INA NKI 9/12-XL needle bearing

Product detailed description

INA NKI 9/12-XL is a needle roller bearing that is characterized by high quality and precision processing. This bearing is designed with a cylindrical bore and is made of steel, which guarantees its strength and wear resistance. With an inner diameter of 9 mm, an outer diameter of 19 mm and a width of 12 mm, this bearing is suitable for applications where compactness and high load capacity are required.

The bearing is single-row, which means that it contains one row of needles that are housed in a pressed steel cage. This design allows for effective load distribution and reduces friction between moving parts. The inner ring is part of the bearing, which simplifies its installation and increases overall stability.

The operating temperature range of the bearing is from -20 °C to +100 °C, which allows it to be used in various industrial conditions. The bearing has no seal, which means it is uncovered and requires regular maintenance and lubrication. Lubrication is provided via a circumferential groove with lubrication holes, which allows for easy and efficient replenishment of lubricant.

Normal radial clearance and running accuracy in class P0/PN (resp. ABEC 1) guarantee reliable and smooth operation of the bearing. With a weight of 0.016 kg, this bearing is lightweight, which contributes to reducing the overall weight of the mechanisms in which it is used. The manufacturer INA is known for its reliability and quality, which makes this bearing a suitable choice for various technical applications.
