EnglishThe 51104 is a high-speed, single-direction plane thrust ball bearing measuring 20 mm (ID) × 35 mm (OD) × 10 mm (Width). Designed as a separable 3-piece assembly to handle high axial (vertical) loads, it is an essential component for agricultural equipment, turntables, and gear assemblies. We supply the complete 51100 series (including 51101, 51102, 51103, and 51105) to B2B buyers across various industries. Available in precision grades up to P2, with custom sealing options (Open, ZZ, or 2RS) to match your specific environmental needs.

The 51100 Series Thrust Ball Bearing is engineered to accommodate axial loads in one direction only; it must not be subjected to any radial load. The 51104 model is a separable 3-piece unit consisting of a shaft washer (tight fit), a housing washer (loose fit), and a ball-and-cage thrust assembly. This separable design allows for independent mounting of the washers and the rolling elements, significantly simplifying the installation and maintenance processes in complex machinery.
Please cross-reference the dimensions below to ensure proper fitment on your vertical shaft or gear assemblies.

While standard thrust bearings are often "Open," we offer sealing options based on your operating environment:
Open: No seals or shields. Ideal for clean, closed gearboxes where the bearing is continuously lubricated by an oil bath.
ZZ (Metal Shields): Features non-contact steel dust covers. Provides protection against larger debris while maintaining virtually zero friction, allowing for the highest rotational speeds and reducing heat generation.
2RS (Rubber Seals): Features contact rubber seals. Provides a "sealed-for-life" barrier against fine dust, dirt, and moisture, making it perfect for harsh, outdoor agricultural environments where contamination risk is high.
The 51104 thrust bearing is highly versatile and heavily utilized across a wide spectrum of commercial and industrial sectors:
Agricultural machinery and farms (harvesters, tractors).
Manufacturing plants and machinery repair shops.
Food & beverage factories, restaurants, and retail food shops.
Building material shops, construction works, and energy/mining sectors.
We are dedicated to providing seamless supply chain solutions for global distributors and OEMs. Whether you require standard P0 tolerance for basic machinery or ultra-high precision P2 for specialized equipment, we can fulfill your exact specifications.
