Product Description
NTN Original High Load 7813 33113X2 Tapered Roller Bearing
Tapered roller bearings are generally of separable design and have tapered cone and cup raceway between which tapered rollers are arranged. Their design makes tapered roller bearings particularly suitable for carrying combined (radial and axial) load.
According to dimensional standard difference, tapered roller bearings can be grouped into metric and inch size series.
The metric tapered roller bearings are designed according to the European International Standard ISO 492 and are divided into
subfamilies based on their outer diameter and height.
This typology is the standard kind, which allows them to be used in many applications, thanks to the combined load distribution
and high performance at optimum speeds.

FAQ1: Is NTN 33113X2 suitable for high-load machinery applications?
Yes, the NTN 33113X2 is very suitable for high-load machinery applications. Tapered roller bearings, by their very design, are engineered for this purpose. The conical shape of the rollers and raceways allows the bearing to effectively handle a combination of high radial loads (forces perpendicular to the shaft) and high axial loads (forces parallel to the shaft). This makes it ideal for heavy-duty environments found in truck axles, industrial gearboxes, and construction equipment.
FAQ2: How long does an NTN tapered roller bearing last under heavy load?
The lifespan of an NTN tapered roller bearing under heavy load is not a fixed value but is determined by its basic rating life and adjusted rating life.
1. Basic Rating Life (L 10 ): This is the number of revolutions that 90% of a large group of identical bearings will achieve or exceed before material fatigue occurs. This value is calculated based on the bearing’s dynamic load rating and the applied load.
2. Adjusted Rating Life: This calculation takes into account additional factors that affect the bearing’s life, such as lubrication quality, operating temperature, and contamination.
3. Key Factors: Even with a high-quality NTN bearing, the actual lifespan under heavy load can be shortened by inadequate lubrication, incorrect installation, excessive heat, and the presence of contaminants. However, under ideal conditions and within its specified load limits, an NTN tapered roller bearing is engineered to provide a long and reliable service life, often many years in a heavy-duty industrial application.
