Machinery Company supplies genuine Koyo / JTEKT bearings and mounting parts to gearbox, drive and maintenance buyers worldwide. Here are the questions buyers ask most.
Send a clear photo of the markings on the bearing, the equipment model and the bearing position. Note which items still need confirming, such as seal type or clearance. We complete the identification before issuing a quote.
Yes. Bearings, adapter sleeves, housings and related mounting components can go in one inquiry. List each mounting part as a separate line with its reference, so the full assembly is quoted together and nothing is missing at shutdown.
Substitute references are listed separately on the quote, never swapped silently. Tell us whether you accept alternatives when you inquire. Any technical change requires your approval before the order is placed.
Bearings ship in original Koyo packaging with certificates and full documentation. The written quote names the product documents for your order, alongside model, quantity, price and currency, stock status, estimated lead time and quote validity.
Send the full reference, bearing position, quantity, destination country and required date. Machinery Company confirms the suffix and configuration, then replies with a written quote.
