81104 Thrust Ball Bearing | M / TN Types Available
The 81104 thrust ball bearing is a compact, high-precision single-direction thrust bearing designed to withstand pure axial loads. It features low friction, high rigidity and accurate axial positioning, delivering stable and quiet operation for low-speed and medium-speed mechanical systems. Available in 81104M and 81104TN types, this bearing is widely used for precision axial support in general industrial machinery.
81104 M / TN Type Differences
81104M: Equipped with a solid machined brass cage. It offers high structural rigidity, strong impact resistance and excellent stability under continuous operation. The brass cage features low wear and good thermal stability, ideal for conventional heavy-load and long-running industrial equipment.
81104TN: Adopts a lightweight nylon TN cage with flexible structural design. It provides lower friction coefficient, quieter operation and better anti-fatigue performance. With outstanding cost performance, it is more suitable for medium-speed, clean and stable working environments.
Material Introduction
Bearing Steel (GCr15): 81104 thrust ball bearings adopt standard GCr15 high-carbon chromium bearing steel. After precise quenching and tempering treatment, the raceway and steel balls achieve high hardness, excellent wear resistance and stable contact fatigue resistance, ensuring long-term precise operation under axial loads.
Stainless Steel (Optional): Custom stainless steel 81104 bearings feature reliable rust-proof and anti-oxidation performance. They adapt to humid, dusty and lightly corrosive environments, effectively avoiding precision failure and extending service life for special industrial scenarios.
Product Features
High-precision single-direction axial load capacity. Stable axial positioning and low operational noise. Two cage structures meet different speed and load demands. High hardness and wear resistance ensure long service life. Compact structure saves installation space with high cost performance.
Application Scenarios
81104 thrust ball bearings are commonly used in gearboxes, hydraulic equipment, small fans, textile machinery, printing machinery and general mechanical transmission systems. 81104M fits continuous heavy-load and harsh working conditions; 81104TN is perfect for medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary working environments.
