8. FAQ

1. Q1: Difference between open, ZZ and 2RS versions of 19BSW05A?
   A1: Open type installed inside steering column with built-in circulating grease; ZZ metal shield for semi-sealed internal assembly; 2RS double rubber seal for exposed external shafts, dustproof and waterproof, pre-filled long-life grease.
2. Q2: Can 19BSW05A replace original NSK bearing directly?
   A2: Yes, all mounting dimensions and internal structure fully consistent, compatible with corresponding OE spare parts, no modification to steering components needed during assembly.
3. Q3: Suitable lubrication mode?
   A3: Open version matches long-life low-friction steering grease for maintenance-free use; sealed models are pre-filled with anti-wear grease at factory.
