German PTS bearings, PTS models, PTS prices

PTS bearings are roller bearings with cylindrical rollers. Relative to their diameter, the rollers are both thin and long. These rollers are called needle rollers. Despite having a small cross-section, the bearings still have high load-carrying capacity. Needle roller bearings are equipped with thin and long rollers (roller diameter D ≤ 5mm, L/D ≥ 2.5, where L is the roller length). Therefore, the radial structure is compact. When the inner diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest, making them particularly suitable for support structures with limited radial installation dimensions. Depending on the application, bearings without inner rings or needle roller and cage assemblies can be selected.
