8. FAQ

Q1: What does VZ seal stand for?
A1: VZ is double reinforced rubber contact seal, better dust-proof and anti-grease-leak performance than single metal shield ZZ, suitable for slightly dusty agricultural and vehicle environments.
Q2: Can this bearing replace original NSK 40TM18VZ?
A2: Yes, all bore, outer diameter and width sizes fully consistent, direct interchange without modifying housings or shafts.
Q3: What load can this bearing support?
A3: Mainly for radial load, also bears small axial force from both directions, suitable for medium-load tractor and auto auxiliary transmission shafts.
