81108 Thrust Ball Bearing | M / TN Types Available
The 81108 thrust ball bearing is a precision single-direction thrust ball bearing designed to withstand pure axial loads. With a compact structure, high rigidity and low-friction operation, it provides accurate axial positioning and stable performance for low to medium-speed industrial machinery. Available in 81108M and 81108TN cage types, this bearing delivers reliable and cost-effective support for various mechanical transmission systems.
81108 M / TN Type Differences
81108M: Built with a solid machined brass cage featuring high structural rigidity, excellent heat resistance and strong impact resistance. It maintains low wear and stable operation during long continuous running, making it ideal for heavy-load, high-temperature and harsh industrial working conditions.
81108TN: Adopts a lightweight nylon TN cage with low friction coefficient and quiet rotation performance. It offers great anti-fatigue ability and outstanding cost performance, perfectly suitable for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81108 thrust ball bearings adopt high-quality GCr15 high-carbon chromium bearing steel. After precise heat treatment, the raceways and steel balls obtain high hardness, superior wear resistance and stable fatigue resistance, ensuring long-term precise and stable operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81108 bearings feature excellent rust-proof, anti-oxidation and weak corrosion resistance. They adapt to humid, dusty and sanitary working scenarios, effectively avoiding premature bearing damage and extending service life.
Product Features
Stable single-direction pure axial load capacity. High-precision axial positioning with low running noise. Two cage structures meet different speed and load demands. High hardness and wear resistance prolong service life. Compact structure saves installation space with high cost performance.
Application Scenarios
81108 thrust ball bearings are widely applied in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81108M fits heavy-load and harsh working environments; 81108TN is suitable for medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
