Suffix explanation:

• CA: Solid machined brass cage with center guide ring, anti-shock & high temperature resistant
• C3: Enlarged internal clearance, avoids jamming from thermal expansion under heavy load & high speed
• W33: Outer ring full circle oil groove + 3 refuel holes for centralized online lubrication
  Full load data and CAD drawings available on request

1. Superior self-aligning function offsets shaft bending and housing installation offset, prevents abnormal wear and bearing seizure
2. Integral brass CA cage high rigidity, resistant to impact, fatigue and high temperature for long-hour continuous operation
3. C3 extra clearance eliminates thermal expansion interference, suitable for high-speed, high-temperature, heavy shock working conditions
4. W33 oil groove design supports uninterrupted centralized lubrication, extends overhaul cycle and reduces equipment downtime
5. Double-row symmetrical roller layout delivers ultra-high composite radial-axial load capacity
6. Standard ISO metric dimension fully interchangeable with global mainstream bearing brands
7. Custom high-temperature EP grease, OEM laser marking, P6/P5 precision grades available
