81111 Thrust Ball Bearing | M / TN Types Available
The 81111 thrust ball bearing is a high-precision single-direction thrust bearing specially designed for pure axial loads. It features a compact structure, high rigidity and low-friction operation, providing accurate axial positioning and stable operation for low and medium-speed industrial machinery. Available in 81111M and 81111TN cage types, this bearing delivers reliable and cost-effective thrust support for various mechanical transmission systems.
81111 M / TN Type Differences
81111M: Equipped with a solid machined brass cage with high structural rigidity, superior heat resistance and strong impact resistance. It ensures low wear and steady performance during long-term continuous operation, ideal for heavy-load, high-temperature and harsh industrial working conditions.
81111TN: Adopts a lightweight nylon TN cage with low friction coefficient and quiet rotation. It offers excellent anti-fatigue performance and high cost performance, perfectly suited for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81111 thrust ball bearings adopt premium GCr15 high-carbon chromium bearing steel. After professional heat treatment, the steel balls and raceways achieve high hardness, excellent wear resistance and stable fatigue resistance, supporting long-term precise and stable operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81111 bearings possess outstanding rust-proof, anti-oxidation and weak anti-corrosion properties. They adapt well to humid, dusty and sanitary working scenarios, effectively preventing premature bearing failure and extending service life.
Product Features
Stable single-direction pure axial load capacity. High-precision axial positioning with low operating noise. Two cage structures meet diverse speed and load demands. Superior hardness and wear resistance extend service life. Compact structure saves installation space with high cost performance.
Application Scenarios
81111 thrust ball bearings are widely used in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81111M is suitable for heavy-load and harsh working environments; 81111TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
