NTN 7212 angular contact ball bearing

NTN 7212 belongs to angular contact ball bearing, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 7212 and any equivalents.

When a shaft has to carry radial and axial force at the same time, an angular contact ball bearing is often the right answer. The raceways sit offset from each other, so the balls meet them at an angle instead of straight on. That geometry gives the bearing more capacity for thrust than a deep groove ball bearing of the same size. Machine tool spindles, pumps, compressors and gearboxes are the usual homes for this design, where precision and rigidity matter. MR Industrial Accessories supplies the NTN line to maintenance and purchasing teams in the United States and Latin America.

Reading the part number tells you most of what you need. The first digits identify the series: 7000 covers single row bearings with a 15° or 25° contact angle, 7200 uses a wider angle, and 7300 wider still. Suffixes carry the rest. C means a 15° contact angle, AC means 25°, and B means 40°. You may also see P for a polyamide cage, G for a brass cage, or DB, DF and DT for paired arrangements. If any of these letters are unclear, send us the full number and we will confirm.

These bearings show up in metalworking, food processing, petrochemical plants and general process industries. Typical mountings include milling machine and CNC lathe spindles, centrifugal pumps, screw compressors, gearboxes and transmission equipment. Because the bearing takes axial load in one direction, it suits arrangements that need preload and stiffness. MR Industrial Accessories supports workshops, plants and maintenance departments across the United States and in several Latin American countries.

Selection comes down to a few variables: how large the loads are and which way they push, how fast the shaft turns, and what the surrounding environment looks like. Sealing options range from open, to shielded with ZZ, to sealed with LLB or LLU, depending on contamination levels and whether you need to hold lubricant in place. Internal clearance and preload deserve attention too, since a mounting set up with the wrong preload can run hot. The supports also have to line up accurately, as this bearing type does not tolerate misalignment well. Grease or oil both work as lubricants, chosen according to speed and temperature.

On interchangeability, an NTN angular contact bearing can replace units from SKF, FAG, NSK or Timken when the main dimensions and contact angle line up. Suffix conventions differ from one maker to the next, so check the complete part number and the technical data rather than the base number alone. A replacement should also match the original in load capacity and configuration. Our technical team can review the details with you before you commit to an equivalent.
