Vertical lathes, heavy pressure machinery, large extrusion equipment and large valve transmission mechanisms continuously bear significant bidirectional axial loads during operation. Ordinary single-direction thrust bearings only withstand unidirectional axial force and cannot balance alternating axial loads. Low-strength cages on simple thrust structures tend to deform under sustained heavy loads, causing deviation of ball tracks, motion jamming, abnormal vibration and accelerated wear, drastically shortening service life. Many heavy equipment operates continuously under low speed and heavy pressure with fluctuating loads. Poor raceway precision leads to stress concentration, local pitting corrosion and machine breakdown, resulting in high maintenance costs.

Disassembly and maintenance of heavy industrial equipment are complicated. Manufacturers demand transmission components with stable long-term load capacity to reduce service frequency. Dust and coolant oil in partial working conditions penetrate raceways and accelerate surface abrasion. Machinery manufacturers need double-direction thrust ball bearings with robust structure and strong bidirectional axial load capacity to balance alternating axial force, guarantee stable long-term operation and cut maintenance expenses.

NMT Double Direction Thrust Ball Bearings adopt symmetrical double raceway structure to withstand axial loads from two directions, ideal for heavy transmission scenarios with alternating axial force. Forged and heat-treated shaft washers and housing washers feature outstanding compression resistance. Superfinished raceways realize even stress distribution and avoid stress concentration and pitting risk under heavy loads. High-strength solid cages separate balls accurately and stabilize movement paths. Deformation is unlikely under heavy loads to prevent ball collision and guarantee smooth rotation. Rich specifications meet diverse installation dimension demands with simple assembly suitable for vertical heavy machinery. Carefully selected high-purity raw materials deliver excellent anti-fatigue performance for long-term low-speed heavy-load operation. Optional protective washers block foreign substance intrusion and extend service life.

Complete specifications cover mainstream industrial requirements. Widely used in vertical lathes, vertical grinders, hydraulic presses, extrusion equipment, large pipeline valves and heavy rotary worktables. Standard dimensions support direct replacement during equipment upgrading.
