32205 Tapered Roller Bearing A High Load Easy Maintenance Core
Industrial Component
Model & Basic Parameters
The 32205 tapered roller bearing (corresponding to the old model
7505) features a single-row separable design, with key dimensions
as follows:
- Bore diameter (d):25mm
- Outer diameter (D):52mm
- Width (T):19.25mm
- Weight:Approx. 0.18kg
- Contact angle:20°~21.25°, capable of handling both radial and one-way axial
loads.
Core Performance & Technical Features
- High Load Capacity & Impact Resistance
- Basic dynamic load rating (Cr): 32.5kN (NACHI) to 44.5kN (SKF);
static load rating (C0r): 35kN (NACHI) to 46kN (FAG), suitable for
heavy-load conditions.
- Made of 51200 bearing steel or GCr15, with surface hardness
reaching HRC58-62 after quenching and low-temperature tempering,
ensuring wear and fatigue resistance.
- High Precision & Long Service Life
- Standard precision class (ABEC-1/P0), with a limiting speed of
10000~14500rpm (grease-lubricated), meeting medium-to-high speed
operation requirements.
- Separable structure (inner ring + roller assembly and outer ring
are independent), facilitating installation and debugging, and
reducing maintenance time.
- Flexible Adaptability & Environmental Compatibility
- Compatible with shaft diameter tolerances H7/k6 and bearing housing
bore tolerances J7, aligning with most industrial equipment
installation standards.
- Customizable stainless steel versions (e.g., 32205-B-XL) for
high-temperature, corrosive environments (e.g., steel plants,
chemical equipment).
Typical Application Scenarios
- Automotive & Agricultural Machinery
- Tractor wheel hubs, harvester transmission systems, withstanding
radial loads and axial impact from field vibrations.
- Truck drive shaft supports, ensuring stability during high-speed
driving.
- Industrial Equipment
- Reducers, injection molding machine spindles, handling periodic
high loads.
- High-temperature equipment such as spray dryers and kiln cars;
high-temperature models (e.g., 32205/S1) can withstand temperatures
above 300°C.
- New Energy Sector
- Wind turbine gearboxes, supporting axial loads and yaw moments to
ensure power generation efficiency.
Maintenance & Lubrication Recommendations
- Lubrication method: Prefer lithium-based grease (e.g., SKF LGMT2) with a filling
volume of 10%-15% of the bearing space; circulating oil lubrication
is suitable for high-speed or high-temperature scenarios.
- Sealing design: Standard open structure; optional labyrinth seals or flint seals
(model suffixes such as "-2RS") to prevent dust intrusion.
Certifications & Quality Assurance
- Compliant with ISO 355 international standards; some manufacturers
are certified to ISO 9001:2008 and TS 16949, ensuring consistency
in mass production.
- Compatible with mainstream brands (SKF, FAG, NACHI) and supports
cross-brand replacement (e.g., 32205-B, 7505E).
Selection & Customization Services
- Parameter customization: Adjustable bore tolerances (e.g., P5 precision), contact angles
(25°~30°), and surface coatings (e.g., phosphating).
- Special requirements: For high-temperature, corrosion-resistant, or high-cleanliness
scenarios (e.g., food machinery), stainless steel or fully sealed
versions are available.
Summary
The 32205 tapered roller bearing, with its high load capacity, easy
maintenance, and strong adaptability, serves as a core component in
industrial transmission. Its separable design and standardized
interfaces reduce maintenance costs, while a wide range of material
and sealing options further expand its application boundaries.
Whether in agricultural machinery field operations or precision
operation of new energy equipment, the 32205 bearing provides
reliable performance to support long-term equipment operation.
