During operation of numerous vertical hydraulic equipment, lifting mechanisms, valve assemblies and tool fixtures, loads are mainly vertical axial pressure with low rotating speed. The core requirement is to reliably withstand axial thrust and limit vertical shaft play. Ordinary radial bearings have limited axial load capacity. Long-term exposure to axial pressure easily causes plastic raceway deformation, ball indentation and continuous clearance expansion, leading to positioning failure and lifting deviation. Some equipment requires bidirectional axial restriction, while single-direction thrust structures cannot handle pressure from both directions and result in operational shaking. In addition, diverse working environments allow moisture and fine dust to enter bearings, triggering corrosion and wear, shortening service life and impairing positioning accuracy.

Aiming at common pain points of low-speed axial positioning equipment, Japan NMT develops and optimizes universal thrust ball bearings. Based on planar axial raceway structure, the product range includes single-direction types for unidirectional axial loads and double-direction types capable of bearing thrust from both sides. Equipped with five core upgrades: high-purity bearing steel, mirror superfinished raceways, precisely sorted steel balls, low-friction cages and stabilized heat treatment. Compact in size for installation in limited spaces, the bearings bear axial pressure with clear force direction and evenly distribute contact stress. Suitable for intermittent low-speed rotation, static pressure bearing and axial positioning, they are widely used for various vertical hydraulic equipment, lifting components, valves and tool transmission mechanisms.

Core Product Advantages

1. Specialized axial load bearing for stable positioning: Dedicated thrust structure efficiently withstands axial thrust and controls axial shaft play, meeting precise limiting requirements of presses and valves and preventing axial offset.

2. Single-direction and double-direction versions available for different load directions: Single-direction types sustain pressure from one side; double-direction types resist thrust in both directions to satisfy equipment requiring bidirectional restriction and match various mechanical design schemes flexibly.

3. Compact structure saving installation space: Low overall thickness fits confined assembly spaces, convenient for both new machine design and equipment retrofitting with simple disassembly and assembly, lowering structural design difficulty.

4. Stable friction and excellent wear & rust resistance at low speed: Precisely machined inner and outer raceways paired with uniform-dimension balls ensure smooth low-speed rotation without jamming. Hardened and anti-rust treated materials resist mild moisture and dust to slow wear and corrosion.

5. Uniform load distribution resisting deformation under long static pressure: Optimized ball arrangement disperses axial pressure to avoid local indentation under sustained static load, retaining positioning accuracy over long periods and reducing frequent adjustment and maintenance.
