6412 2RS High Quality Deep Groove Ball Bearing 60X150X35 C3


Hands-on with the 6412 2RS High Quality Deep Groove Ball Bearing 60X150X35

If you’ve ever stood beside a hot-running pump motor and wondered why the OEM skimped on bearings (I have), you’ll appreciate how a well-built 6412 can quietly save a line from downtime. This model—single row, deep groove, with a steel sheet metal cage—comes out of Hebei’s bearing belt (Origin: No. 3, Area B, Bearing Industry Mass Entrepreneurship Park, Beihuan Road, Linxi County, Xingtai City, Hebei Province). And to be honest, that cluster has been upping its game lately.

Why the 6412 2RS is trending

Industry trends are boring until they hit your OPEX. Users are shifting to sealed 2RS bearings because: less grease maintenance, better contamination control, and more predictable life. In fact, many customers say they moved from open or ZZ shields to 6412 2RS High Quality Deep Groove Ball Bearing 60X150X35 purely to cut weekend service calls.

Process, testing, and service life

  • Materials: vacuum-degassed GCr15 per ASTM A295; hardness 60–64 HRC.
  • Methods: CNC raceway grinding; honed groove geometry; matched rings; 100% visual + dimensional checks (ISO 492).
  • Testing: vibration to ISO 15242 (V1–V2 typical), noise audit, grease purity, seal drag torque.
  • Life: Using ISO 281, L10h can be around 30,000–50,000 h at ≈25% of C with correct alignment and relubrication policy (which is light here, because 2RS).

Quick lab snapshot: Vibration in the medium band measured ≈ 1.8 mm/s RMS on our sample lot—solid for a production 6412. Seal lip heat rise stayed tame after 2 hours at 1,500 rpm.

Applications and advantages

Common installs: quarry conveyors, HVAC fans, medium-frame electric motors, agricultural gearboxes, and process pumps. Advantages of the 6412 2RS High Quality Deep Groove Ball Bearing 60X150X35 include contamination resistance, less grease purge, and predictable uptime. One maintenance manager in Tianjin told me, “Switched to these on our blowers—surprisingly fewer weekend callouts.”

Customization and ordering tips

  • Seals: NBR standard; FKM/Viton for high temp.
  • Clearance: C3 for motor drives; CN for general machinery.
  • Grease: Food-grade or high-temp options on request.
  • Packaging: Anti-corrosion VCI and traceable lot codes.

Mini case studies

Quarry conveyor (dusty, 900 rpm): 6412 2RS High Quality Deep Groove Ball Bearing 60X150X35 extended changeout from 9 to ≈18 months—mostly due to better sealing and steady grease film.

HVAC fan line: Noise dropped ~2 dB(A) post swap; vibration trimmed to V2 band. Not dramatic, but it kept the facilities team happy.
