Used in hydraulic pumps, gearboxes, machine tool spindles, and aerospace actuators where pure axial loads dominate. Unlike generic thrust bearings, this model features tighter raceway geometry tolerances and superior surface finish (Ra ≤ 0.2 μm), reducing heat generation by up to 22%. Backed by 100% dimensional inspection and dynamic load validation per ISO 76. FAQ: Q: Is preload adjustable? A: Yes — separable design allows precise preload tuning. Q: Can it handle shock loads? A: Rated for intermittent shock up to 1.5× static load (per ISO 281). Q: What’s the max speed? A: Up to 2,800 rpm (grease-lubricated, light load).
