Product Overview: The 32218 Tapered Roller Bearing
The 32218 Tapered Roller Bearing is a robust and essential component designed to handle heavy combined radial and axial loads. With key dimensions of 90mm bore diameter, 160mm outer diameter, and 42.5mm width, this bearing is part of our extensive 32200 Series within the broader Tapered Roller Bearings collection. Its unique design, featuring tapered inner and outer ring raceways with tapered rollers in between, makes it ideal for applications that must support both thrust and radial forces simultaneously. The single-row construction provides excellent load-carrying capacity in a compact space.
As a leading supplier of industrial and mechanical parts, we ensure our 32218 bearings are manufactured to precise industry standards, offering superior performance and durability. A key feature of this bearing type is its separability; the inner ring with the roller and cage assembly (cone) can be mounted separately from the outer ring (cup), simplifying installation, inspection, and maintenance procedures.
Key Features of the 32218 Bearing
- Combined Load Capacity: Expertly designed to accommodate high radial and axial (thrust) loads in one direction.
- Separable Design: The cone (inner ring, rollers, cage) and cup (outer ring) are separable, which facilitates easy mounting and dismounting.
- High Rigidity: Provides a rigid bearing application, crucial for machinery requiring precision and stability under load.
- Low Friction Operation: The logarithmic contact profile between rollers and raceways minimizes stress peaks and reduces friction, leading to lower operating temperatures and longer service life.
- Durable Construction: Manufactured from high-quality, case-hardened bearing steel for exceptional strength and resistance to wear and fatigue.
- Precise Roller Guidance: The flange on the inner ring guides the rollers accurately, ensuring stable performance even under heavy loads.
Common Applications of 32218 Bearings
- Automotive Transmissions & Drivetrains: Widely used in gearboxes, differentials, and axle assemblies where combined loads are prevalent.
- Vehicle Wheel Hubs: A standard choice for wheel bearings in cars, trucks, and trailers due to their ability to handle dynamic loads.
- Agricultural Machinery: Found in tractors, harvesters, and other heavy-duty farm equipment that operates in demanding conditions.
- Industrial Gearboxes: Provides reliable support for gears and shafts in various industrial reduction units and power transmission systems.
- Construction and Mining Equipment: Used in heavy machinery like cranes, excavators, and conveyor systems that require robust bearing solutions.
- Rolling Mills: Essential for supporting the rollers in steel and paper mills, withstanding extreme pressures and temperatures.
- Pumps and Compressors: Ensures the stability and longevity of rotating shafts in industrial fluid machinery.
