Metallurgical forging machinery, large extrusion equipment, heavy-duty industrial reducers and mining heavy-load transmission devices sustain enormous unidirectional axial loads during operation, accompanied by impact vibration. Ordinary thrust bearings feature limited load capacity and cannot withstand continuous high-pressure loads for long. Rollers are prone to indentation and fragmentation, leading to rapid bearing failure and shutdown. Many heavy-duty transmission equipment have limited internal installation space. Bearings are required to achieve ultra-large axial load capacity within limited thickness dimensions, while conventional bearing structures hardly balance volume and load demands. Some forging and metallurgical working conditions involve high temperature and metal dust. Impurities easily invade rolling contact surfaces, destroy lubricating films, aggravate rolling element wear and shorten bearing service life.

Traditional flat thrust washers lack sufficient rigidity and deform easily under heavy loads, resulting in uneven load distribution, local stress concentration and abnormal loss of rolling elements. Heavy-duty equipment starts and stops frequently with large instantaneous impact loads. Insufficient bearing rigidity will cause continuous variation of operating clearance, declining transmission accuracy and violent vibration during equipment operation. The market demands thrust cylindrical roller bearings featuring high rigidity, ultra-large axial load capacity and excellent impact resistance to adapt to various heavy-duty transmission, forging and extrusion equipment and ensure stable continuous operation under heavy loads.

NMT Thrust Cylindrical Roller Bearings consist of shaft washers, housing washers, cylindrical rollers and cages, specially designed to bear unidirectional axial loads. The structure owns sufficient rigidity to withstand extremely large axial pressure. Rollers are manufactured with high-precision processing technology and feature high dimensional consistency for even load distribution, effectively lowering risks of local stress concentration. Shaft washers and housing washers undergo hardening quenching and precision grinding treatment with high contact surface hardness, excellent pressure and wear resistance to resist surface indentation caused by heavy-load impact. Cages restrict roller positions accurately to prevent roller offset and mutual friction and maintain stable operation.

The bearings adopt compact structure with streamlined axial dimensions, suitable for limited internal installation space of heavy-duty equipment. The full product line complies with standardized overall dimensions and delivers excellent interchangeability. Mainstream thrust bearings of the same type on the market can be replaced directly, and large-scale modification of box structures is unnecessary during equipment maintenance and renovation. High-temperature lubrication schemes are compatible to adapt to high-temperature working conditions in metallurgy and forging industries. Dust-proof protective components are optional to block metal dust from entering rolling zones and extend bearing service life. The bearings are widely applied to various heavy-duty transmission mechanisms bearing continuous heavy axial loads.
