can be “set” to the required clearance (endplay) or preload condition to optimize performance. This has a one-piece (double) outer ring and two single inner rings. It is usually supplied complete with an inner-ring spacer as a...

ENGINEERING BEARING TYPES AND CAGES TNASW - NON-ADJUSTABLE WITH LUBRICANT SLOTS TNASWE - NON-ADJUSTABLE WITH LUBRICANT SLOTS AND EXTENDED BACK FACE RIB These three bearing types are similar to the TDO with a one-piece (double) outer ring and two single inner rings. The inner-ring front faces are extended so they abut, eliminating the need for a separate inner-ring spacer. Supplied with a built-in clearance to give a standard setting range, these bearings provide a solution for many fixed or floating bearing applications where optimum simplicity of assembly is required. Types TNASW and...

ENGINEERING CAGES TAPERED ROLLER BEARING CAGES STAMPED-STEEL CAGES MACHINED CAGES The most common type of cage used for tapered roller bearings is the stamped-steel cage. These cages are mass produced from low-carbon sheet steel using a series of cutting, forming and punching operations. These cages can be used in high temperature and harsh lubricant environments. Machined cages for tapered roller bearings are robust in design and are suited for high-speed and high-load applications. Machined cages use alloy steels and are produced through milling and broaching operations. Assembly does not...

METRIC SYSTEM TOLERANCES METRIC SYSTEM TOLERANCES Tapered bearings are manufactured to a number of specifications with each having classes that define tolerances on dimensions such as bore, O.D., width and runout. Metric bearings have been manufactured to corresponding standard negative tolerances. Boundary dimension tolerances for tapered roller bearing usage are listed in the following tables. These tolerances are provided for use in selecting bearings for general applications in conjunction with the bearing mounting and fitting practices offered in later sections. The following table...
