89312 Thrust Ball Bearing | M / TN Types Available
The 89312 thrust ball bearing is a heavy-duty single-direction thrust ball bearing built for high pure axial load conditions. With high structural rigidity, superior load capacity and stable low-friction operation, it ensures accurate axial positioning and reliable support for medium-speed heavy-duty industrial machinery. Available in 89312M and 89312TN cage types, this bearing delivers durable and cost-effective thrust support for heavy mechanical transmission systems.
89312 M / TN Type Differences
89312M: Features a solid machined brass cage with high rigidity, great heat resistance and strong impact resistance. It effectively resists deformation under heavy loads and supports long-term continuous operation, ideal for heavy-load, high-temperature and harsh industrial working environments.
89312TN: Adopts a lightweight reinforced nylon TN cage with low friction and quiet rotation. It offers stable anti-fatigue performance and high cost efficiency, perfectly suited for medium-speed, clean working conditions with heavy axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 89312 thrust ball bearings use premium GCr15 high-carbon chromium bearing steel. Professional heat treatment provides high hardness, excellent wear resistance and stable fatigue resistance for raceways and steel balls, guaranteeing long-term stable operation under continuous heavy axial loads.
Stainless Steel (Optional): Custom stainless steel 89312 bearings provide excellent rust-proof, anti-oxidation and weak corrosion resistance. They adapt well to humid, dusty and sanitary working scenarios, preventing premature bearing damage and extending service life.
Product Features
Strong single-direction heavy axial load capacity. High-precision axial positioning with low operating noise. Dual cage designs fit various heavy-duty working demands. High hardness and deformation resistance extend service life. Compact structure with outstanding cost performance.
Application Scenarios
89312 thrust ball bearings are widely applied in heavy-duty hydraulic equipment, industrial gearboxes, mining machinery, construction machinery and heavy mechanical transmissions. 89312M is suitable for heavy-load and harsh working environments; 89312TN fits medium-speed, low-noise and cost-sensitive heavy equipment. Stainless steel versions apply to humid and sanitary industrial scenarios.
