Check sintered thrust washers by part number and dimensions before you order. Send your details to PM Distributors in Australia for a quote.

A worn thrust washer can turn a routine maintenance order into guesswork when the part number has faded or the old part has lost its original size. Sintered thrust washers are easiest to match when you confirm the part number and the main dimensions together, and that is the approach we suggest for any replacement order.

How Do You Match Sintered Thrust Washers by Part Number?

Copy the reference from the old part, equipment drawings or earlier invoices exactly, including every letter, number and suffix. Compare it with the listed dimensions on our products page, which includes tables for sintered bearings and bar, plus a Washers section. If you cannot find a match, send us your reference and measurements for review.

Which Dimensions Should You Confirm Before Ordering?

A size check is the quickest way to avoid ordering the wrong item. Confirm these details before you ask for a match:

• Inside diameter (ID): Measure the opening that fits over the shaft or locating feature, or use the original specification if you have it.
• Outside diameter (OD): Check the seat the washer sits in and any clearances around it.
• Thickness: A different thickness changes the axial spacing between parts, so compare it with the original instead of the worn part.
• Part number: Note the full reference, including any suffix.
• Application details: Share the machine type, shaft speed, load and lubrication if your records show them.

If the old washer is badly worn, a direct measurement may no longer show the original size. Drawings, manufacturer records or a known specification are more reliable in that case.

Why Does a Dimensional Match Still Need an Application Check?

A matching size does not prove that sintered thrust washers suit every operating condition. Our technical information page explains that bearing load capacity is judged by pressure and surface velocity, known as the PV factor, and that lubrication affects the figure. Immersion in oil and forced oil circulation permit higher values, while poor shaft finish, contamination, shock loading and misalignment lower them. For that reason we do not treat a size match as a guarantee of performance.

The same page refers to ASTM B438 for its bronze bearings. That standard covers porous bronze-base powder metallurgy bearings, including thrust bearings, and its appendices cover dimensional tolerances and operating information. It is a useful technical reference, but it does not replace checking the washer against your equipment.

What Should You Send with an Enquiry?

A complete enquiry saves time on both sides. A photo of the part on its own often leaves too much open, especially when the washer is worn or the markings have gone. Send the part number, ID, OD and thickness you have, plus the machine details above, and we will compare them with the products and technical data we publish.

PM Distributors supplies sintered thrust washers alongside sintered bearings, bar and metal powders. Contact us with your part number and dimensions to request a quote or call us if you would rather talk it through.
