Barden 205H5D P1R SG-1 Precision Ball Bearing

Barden 205H5D P1R SG-1 Precision Ball Bearing is a single‑row deep‑groove bearing from Barden’s 205H family, built for high‑precision, high‑speed rotation. It accommodates a 25 mm bore, a 52 mm outer diameter, and a 15 mm width, with all dimensions provided in bearing steel to tight tolerances. The 205H designation identifies a precision variant in this size, while the P1R SG-1 suffix specifies the exact variant in Barden’s catalog. A reference speed of about 40,000 rpm indicates strong performance in spin‑heavy applications, and the deep‑groove geometry supports reliable radial operation and stable axial loading within typical service conditions. The compact 25x52x15 size makes it a common choice for precision machinery components, such as spindle modules or instrumentation assemblies, where consistent radial play and smooth rotation are essential. Designed for demanding environments, it delivers the rigidity, repeatability, and long‑term durability expected from Barden precision bearings.
