Então Nick matou a charada. Land é a pista, a superfície interna da carcaça do mancal de encosto. Portanto a resposta correta (a ser atribuída ao Nick) é: Os especialistas em mancais de encosto de pista interna cônica"

is the BEARING surface of the bearing housing.
Tapered-land thrust bearings find use in mid to large-sized high-speed machines such as turbines, compressors, and pumps. In most designs, a flat land extends an additional 10 to 20% of the circumferential breadth B at the trailing edge of each segment. This extension can boost load capacity 10 to 15% and reduce wear during starts, stops, and at low speeds. Gradual wear increases this flat portion to about 30 to 50% of total area, which helps maintain load capacity. In many turbine and compressor applications, individual segments are square (radial length L = B) and have a circumferential taper of about 0.003B0.5.

Tapered-land bearings are sensitive to load, speed, and lubricant viscosity, and therefore are commonly designed to match operating conditions of specific, constant-speed machines.

Martha, no momento não posso pesquisar, mas posso adiantar que thrust bearing é ROLAMENTO DE ENCOSTO (100% certeza). Tapered significa que né um rolamento de roletes cônicos. Você só precisa descobrir o que é o LAND nessa frase. Sem o land, seria "os especialistas em rolamento de encosto de roletes conicos."

Cheguei a: 'especialistas em rolamento cônico com pressão/empuxo terrestre. Confesso não estar seguro. :-)
