Questions about ordering this bearing

What information confirms the correct SKF motor bearing?+

The full designation with every suffix: seal or shield type, clearance class and any special execution. Add the motor or machine model. If the marking is worn, send a clear photo and tell us which details still need checking.

How should I list the two bearing positions on a motor?+

List the drive-end (DE) and non-drive-end (NDE) bearings on separate lines, each with its own designation and quantity. Motors often use a different bearing at each end, and mixing them up leads to wrong quantities or bearings fitted in the wrong place.

What does the written quote include?+

Designation, quantity, price and currency, stock status, estimated lead time, quote validity and the freight and tax terms that apply. It also states which product documents can be supplied with the order.
