A 15° contact angle keeps the load path near the radial plane, cutting ball centrifugal and gyroscopic effects, so the set runs faster and cooler than a 25° or 40° equivalent. The triplex stack recovers thrust capacity: the tandem pair shares thrust in the heavily loaded direction, roughly doubling capacity that way, while the single opposing bearing takes the lighter reverse thrust and completes axial location of the shaft.
Drilling and boring spindles, machine-tool spindles with strongly asymmetric thrust loading, and high-speed shafts needing heavy one-way thrust capacity.
Unit Quantity: 1 set of 3 Pcs — matched DBT triplex stack. Two bearings mounted in tandem facing one direction and a third facing the other, giving a back-to-back relationship overall.
