Rear Wheel Bearing

The performance and longevity of the 30205 Bearing are fundamentally rooted in its material science and precision manufacturing.

Premium Bearing Steel and Heat Treatment

The core components—inner ring, outer ring, and tapered rollers—are manufactured from high-carbon chromium bearing steel,  This material is selected for its inherent hardness, excellent fatigue resistance, and capability to withstand high contact stresses. A precisely controlled heat treatment process is subsequently applied. This involves through-hardening or case-carburizing to achieve an optimal microstructure, resulting in a hard, wear-resistant surface coupled with a tougher, more ductile core. This balance is crucial for the 32025 tapered roller bearing to absorb shock loads without brittle fracture.

Advanced Component Engineering

The 32025 Bearing incorporates a pressed steel cage, typically made from low-carbon steel. This cage accurately spaces and retains the tapered rollers, ensuring even load distribution and maintaining optimal alignment during high-speed operation. Furthermore, the geometric design of the rollers and raceways is engineered to minimize internal friction and control the contact stress pattern, which directly contributes to the extended service life of the 32025 bearing. All surfaces are finished to a micro-level smoothness, reducing friction and the initiation points for fatigue.

Technical Features & Operational Advantages

The design of the 32025 Tapered Roller Bearing confers several distinct advantages in demanding operational environments.

Superior Load Capacity and Stability

The primary advantage of the 32025 Bearing is its ability to support significant combined loads. The angled configuration of the rollers allows it to simultaneously carry high radial loads and substantial axial (thrust) loads in one direction. This makes the 32025 bearing for heavy-duty applications an ideal choice. Its rigid construction and precise roller guidance ensure exceptional operational stability, minimizing axial and radial runout, which is vital for the smooth running of precision machinery.

Optimized Friction and Long Service Life

Precision grinding of all contact surfaces leads to exceptionally low friction and heat generation. When paired with appropriate high-quality grease, this results in high rotational efficiency. The synergistic effect of premium materials, optimal heat treatment, and superior surface finish culminates in a remarkably long fatigue life rating (L10). This translates to reduced unplanned downtime and lower total cost of ownership, making the 32025 Bearing a cost-effective solution.

Interchangeability and Simplified Maintenance

As a bearing with standard 32025 bearing dimensions (125mm bore, 215mm OD, 47mm width), it is manufactured to international metric standards. This ensures direct interchangeability with equivalent bearings from major global brands providing flexibility in sourcing. Its standardized design also simplifies inventory management, maintenance planning, and on-site replacement procedures.

Typical Industrial Applications

The robust design and versatile load-capacity profile of the 32025 Bearing make it suitable for a wide range of industrial sectors.

Gearboxes and Drivetrain Systems: It is commonly installed in the shafts of industrial gear reducers, vehicle transmissions, and final drives, where it manages combined radial gear forces and axial thrust loads.

Heavy-Duty Rotating Equipment: This includes applications in construction and agricultural machinery bearings, such as wheel hubs, idlers, and roller supports, where high shock loads and contamination exposure are prevalent.

Material Handling and Conveyor Systems: The 32025 Bearing is employed in the rollers, pulleys, and drive shafts of conveyor systems, reliably supporting radial loads and occasional axial misalignments.

General Industrial Machinery: It serves reliably in pumps, electric motors, and industrial fans of moderate size, providing stable and durable rotational support.
