Applications and selection notes
Angular contact ball bearings carry combined radial and axial load in one dominant direction. The contact angle between the raceway and the ball means a radial load always induces an internal axial component, so single bearings are mounted either in pairs or against a second bearing that takes the opposing axial force. Typical service: pump spindles, machine-tool spindles, compressors and high-speed motor heads where axial stiffness matters.
The 7200-series “B” execution in this page’s designation denotes the standard 40° contact angle. Where axial capacity in one direction is the dominant requirement, this is the usual series choice; duplex pairing arrangements (back-to-back, face-to-face or tandem) extend the capacity or stiffness in a controlled way.
How to read the specification table
The specification table’s load ratings and limiting speeds are catalog values for the designation, established for the manufacturer’s execution. In practice the working capacity of an angular-contact position is set by the pairing arrangement and preload, which the catalog numbers of a single bearing do not express — size the position as an arrangement, not as a single bearing.
Precision class and internal fit decisions matter more for this type than for deep groove bearings, because the running accuracy of the spindle depends on them. If your application calls for a paired set or a precision class above the standard execution, state it in the RFQ so the offer matches the arrangement you need.

7214B — buying questions
What does the designation 7214B mean?
7214B is a standard boundary-dimension designation: the dimension series fixes the outside diameter and width proportions, and the bore code fixes the bore diameter — 70 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 7214B enough for my application?
The table lists Cr = 86.4 kN and a catalog limiting speed of 3600 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 7214B?
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 7214B, 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 7214B 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.
