PRODUCT DETAILS
The GRAE25NPPB adopts a deep groove raceway structure and is equipped with single-row steel ball rolling elements. It can not only stably bear large radial loads but also handle certain axial forces, ensuring smooth operation with low friction. The design with an eccentric sleeve and a sealing device can not only effectively prevent dust and impurities from entering, lock the lubricating grease to extend its service life, but also has a self-centering performance, which can flexibly compensate for the installation error and deformation of the shaft.
The inner diameter of the bearing is 25mm and the outer diameter is 52mm. It is suitable for various bearing housings such as PASE25-GG. The material is made of high-carbon chromium bearing steel (GCr15) and F1 carbon steel cage, which combines high strength and wear resistance. It is applicable to fields such as machine tools, textiles, and mining machinery, and is a reliable choice for ensuring the efficient and stable operation of equipment.
