SKF 21312 EK cylindrical roller bearing

Product detailed description

SKF 21312 EK is a spherical roller bearing that is characterized by the high quality and reliability typical of SKF products. This bearing has an inner diameter (d) of 60 mm, an outer diameter (D) of 130 mm and a width (B) of 31 mm. Its design is optimized for applications where combined loads, i.e. radial and axial loads in both directions, need to be handled.

The 21312 EK bearing is equipped with a tapered bore with a ratio of 1:12, which allows it to be mounted on tapered shafts or using an adapter sleeve. The internal radial clearance is normal, which is suitable for most standard applications. The bearing is made of high-quality steel, which guarantees long service life and reliability even in demanding operating conditions.

The outer ring of the bearing is equipped with lubrication grooves and holes, which allows for effective lubrication and thus extends the service life of the bearing. The bearing is seal-free, which means that it is suitable for applications where external lubrication is provided. The operating temperature range of the bearing is from -30 °C to +200 °C, which allows it to be used in a wide range of industrial applications.

The bearing cage is made of pressed steel, which contributes to its robustness and ability to withstand high loads. The bearing falls into the Explorer category, which means that it is optimized for higher performance and efficiency. The running accuracy is ensured by the PN dimensional accuracy and P5 operating accuracy, which guarantees smooth and quiet operation.

With a total weight of 2.05 kg, the 21312 EK bearing is suitable for various industrial applications where high reliability and long service life are required. It is ideal for use in heavy machinery, where high demands are placed on resistance to loads and temperature fluctuations.
