TimkenEE540502/541162Tapered Roller Bearing Cone and Cup Set – Straight Bore, 5.0000 in ID, 11.6250 in OD, Open, Without Snap Ring

Product Description

What this part is

Timken EE540502/541162 single-row tapered roller bearing set in the TS (tapered single) imperial series, supplied as a matched cone and cup. Bore 5.0000 in (127 mm), cup outside diameter 11.6250 in (295.275 mm). Case-carburized alloy steel rings and rollers with a stamped steel cage, open on both faces, no snap ring in the cup outside diameter.

Decoding the designation

In Timken imperial nomenclature the number ahead of the slash is the cone — the inner ring with its roller and cage assembly — and the number behind it is the cup, the separate outer race. Here the cone is EE540502 and the cup is 541162. The EE prefix marks the extra-extra-light dimension group within the 540000 series, giving a comparatively thin cross section for the bore size. No precision suffix is present, so the set is standard Class 0 tolerance.

What these specs mean in practice

A tapered roller bearing carries radial and one-direction axial load through the same set of rollers, with the load line passing along the roller taper to an effective centre inside the bearing envelope. Dynamic radial rating is 270 kN (60,700 lbf) and static radial rating 485 kN (109,000 lbf). The stamped steel cage suits general industrial speeds and is the standard construction for this size. Working temperature range for the material and cage combination is −54 °C to 120 °C.

Quantity and configuration

One cone and one cup, the complete two-piece set for a single bearing position. Sale unit is 1 Pc.

Fitting notes

Tapered roller bearings of this type are mounted in opposed pairs and set to a target endplay or preload during assembly, the cup being adjustable in its housing bore or against a spacer. Cone and cup are matched at the raceway angle, so the pair ships and installs together.

Interchange guidance

The same designation is published by other makers to the same ISO envelope: SKF EE 540502/541162, NTN 4T-EE540502/541162 and Bower EE540502/541162 are direct interchanges. Bearings sharing the 5 in bore in a different dimension group are related sizes rather than substitutions, since the cup outside diameter and load ratings differ.
