What You're Actually Buying
This is a matched bearing set — one tapered roller cone (368A) and its mating cup (362A), sized for a 2" ID shaft and 3.5" OD bore. That's the inner bearing position on a huge range of trailer axles (Dana, Meritor, Fruehauf spindles) and some medium-duty truck front and rear hub setups.
368A2 is just Timken's way of noting the assembly number for the cone/cup pairing — same physical bearing as the 368A cone paired with 362A cup, just how it shows up on some parts lists and OE cross sheets. Don't let the '2' throw you, it's not a different bearing.
Why These Numbers Cross
368A, 362A, SET403, and 368A2 all point to the identical bearing geometry — it's an industry-standard tapered roller size that's been used since these axles were new, so you'll see it stamped by Timken, cross-listed under Federal-Mogul/BCA as UVS0253, and packaged by aftermarket houses as BR368A or A1228V1348. Freightliner's own parts book lists it as 368ATRB for OEM service replacement.
Where guys get tripped up is assuming any '368' bearing is interchangeable — check the cup OD and cone bore with calipers before you order if the numbers on your old bearing are worn off or unreadable. Seal ID/OD and drum bore have to match too; a bearing that fits the spindle doesn't do you any good if the double-lip seal behind it doesn't seat right.
Ordering From Us
We keep SET403 in stock at the Tacoma counter — walk-in same day if you're local, or we'll ship it out same-day nationwide if you call it in before our cutoff. At $35.99 it's cheap enough to just replace the set rather than gamble on a half-worn cone.
Bring in the old bearing or give us the number stamped on the cup (usually etched right on the outer race) before you buy. Better yet, run your VIN or axle tag by us — takes two minutes and saves you a return trip if the spindle turns out to be a different size than you thought.
368A2 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 368A2. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Does 368A2 fit my Freightliner trailer axle?
Likely, if your spindle takes the 2" ID / 3.5" OD tapered bearing — Freightliner lists this exact bearing as 368ATRB in their service parts. Pull the old cup and check the stamped number against 368A/362A before you order, or give us your VIN and we'll confirm.
Is this the same bearing as UVS0253?
Yes — UVS0253 is Federal-Mogul/BCA's part number for the same 368A/362A tapered roller set. Different box, same bearing geometry. Confirm by matching bore and OD dimensions on your old part if the numbers are worn.
My old bearing just says 362A, no 368A — is that a problem?
No, that's normal. 362A is the cup, 368A is the cone — SET403 packages both halves together. If your old bearing only shows one number stamped, that's just because the cup and cone get stamped separately, not because it's a different set.
