GROUP 01
Designation and suffix questions
The correct SKF motor bearing is identified by its complete designation, including every seal and clearance suffix, not by its size alone. Send the full marking, or a clear photo of it, together with the motor model and bearing position.
Purchasing engineerWhat information identifies the correct SKF motor bearing execution?
What information identifies the correct SKF motor bearing execution?
The full designation with all suffixes, the bearing position, and the motor or machine model. Suffixes define the seal or shield type and internal clearance, so they decide which execution is quoted.
Also include adapter sleeve or housing designations, quantities per line, destination country and postcode, and the date you need the goods.
Purchasing engineerDistributor buyerWhy isn't an abbreviated stock code enough to order from?
Why isn't an abbreviated stock code enough to order from?
Internal stock codes usually drop the suffixes that record the original seal type and clearance. If you order from the short code, you can end up with the wrong execution.
Copy the designation from the bearing itself or from the OEM parts list. For repeat orders, quote the same full designation each time so every delivery matches the last one.
Maintenance supervisorIf the dimensions match, why can the bearing still be wrong?
If the dimensions match, why can the bearing still be wrong?
Matching bore, outside diameter and width only tells you the bearing fits. It doesn't tell you it will work. The equipment specification may call for a particular sealing, clearance or bearing design that a size match can't confirm.
Send the full designation and the application, and the execution is confirmed before quoting.
Maintenance supervisorThe marking is worn. Can I send a photo instead?
The marking is worn. Can I send a photo instead?
Yes. Attach a clear photo of the bearing marking and say which details you still need confirmed. Identification is finished before any price is quoted, so an incomplete marking doesn't turn into a wrong order.
| Item | Why it matters |
|---|---|
| Equipment / machine model | Ties the bearing to the assembly it fits |
| Full designation + suffixes | Sets the seal or shield type and the clearance |
| Bearing position (DE / NDE) | Stops position mix-ups and wrong quantities |
| Adapter sleeve / housing | Makes sure the assembly is complete |
| Quantity per line | Lets you check each line against your list |
| Country, postcode, required date | Needed for freight, tax terms and the estimated lead time |
GROUP 02
Shaft position questions: DE and NDE
Put each motor bearing position on its own line, drive end (DE) and non-drive end (NDE), with its own full designation and quantity. Repair lists that merge the two ends are a common cause of wrong quantities and wrong fitting.
Maintenance supervisorHow should I list a motor's two bearing positions?
How should I list a motor's two bearing positions?
One line for DE and one line for NDE, each with the full designation read from that position. Don't assume both ends match. Many motors pair a deep groove ball bearing with a cylindrical roller bearing.
Maintenance supervisorDistributor buyerHow do I write DE/NDE quantities for several motors?
How do I write DE/NDE quantities for several motors?
Give the quantity for each position separately: bearings per motor at DE and at NDE, times the number of motors. Never write a single combined total. You can then check each quoted line against your repair list.
Maintenance supervisorShould adapter sleeve and housing designations go in the same enquiry?
Should adapter sleeve and housing designations go in the same enquiry?
Yes. If a position uses an adapter sleeve, housing or bearing unit, include its designation. Before quoting, we check the assembly is complete, so nothing is missing on the day of the shutdown.
"A pump motor failed at our water treatment plant. We needed SKF bearings for both shaft positions. They confirmed the drive-end and non-drive-end bearings, shipped the same day, and the pump was back in service within the week."
GROUP 03
Application questions: pumps, fans and VFD motors
Tell us the application in your enquiry and application-specific points can be flagged before quoting. These answers are guidance only. They are not a technical guarantee, and final bearing selection stays with your engineer or the equipment manufacturer.
Maintenance supervisorPurchasing engineerWhat should I state for angular contact bearings in a pump?
What should I state for angular contact bearings in a pump?
The complete designation, with every suffix that defines the execution, plus the pump position. Angular contact ball bearings carry combined loads, so the execution matters as much as the size.
This is a reminder about what to send, not a selection recommendation.
Maintenance supervisorWhat should a fan drive enquiry include?
What should a fan drive enquiry include?
Every position in the drive train: the motor bearings, the fan shaft bearings, and any housed supports or bearing units. Larger fan assemblies may use spherical roller bearings, while auxiliary drives often run on bearing units. List each one with its housing or sleeve.
Maintenance supervisorPurchasing engineerMy motor runs on a VFD. Should I consider insulated bearings?
My motor runs on a VFD. Should I consider insulated bearings?
Raise it in your enquiry. Shaft currents in VFD-driven motors can cause premature bearing failure, and the original specification may call for an insulated execution with a specific clearance.
Insulated SKF bearings are quoted on request once the execution is confirmed. This is a prompt to check, not a technical guarantee.
"When we asked about a VFD-driven motor, they flagged the shaft current risk and supplied insulated SKF bearings with the right clearance. No premature failures since."
GROUP 04
Alternative designations and technical changes
An alternative is never swapped in silently. Any alternative designation appears as its own clearly marked line on the quote, and no technical change goes ahead without the buyer's approval.
Purchasing engineerHow is an alternative designation shown on the quote?
How is an alternative designation shown on the quote?
It gets its own line, labelled as an alternative and placed next to the designation you asked for. You can compare the two and accept or reject it line by line.
Say in your enquiry whether separately marked alternatives are acceptable at all.
Purchasing engineerDistributor buyerWhy must the buyer approve every technical change?
Why must the buyer approve every technical change?
Because you own the equipment specification and live with the result. A change to seals, clearance or design affects how the assembly runs and whether it passes your own checks.
Written approval also keeps repeat orders consistent and your records ready for audit.
GROUP 05
Written quote and ordering questions
Every order starts from a written quote that states designation, quantity, price and currency, stock status, estimated lead time, validity and freight and tax terms. Payment and commercial terms follow the quote, and lead times are estimates, not fixed promises.
Distributor buyerWhat does the written quote include?
What does the written quote include?
Each line states every item you need to check before ordering:
- Designation
- Quantity
- Price & currency
- Stock status
- Estimated lead time
- Quote validity
- Freight & tax terms
- Documents available
Distributor buyerHow should I read the quote validity?
How should I read the quote validity?
Prices and stock status apply until the validity date printed on the quote. After that date, ask for a re-confirmation before you place the order, because availability and pricing can change.
Distributor buyerPurchasing engineerWhich payment methods and commercial terms apply?
Which payment methods and commercial terms apply?
The ones stated on your quote. Check the specification, quantities, delivery details, payment method and commercial terms before ordering. The order is placed against that reviewed quote.
Maintenance supervisorDistributor buyerIs the lead time guaranteed?
Is the lead time guaranteed?
No. Each quote gives an estimated lead time based on current stock status, not a fixed number of days. Include your required date and destination so the estimate reflects your shutdown window.
Distributor buyerCan ball, roller and housed bearings go in one enquiry?
Can ball, roller and housed bearings go in one enquiry?
Yes. One enquiry can cover deep groove, angular contact, cylindrical roller, spherical roller, self-aligning and thrust bearings as well as bearing units, across several plants or positions. Browse the SKF bearing range to build your list.
