Belt tension will not have any effect on the wear of the bearings.

Belt tension affects the load on bearings, and that load drives wear. In a belt drive, the belt has a tight side and a slack side; the difference between their tensions creates torque but both sides push on the pulley's rim and transmit forces to the shaft bearings. Higher tension increases the radial load on the bearings and can cause shaft deflection or misalignment, which raises bearing contact stresses and accelerates wear. If the tension is too low, the belt may slip, causing fluctuating loads and extra heat, also contributing to wear. Because belt tension changes the loads and stresses that bearings experience, it does have an effect on bearing wear, so the statement is not correct.
