Journal bearing is characterized by a certain gap being inside and outside of bearing. When the journal spins, the rotational speed of journal bearing increases with the axis with the help of the friction force of lubricating oil. However, the rotational speed of the journal bearing will not increase with that of journal after it has reached to a certain degree.

Technological requirements for journal bearing: A reliable work of journal bearing calls for a higher dimensional accuracy and surface roughness requirements. As journal bearing works with a certain rotational speed, its structure, compared with the axis, should have a better symmetry, enabling journal bearing to have a good balancing. A fine concentricity should be ensured when processing. Besides, oil scupper and oil hole should have a symmetrical and even distribution.

Tonglint can provide journal bearings including:

TO4B, TB25, TB31, KO3, TBP4, TB34, TD04, GT15, GT2255, TO4E, T3, T4, T3/T4, HX35, HX40, S100, S180, etc.

Tonglint can design, process and produce journal bearings in accordance with client’s drawing and sample.

As for clients requiring journal bearings, please specify their material and offer samples or drawings.
