I. Product Positioning: A Typical Representative of Self-Aligning Ball Bearings
It belongs to the double-row self-aligning ball bearing category. Its core value lies in "automatic self-alignment + composite load bearing", designed for equipment with limited installation precision and complex load conditions (e.g., shaft misalignment, vibratory operations).
II. Core Parameters
Aspect
Details
Dimensions
Bore diameter: 25 mm (the "05" in the model corresponds to 05×5 = 25 mm); Outer diameter: 62 mm; Width: 17 mm.
Load Capacity
Dynamic rated load: ~18 kN; Static rated load: ~5 kN (suitable for medium-heavy loads and impact resistance).
Rotational Speed
Grease lubrication: ≤10,000 rpm; Oil lubrication: ≤13,000 rpm (low-friction design supports medium to high speeds).
The spherical raceway + double-row ball structure automatically compensates for shaft misalignment (≤2°) and installation misalignment, reducing the risk of bearing seizure.
2. Multi-Load Adaptability
It simultaneously bears main radial loads + bidirectional auxiliary axial loads, adapting to impact and vibratory conditions (e.g., crushers, reducers).
IV. Typical Application Scenarios (Covering 10+ Industries)
Energy & Chemical Industry: Drilling/production equipment (heavy loads), high-purity water production equipment (low contamination), water-cooled chillers (medium-speed operation).
V. Selection & Replacement Recommendations
Advantages: Strong self-alignment capability, moderate cost — ideal for scenarios with rough installation and complex loads.
Limitations: Weaker axial load-bearing capacity than thrust bearings; lower high-speed performance than angular contact ball bearings.
