Dimensions are the same as on each model page. Models without a complete bore, OD and width are not listed here; ask us for them.

Field bearings fail from dirt and water more often than from load. Choose the seal first: multi-lip contact seals for mud and dust.
For square or hex bores, send the across-flats size and the shaft length. A loose fit on a square shaft wears the bore.
Many agricultural models are matched to a machine part number. Send the part number, a photo of the old bearing and its markings.
Interchange is matched by dimensions and function and confirmed on your sample or drawing before we quote.

Send the machine make and model, the part number or the old bearing. We match the size and seal, confirm it on your sample or drawing, then quote.

Can you match a bearing from my machine part number?

Yes. Send the part number, a photo of the old bearing and its markings. We match it by dimensions and function and confirm on your sample or drawing.

Are square and hex bore bearings available?

Yes, on many sizes. Send the across-flats size, the shaft length and the seal you need.

Why do these bearings use special seals?

Field machines run in mud, dust, water and fertilizer. Multi-lip seals keep dirt out longer than standard seals.
