Applications and selection notes
Deep groove ball bearings are the default radial bearing for electric motors, fans, pumps, gearboxes, agricultural machinery and general industrial equipment. The single-row design carries radial load and a limited axial load in both directions, needs no adjustment after mounting, and runs at higher speeds than most alternative types of the same size.
In the sealed (2RS) and shielded (ZZ) executions, the bearing is lubricated for life and maintenance-free under normal operating conditions, which is why motor and appliance manufacturers standardise on them. In the open execution, the bearing is lubricated from the housing or shaft — the usual choice when the surrounding assembly provides filtration, re-lubrication or oil-bath lubrication.
How to read the specification table
Read the specification table against three limits. Boundary dimensions (bore, outside diameter, width) decide whether the bearing fits the shaft and housing — these are standardised designation-bound values and interchangeable across conforming manufacturers. Load ratings (Cr, C0r) describe when the bearing survives: Cr governs life under rotating load, C0r governs the static limit when the bearing stands still under load or makes slow oscillations.
Limiting speeds are catalog values established for the manufacturer’s execution, clearance and lubrication; they are not an operating recommendation for your application. Sealed and shielded executions, heavy fits, elevated temperature or misalignment all reduce the usable speed. Confirm the speed and clearance choice against your actual conditions before ordering — the internal-clearance class in particular should follow fit, temperature and speed, not a default.

6212 — buying questions
What does the designation 6212 mean?
6212 is a standard boundary-dimension designation: the dimension series fixes the outside diameter and width proportions, and the bore code fixes the bore diameter — 60 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 6212 enough for my application?
The table lists Cr = 65.6 kN and a catalog limiting speed of 5700 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 6212?
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 6212, 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 6212 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.
