NTN 4T-30205 tapered roller bearing

Product detailed description

NTN 4T-30205 is a tapered roller bearing that is characterized by high quality and manufacturing precision, typical of the Japanese manufacturer NTN. This bearing is designed for applications where it is necessary to transmit combined loads, i.e. radial and axial forces.

The bearing has an inner diameter (d) of 25 mm, an outer diameter (D) of 52 mm and an overall width (T) of 16.25 mm. The width of the outer ring (B) is 15 mm and the width of the inner ring (C) is 13 mm. These dimensions are optimized for effective load distribution and long bearing life.

Tapered roller bearings, such as this model, are characterized by their conical roller profile, which allows for effective transmission of combined loads. The hole profile is cylindrical, which simplifies mounting on the shaft. The bearing material is high-quality steel, which ensures high wear resistance and long service life even in difficult operating conditions.

The bearing is designed for operation in a temperature range from -30 °C to +120 °C, which allows its use in various industrial applications. The steel cage ensures roller stability and minimizes friction. The bearing is supplied without a seal, which means that it is suitable for applications where protection against contamination is not required or where an external seal is provided.

This bearing model is ideal for use in the automotive industry, in the manufacture of machinery and equipment, where high precision and reliability are required. The 4T-30205 marking indicates a specific series and size within the NTN product portfolio, which makes it easier to identify and select the right bearing for a specific application.
