Application overview

How Koyo bearings serve Electric Motors & Pumps

Electric motors, pumps, fans and compressors make up most general-machinery bearing demand. In this equipment bearings run at high speed, with low noise and long service intervals. Repair workshops need the right seal type, clearance and cage for drive-end and non-drive-end positions.

  • Keep drive-end and non-drive-end bearings apart on the order, because they often differ in type, such as a cylindrical roller bearing at the drive end and a deep groove ball bearing at the non-drive end.
  • Match seal or shield suffixes (ZZ, 2RS, open) and clearance (C3) to the original motor specification.
  • Use angular contact ball bearings in pairs where pump shafts carry steady axial thrust.
  • On variable-frequency drive motors, check whether insulated or electrically protected bearings are specified.

Your bearing list

How to write a bearing list for Electric Motors & Pumps

Give each line a shaft position, the full Koyo reference with suffix, and the adapter sleeve or housing that goes with it. That stops the two most common mistakes: wrong quantities and missing parts during a shutdown.

Tapered and spherical roller bearings laid out next to an opened industrial gearbox

Example list layout

1 line = 1 position

Field What to write Why it matters
Bearing position Equipment model, shaft, drive end / non-drive end, floating / locating Keeps mixed lists from producing wrong quantities or wrong positions
Full Koyo reference Base number plus the full brand suffix as marked on the bearing The suffix defines seal type, clearance and configuration
Sleeve / housing Adapter sleeve, housing and mounting component references, listed separately The complete assembly arrives together, with no missing parts at shutdown
Quantity & date Quantity per line, destination country and postcode, required date Lets the quote show stock, estimated lead time and shipping terms
What should I send if the bearing suffix is missing?+
Send a clear photo of the markings on the bearing, plus the equipment model and the bearing position. Mark which details still need confirming. We complete the configuration and assembly details before quoting, and any technical change needs your approval.
Can bearings and mounting components go in the same inquiry?+
Yes. List bearings, adapter sleeves, housings and other mounting components in one inquiry, each on its own line. You get one written quote for the complete assembly.

“They understand gearbox bearing arrangements. When we submitted a mixed list with floating and locating positions, they confirmed which Koyo series fit each shaft before quoting. No wrong deliveries in a year of orders.”
