Timken56650Taper Roller Bearing Cup 6-1/2″ OD 1-1/16″ W Single Row Imperial

Product Description

What this is
A Timken 56650 tapered roller bearing cup — the outer ring only, 6.500 in outside diameter and 1.0625 in wide. A tapered roller bearing comes apart into two pieces that are sold and stocked separately: the cone, which is the inner ring with the rollers and cage already assembled onto it, and the cup, which is the hardened outer ring the rollers run against. This listing is the cup. There is no cone, no rollers and no cage.

That is the normal way these are bought. A cup presses into the housing and a cone presses onto the shaft, and the two wear at different rates, so a shop replacing a bearing often needs only one half — or needs a spare cup on the shelf because the housing bore is the part that gets scored. Original Timken carton, still in its factory wrap, never installed.

How the part number breaks down
56650 — a Timken cup number in the imperial single-cup range. Timken’s inch tapered numbering is a catalog index rather than a dimensional code: the digits do not decode to the bore or the outside diameter the way a metric bearing number does. The size has to be looked up, which is why the dimensions are spelled out above and below rather than inferred from the number.

Cups and cones are numbered in separate ranges, so a five-digit Timken number beginning 5 does not pair with one beginning 3 by any rule — the matching cone for any given cup comes from Timken’s assembly tables. Also written 56650C and 56650-2.
