Description
Basic Parameters
The 32205 tapered roller bearing is a precision-engineered component designed to handle combined radial and axial loads in various industrial and automotive applications. It features a bore diameter of 25 mm, an outside diameter of 52 mm, and a total width of 19.25 mm235. The bearing incorporates a contact angle of 21.25°, optimizing its capacity to manage both radial forces and unidirectional axial thrust while maintaining low friction during operation58. Constructed with high-quality SAE-52100 chrome steel for the inner and outer rings, it ensures durability and resistance to wear24. The separable design includes a stamped steel cage that securely retains 16 conical rollers, facilitating smooth rotation and efficient load distribution158.
In terms of load ratings, the bearing has a basic dynamic radial load capacity of 50.4 kN and a static radial load rating of 45.5 kN under ISO standards, making it suitable for heavy-duty applications510. It operates with a reference speed of 11,000 rpm and a limiting speed of 13,000 rpm when lubricated with oil, balancing performance and longevity510. This bearing is commonly used in automotive transmissions, industrial gearboxes, and machinery requiring robust axial guidance and high radial load support2412. Its interchangeable cone (inner ring) and cup (outer ring) design simplifies installation and maintenance, while the crowned raceway profiles reduce stress concentration and enhance misalignment tolerance5612.



Product Application
The 32205 tapered roller bearing, engineered with a robust design and versatile load-carrying capabilities, finds extensive use across diverse industries and mechanical systems. Its ability to handle combined radial and axial loads, coupled with high precision and durability, makes it an ideal choice for applications requiring reliable motion control and structural support.
In automotive systems, the 32205 bearing is critical for power transmission and wheel support:
- Transmissions & Differentials: Installed in manual/automated gearboxes, it manages the radial forces from gear meshing and the axial thrust from torque variations, ensuring smooth gear shifting and reduced noise. Its 21.25° contact angle optimizes load distribution during acceleration or deceleration.
- Wheel Hub Assemblies: Used in light trucks and commercial vehicles, the bearing supports the dynamic loads from road vibrations and cornering forces while accommodating slight misalignments caused by suspension movements. The separable cone (inner ring) and cup (outer ring) design simplifies maintenance during wheel servicing.
- Steering Systems: Integrates into steering knuckles to handle axial loads from steering torque and radial loads from vehicle weight, enhancing steering responsiveness and safety.
For heavy-duty industrial applications, the 32205 bearing excels in harsh environments:
- Gearboxes & Pumps: In industrial gear reducers and centrifugal pumps, it withstands high radial loads from gear meshing or impeller rotation, paired with axial loads from hydraulic pressure. The SAE-52100 chrome steel construction resists wear and corrosion, extending service life in dusty or wet conditions.
- Conveyor Systems: Used in roller conveyors and material handling equipment, the bearing supports the weight of transported goods and absorbs shock loads from start-stop operations. The stamped steel cage ensures stable roller alignment, minimizing friction and energy loss.
- Electric Motors & Generators: Mounted in motor shafts, it handles radial loads from rotor weight and axial loads from magnetic forces, enabling high-speed operation within the bearing’s 13,000 rpm limiting speed (oil-lubricated).
In farming equipment subjected to dirt, moisture, and variable loads:
- Tractor Axles & PTO Systems: Supports the heavy radial loads from agricultural implements (e.g., plows, harvesters) and axial loads from power take-off (PTO) torque, maintaining performance in muddy or uneven terrains. The crowned raceway profiles reduce stress concentration caused by misalignments from soil vibrations.
- Combine Harvesters: Installed in header drives and grain augers, the bearing resists contamination from crop debris through proper sealing (when paired with external seals), ensuring reliable operation during harvest seasons.
For machinery enduring extreme loads and harsh conditions:
- Excavators & Loaders: Used in swing drives and boom joints, it handles the high radial loads from bucket forces and axial loads from rotational movements, delivering stability in heavy-duty digging or lifting tasks.
- Mining Conveyors & Crushers: In ore processing equipment, the bearing withstands impact loads from rocky materials and high-temperature environments, thanks to its heat-treated steel components and efficient lubrication design.
In niche high-precision setups:
- Aircraft Ground Support Equipment: Used in landing gear test rigs or tow tractors, the bearing provides precise load support for repetitive motion cycles, meeting stringent aerospace reliability standards.
- Military Vehicles: Integrates into armored vehicle transmissions, enduring shock loads from rough terrain and delivering consistent performance under high-duty cycles.
