The NTN 4T-399A/394A is a high-quality, genuine NTN single row tapered roller bearing designed to efficiently accommodate both radial and axial loads. This precision-engineered bearing features a separable design, allowing for separate mounting of the cone (inner ring with rollers and cage) and cup (outer ring). Its robust construction ensures reliable performance and extended service life in demanding industrial and agricultural applications. The bearing's design provides a high axial load carrying capacity, which is dependent on its contact angle.
