SKF RNA 4904 needle bearing without inner ring

Product detailed description

SKF RNA 4904 is a needle roller bearing without an inner ring, designed for applications requiring high load capacity and compact dimensions. This bearing is characterized by its cylindrical bore profile and is made of high-quality steel, which guarantees its durability and long service life. The dimensions of the bearing are as follows: inner diameter (d) is 25 mm, outer diameter (D) is 37 mm and width (B) is 17 mm.

The bearing is equipped with a steel cage, which ensures uniform distribution of the needles and minimizes friction, thereby increasing its efficiency. SKF RNA 4904 is seal-free, which means that it is suitable for applications where protection against external contaminants is not required or where external lubrication is provided.

The operating temperature of the bearing ranges from -20 °C to +100 °C, which allows it to be used in various industrial conditions. The bearing has a normal clearance, which is suitable for most standard applications where special adjustments for thermal expansion or other factors are not required.

SKF, as a renowned bearing manufacturer, guarantees high quality and reliability of its products, which makes RNA 4904 an ideal choice for various industrial applications where high load capacity and compact dimensions are required.
