Moderate — 2–4 hours
Description
This aftermarket part is rated as 'Better' and features an NTN USA 6206C3 bearing. It has the correct C3 internal clearance for heat and high-speed operation. The bearing utilizes a polymer cage, which differs from OEM metal cages, offering smooth, low-friction performance but with a potentially lower high-temperature margin.
