Applications and selection notes
Spherical thrust roller bearings of this series serve general industrial positions where their geometry — high radial capacity in a compact section — matches the load requirement.
How to read the specification table
Read the specification table as designation-bound catalog values; confirm execution, clearance and speed suitability against your application before ordering.

29426R — buying questions
What does the designation 29426R mean?
29426R is a standard boundary-dimension designation: the dimension series fixes the outside diameter and width proportions, and the bore code fixes the bore diameter — 130 mm for this bearing. Two bearings carrying the same designation from conforming manufacturers are dimensionally interchangeable; execution (seals, clearance class, cage) is the part that can differ, so state the execution you need when you request a quotation.
Are the catalog load rating and speed of 29426R enough for my application?
The table lists Cr = 1490 kN and a catalog limiting speed of 1250 min-1. The load rating is the starting point of a life calculation, and the limiting speed is a catalog value for the manufacturer’s execution — seals, fits, temperature and lubrication all reduce the usable speed in a real assembly. Send the application conditions with your inquiry and we confirm suitability before quoting; do not size from the catalog speed alone.
What information do you need to quote 29426R?
Four things, in one message: the designation (and execution — seals, clearance class, precision class, if not standard), the quantity, the destination country, and any documents you require. Application conditions such as speed, load direction and temperature are welcome and let us verify the execution instead of assuming it. Quotation, lead time and the exact document set come back in writing.
Ordering & documentation
Documents
Standard export documentation — commercial invoice, packing list and certificate of origin — accompanies every shipment. The exact document set for your order, and any material or inspection paperwork you require alongside it, is confirmed in writing at quotation before the order is placed.
Quotation
To quote 29426R, send: the designation and required execution, quantity, destination country, and any required documents. Adding the application conditions (speed, load direction, temperature, fit) lets us confirm the execution and clearance class instead of quoting blind.
Sample & supply
Sample quantities of standard-designation bearings such as 29426R are available for evaluation before a bulk order. Bulk supply runs through own production plus a qualified outsourcing network, so catalog items are not capped by own-factory capacity; the confirmed lead time is stated in the quotation.
Current confirmed lead-time practice: 15-30 business days for bulk standard bearings; 5-10 for samples. Standard quality system: ISO 9001.
Storage & shipping
Bearings are packed moisture-protected for export and should be stored flat, in unopened original packaging, in a dry indoor area away from temperature swings. Do not unwrap or rotate bearings before mounting; rotate only by the ring being pressed, never through the rolling elements.
