81114 Thrust Ball Bearing | M / TN Types Available
The 81114 thrust ball bearing is a precision single-direction thrust ball bearing engineered for pure axial load support. Featuring high rigidity, compact structure and low-friction operation, it delivers accurate axial positioning and stable performance for low to medium-speed industrial machinery. Available in 81114M and 81114TN cage types, this bearing offers reliable, cost-effective thrust support for diverse mechanical transmission systems.
81114 M / TN Type Differences
81114M: Features a solid machined brass cage with high structural rigidity, superior heat resistance and strong impact tolerance. It operates steadily with minimal wear during long-cycle continuous running, making it ideal for heavy-load, high-temperature and harsh industrial working conditions.
81114TN: Adopts a lightweight nylon TN cage with a low friction coefficient and quiet rotation performance. It provides excellent anti-fatigue properties and outstanding cost efficiency, perfectly suited for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81114 thrust ball bearings are manufactured from premium GCr15 high-carbon chromium bearing steel. After strict professional heat treatment, the steel balls and raceways gain high hardness, exceptional wear resistance and stable fatigue resistance, ensuring long-term precise and stable operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81114 bearings deliver excellent rust-proof, anti-oxidation and weak corrosion resistance. They adapt seamlessly to humid, dusty and sanitary working scenarios, effectively avoiding premature bearing failure and extending overall service life.
Product Features
Stable single-direction pure axial load capacity. High-precision axial positioning with low operational noise. Two cage designs accommodate different speed and load demands. Superior hardness and wear resistance prolong service life. Compact space-saving structure with excellent cost performance.
Application Scenarios
81114 thrust ball bearings are widely applied in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81114M is suitable for heavy-load and harsh working environments; 81114TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
