FAG HCS71914-E-T-P4S-DULThe HCS71914 E T P4S DUL FAG is a high speed design hybrid spindle bearing (pair). This bearing type has seals on both sides, and small ceramic balls. Hybrid spindle bearings can reach very high speeds with very little heat generation and wear. Even at very high speeds, a high degree of rigidity is maintained. This makes the HCS71914 E T P4S DUL FAG particularly suitable for use in high speed or machine tool spindles. B = Standard steel balls 70 =
