INA RPNA 45/62 needle roller bearing without inner ring

Product detailed description

INA RPNA 45/62 is a needle roller bearing without an inner ring, designed for applications requiring the ability to compensate for misalignment or shaft bending. This bearing is manufactured by the renowned manufacturer INA, part of the Schaeffler Group, and is known for its high quality and reliability.

The bearing has an outer diameter (D) of 62 mm, an inner diameter (d) of 45 mm and a width (B) of 20 mm. Its design without an inner ring allows direct mounting on the shaft, which is advantageous in cases where it is necessary to minimize the dimensions and weight of the overall arrangement. The bore profile is cylindrical, which simplifies installation and increases the versatility of use.

The bearing is equipped with a pressed steel cage, which ensures optimal guidance of the needle rollers and contributes to the overall robustness and resistance to mechanical stress. The maximum operating temperature of the bearing is +100 °C, while the minimum temperature is -20 °C, which allows it to be used in a wide range of temperature conditions.

The running accuracy of the bearing is in the P0/PN class, which corresponds to the ABEC 1 standard, and provides sufficient accuracy for most industrial applications. The bearing weighs 0.176 kg, which is advantageous for applications where weight reduction is important.

This bearing is ideal for use in various industrial sectors, including machine and equipment manufacturing, where misalignment compensation capability and high reliability are required while maintaining compact dimensions.
