Description

Basic Parameters

Prefix “3”: Indicates the bearing type is a tapered roller bearing (standard prefix for this category in bearing coding systems).

“29”: Represents the size series, which defines the bearing’s aspect ratio (e.g., width and diameter proportions). For tapered roller bearings, different series correspond to specific design configurations (e.g., single-row, double-row).

“22”: Denotes the inner diameter through the standard coding rule.

Features and Performance

Combined Load Capacity

Designed to withstand both radial and axial loads simultaneously (unlike unidirectional thrust bearings). Axial load capacity is directionally dependent (single-row design resists axial loads in one direction; double-row designs can handle bidirectional loads, but 32922 is typically single-row).High radial rigidity makes it suitable for applications with heavy radial loads, such as gearboxes or axle systems.

Tapered Geometry

The tapered shape of the rollers and raceways allows for line contact between rolling elements and races, distributing loads over a larger area compared to point contact in ball bearings. This enhances load-carrying capacity and resistance to deformation under heavy loads.

Adjustable Clearance

Clearance (axial and radial) can be adjusted during installation by controlling the relative position of the inner and outer rings. This is critical for optimizing performance in precision applications (e.g., machine tool spindles).

Detachable Structure

The inner ring (cone) and outer ring (cup) are separable, simplifying installation and maintenance. This feature is particularly useful in assemblies where one component must be mounted before the other (e.g., shafts with shoulders).

High-Speed Limitations

Compared to ball bearings, tapered roller bearings have lower maximum rotational speeds due to increased sliding friction between rollers and raceways. Suitable for moderate-speed applications (e.g., automotive differentials).

Self-Alignment Limitations

Not self-aligning; requires precise shaft and housing alignment to avoid edge loading, which can cause premature wear or failure.

Materials and Construction

Core components use AISI 52100 high-carbon chromium bearing steel (equivalent to GCr15), heat-treated to 60-62 HRC for high wear/fatigue resistance and dimensional stability under long-term harsh conditions.The design features a tapered inner ring and outer ring for line contact, enhancing load capacity vs. point contact to disperse heavy loads and reduce deformation. A stamped steel/brass cage separates rollers to prevent slippage, ensuring high-speed stability and low friction. Some models have outer ring lubrication channels for better heat dissipation and lubrication, extending lifespan.With strong radial/axial load capability, its adjustable clearance meets installation precision. Ultra-precision machining (Ra ≤ 0.8 μm) ensures low friction/noise. Widely applied in heavy machinery, industrial gearboxes, commercial vehicle axles, and large motors for reliable performance.

Product Application

The FODA 32922 tapered roller bearing is engineered to deliver reliable performance in heavy-load, high-precision industrial environments. Its unique design—featuring adjustable clearance, detachable structure, and robust load capacity—makes it ideal for applications requiring both radial and axial load resistance. Below are its primary application scenarios:
1. Heavy-Duty Machinery
  • Applications: Construction equipment (e.g., excavators, bulldozers), mining machinery, agricultural tractors.
  • Role: Supports transmission systems, gearboxes, and rotating shafts subjected to extreme radial loads (e.g., from heavy-duty gears or conveyor belts).
  • Advantage: High radial rigidity and tapered geometry distribute loads over a larger contact area, minimizing deformation and wear under continuous heavy operation.
2. Industrial Gearboxes & Reducers
  • Applications: Industrial gear reducers, speed reducers, and power transmission systems in manufacturing plants.
  • Role: Maintains precise alignment and load distribution in gear meshing processes, where combined radial and axial forces (e.g., from torque and thrust) are common.
  • Advantage: Adjustable clearance ensures optimal meshing precision, while the detachable inner/outer rings simplify maintenance during gear system overhauls.
3. Commercial Vehicle Axle Systems
  • Applications: Truck axles, bus drivetrains, and trailer wheel hubs.
  • Role: Supports the dynamic loads from vehicle weight and road vibrations, while resisting axial forces from braking or cornering.
  • Advantage: Single-row design with directional axial load capacity efficiently handles one-way thrust (e.g., during acceleration), while AISI 52100 steel construction ensures durability in harsh road conditions.
4. Large Electric Motors & Generators
  • Applications: High-power motors in industrial plants, wind turbines, and power generation equipment.
  • Role: Stabilizes rotating shafts under combined radial loads (from rotor weight) and axial loads (from magnetic forces or belt-driven accessories).
  • Advantage: Ultra-precision machining (Ra ≤ 0.8 μm) reduces friction and noise, while lubrication channels (in select models) enhance heat dissipation for long-term reliable operation.

 

Conclusion: The 32922 tapered roller bearing excels in demanding environments where robust load capacity, precision adjustment, and ease of maintenance are critical. It is a trusted solution for industries requiring reliable power transmission and rotational stability, from heavy machinery to high-precision equipment.
