FAQ

Question? What does the ‘PP’ suffix in NATR5-PP-A signify?

The ‘PP’ designation indicates that the track roller is equipped with plastic axial plain washers and formed seal lips on both sides. These provide effective contact sealing against contamination and prevent lubricant leakage.

Question? What is the advantage of a crowned outer ring?

A crowned outer ring helps to reduce edge stresses if the track roller runs at an angle relative to the raceway. This prevents excessive wear and extends the operational life of both the roller and the track.

Question? Is this bearing pre-lubricated?

Yes, INA track rollers like the NATR5-PP-A are supplied filled with a high-quality lithium complex soap grease. They are generally considered lubricated for life under normal operating conditions, but relubrication requirements should be verified based on the specific application’s demands.
