I. Product Structural Features

Tapered Raceway Design?

Features conical raceways on both inner and outer rings, with tapered roller apexes aligned with the bearing axis to achieve pure rolling friction and minimize energy loss. The contact angle α (typically 10°–30°) is customizable, with axial load capacity increasing with angle.

High-Rigidity Configuration?

Supports back-to-back, face-to-face, or tandem mounting arrangements. Preload adjustment enables rigid support systems to accommodate bidirectional axial loads and heavy radial loads.

Modular Component Design?

The inner ring assembly (including rollers and cage) and outer ring can be installed independently for easier field maintenance. The cage is available in stamped steel or solid brass structures to ensure even roller distribution.

II. Core Performance Advantages

Combined Load Capacity?

Simultaneously withstands radial and axial loads, ideal for impact load scenarios.

Optimized Speed Limit?

Reduces frictional heat at high speeds through optimized raceway curvature ratio and surface roughness control.

Environmental adaptability?

SKF Explorer-grade customization available for high-temperature, contaminated, or vibration-prone environments.

III. Typical Applications

Heavy Machinery?

Four-row tapered roller bearings in metallurgical rolling mills and mining equipment optimize load distribution for low-speed, high-load conditions.

Automotive Industry?

Paired bearings on transmission gear shafts provide high rigidity for axial positioning and power transmission.

Energy Equipment?

Wind turbine main shaft bearings compensate for misalignment via preload configurations, enhancing operational reliability.

IV. Selection & Maintenance Recommendations

Installation Precision?

Control coaxiality between shaft and bearing housing to keep angular errors within 2'–4'.

Lubrication Management?

Regularly replenish high-temperature grease and monitor abnormal vibration or temperature rise.
