A maintenance manager I dealt with last month was replacing bearings on a production line every six weeks, and what finally fixed it was switching to these washers — the spring tension holds the assembly tight even under constant vibration, so teh bearings last longer between rebuilds.
We run HPLC to verify the materail composition, and carbon steel versions come in with a tensile strength of roughly 1200 MPa or so, while the stainlss steel ones are typically around 800 MPa but handle moisture better, and all dimnesions are checked against DIN 42013 tolerances using a micrometer (usually within 0.05mm).
They're fine for small motor ball bearings and general machinery, but don't use them in high-tempearture environments above 200°C unless you've got the Dacromet coating, because the plain black oxide finish will break down pretty quickly there, and the zinc plating is better suited for indoor application anyway.
The zinc plated ones have a slight yellow tint from the passivation step — most buyers go with those for cost reasons, but the hot dip galvanized is thicker if you need outdoor corrosion protection.
Also, our company can mix surface finishes in one order if you're testing different treatments, but the MOQ is negotiable so just tell us what you need, and we usually ship within 30-40 days (check lead time on large quantities).
Standard orders usually take 30-40 days from order confirmation. If you need it faster, let us know and we can check our schedule.
Yes, we can mix surface finishes in a single order, but the MOQ per finish may apply. Just tell us the quantities you need for each treatment.
Sure, we can supply mill certificates for the stainless steel and carbon steel materials on request. Just mention it when you place the order.
The MOQ is negotiable, so we can work with you based on your needs. For small trial orders or large volumes, just reach out and we'll find a solution.
We package them in customizable cartons and pallets to suit your handling and storage. You can specify your preferred packaging details when ordering.
