89304 Thrust Ball Bearing | M / TN Types Available
The 89304 thrust ball bearing is a high-load single-direction thrust bearing designed for heavy pure axial load conditions. Featuring high rigidity, strong load capacity and stable low-friction operation, it delivers reliable axial positioning for medium-speed heavy-duty industrial machinery. Available in 89304M and 89304TN cage types, this bearing provides durable and cost-effective thrust support for heavy mechanical transmission systems.
89304 M / TN Type Differences
89304M: Equipped with a solid machined brass cage with ultra-high rigidity, excellent heat resistance and outstanding impact resistance. It resists deformation under heavy loads and maintains stable operation during long-cycle continuous work, ideal for heavy-load, high-temperature and harsh industrial working conditions.
89304TN: Adopts a lightweight reinforced nylon TN cage with low friction coefficient and quiet rotation performance. It features excellent anti-fatigue properties and high cost performance, perfectly suited for medium-speed, clean working environments with standard heavy axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 89304 thrust ball bearings adopt premium GCr15 high-carbon chromium bearing steel. Through precise heat treatment, the raceways and steel balls achieve high hardness, superior wear resistance and stable fatigue resistance, supporting long-term stable operation under continuous heavy axial loads.
Stainless Steel (Optional): Custom stainless steel 89304 bearings offer excellent rust-proof, anti-oxidation and weak corrosion resistance. They adapt perfectly to humid, dusty and sanitary working scenarios, effectively preventing premature bearing damage and extending service life.
Product Features
Excellent heavy-duty single-direction axial load capacity. High-precision axial positioning with low running noise. Two cage structures match different working conditions. High hardness and deformation resistance for long service life. Compact structure with high cost performance.
Application Scenarios
89304 thrust ball bearings are widely used in heavy-duty hydraulic equipment, industrial gearboxes, mining machinery, construction machinery and general heavy mechanical transmissions. 89304M is suitable for heavy-load and harsh working environments; 89304TN fits medium-speed, low-noise and cost-sensitive heavy equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
