Tapper Roller Bearing 32205 High Load Easy Maintenance Core Industrial Component

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

1. 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.
2. 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.
3. 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

1. 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.
2. 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.
3. 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.
