German Dr TRETTER coupling Dr TRETTER model Dr TRETTER price
Dr TRETTER couplings are divided into two main categories: convex and concave. The convex type is further divided into three types: integral with skeleton, integral without skeleton, and radial slit. The inner side of the tire ring is bonded to the steel skeleton by vulcanization, and nuts are welded at the bolt holes on the skeleton. During assembly, bolts are used to connect the flanges of the two halves of the coupling. Torque is transmitted by the friction generated between the tire and the flange end faces when the bolts are tightened. The tire ring undergoes torsional shear deformation during operation, so tire couplings have high elasticity, a large ability to compensate for relative displacement between two shafts, and good damping.
German Dr. TRETTER bearings Dr. TRETTER models Dr. TRETTER prices
Dr. TRETTER roller bearings with cylindrical rollers, where the rollers are thin and long relative to their diameter. 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, L is the roller length), resulting in a compact radial structure. 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 space. Depending on the application, those without an inner ring can be selected.
