81105 Thrust Ball Bearing | M / TN Types Available
The 81105 thrust ball bearing is a high-precision single-direction thrust ball bearing engineered for pure axial load support. With compact structure, high rigidity and low-friction operation, it delivers stable axial positioning for low to medium-speed mechanical systems. Offered in 81105M and 81105TN cage types, this bearing is a reliable solution for general industrial precision transmission equipment.
81105 M / TN Type Differences
81105M: Features a solid machined brass cage with high structural rigidity and superior heat resistance. It boasts strong impact resistance and ultra-low wear during long-term continuous operation, perfectly suited for heavy-load, high-temperature and harsh industrial working conditions.
81105TN: Equipped with a lightweight nylon TN cage. It provides a lower friction coefficient, quieter rotation and excellent fatigue resistance. With great cost performance, this model is ideal for medium-speed, clean and stable operating environments with standard load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81105 thrust ball bearings adopt premium GCr15 high-carbon chromium bearing steel. Through professional quenching and tempering heat treatment, the raceways and steel balls gain high hardness, outstanding wear resistance and stable fatigue resistance, maintaining long-term precise operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81105 bearings deliver excellent rust-proof, anti-oxidation and weak corrosion resistance. They effectively adapt to humid, dusty and sanitary working environments, preventing premature bearing failure and extending service life.
Product Features
Professional single-direction pure axial load bearing capacity. Accurate axial positioning with low operating noise. Two cage designs meet diverse speed and load demands. High hardness and wear resistance ensure long service life. Compact and space-saving structure with high cost performance.
Application Scenarios
81105 thrust ball bearings are widely used in hydraulic machinery, gearboxes, industrial fans, textile equipment, printing machinery and general transmission systems. 81105M is applicable for heavy-load and harsh working scenarios; 81105TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions are suitable for humid and sanitary industrial environments.
