The P-140.50.400 half shaft is a stub axle for trailed equipment produced by S-TECH LLC (S-Teh), a Russian manufacturer that specialises in the development, production and sale of half shafts and hubs for trailers. The part belongs to the company's P-140 family: a 50 mm shaft in the 94 x 140 size, carrying the wheel on five M16x1.5 studs.
The rated load is 1,200 kg per wheel at 25 km/h and 950 kg at 45 km/h, with a unit weight of 12.58 kg, which makes it a practical running-gear component for tractor trailers and similar agricultural transport. S-Teh machines every part on modern CNC equipment and fits Russian-made bearings manufactured to GOST with increased load capacity, and each half shaft passes multi-stage quality inspection before it is shipped.
Thanks to the quality of the materials used, the manufacturer positions its half shafts as a longer-lasting alternative to typical replacement parts. The company also accepts individual orders and can manufacture axle components to a customer's own drawings, so the P-140.50.400 can be supplied both as a standard catalogue item and as part of a tailored running-gear solution for trailer builders and repair operations.
