81112 Thrust Ball Bearing | M / TN Types Available
The 81112 thrust ball bearing is a precision single-direction thrust bearing engineered for pure axial load bearing. Featuring high rigidity, low friction and compact structure, it provides accurate axial positioning and stable operation for low and medium-speed mechanical equipment. Offered in 81112M and 81112TN models, this bearing is a durable and cost-effective solution for general industrial transmission systems.
81112 M / TN Type Differences
81112M: Designed with a solid machined brass cage, featuring high rigidity, excellent heat resistance and strong impact resistance. It runs stably with low wear during long-term continuous operation, perfectly suitable for heavy-load, high-temperature and harsh industrial working conditions.
81112TN: Equipped with a lightweight nylon TN cage with low friction coefficient and quiet rotation performance. It delivers reliable anti-fatigue ability and great cost performance, ideal for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81112 thrust ball bearings adopt high-quality GCr15 high-carbon chromium bearing steel. With professional heat treatment, the steel balls and raceways gain high hardness, outstanding wear resistance and stable fatigue resistance, ensuring long-term precise operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81112 bearings have excellent rust-proof, anti-oxidation and weak corrosion resistance. They adapt to humid, dusty and sanitary working scenarios, effectively avoiding premature bearing failure and extending service life.
Product Features
Excellent single-direction pure axial load capacity. 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 and space-saving structure with high cost performance.
Application Scenarios
81112 thrust ball bearings are widely applied in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81112M suits heavy-load and harsh working environments; 81112TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions are applicable for humid and sanitary industrial conditions.
