Dentail

Dual Angular Contact Configuration：Two rows of balls arranged symmetrically at specified contact angles (typically 30°/40°), enabling simultaneous radial (Fᵣ), bi - directional axial (±Fₐ) and moment (M) load capacities
Brass Retainer Technology：Precision - machined from high - strength brass (CuZn39Pb3), providing:
✓ Uniform ball spacing (adjacent ball pitch deviation ≤0.05mm)
✓ Dynamic balance optimization
✓ Enhanced self - lubrication

Stiffness Enhancement：40% higher axial stiffness in preloaded condition (vs single - row bearings)
Extended Life：Vacuum - degassed bearing steel (SUJ2) with brass retainer ensures L₁₀ life of 3,000h (P2 class)

Application

The bearings can be used in the following industries

Machine Tool Spindles：CNC machining center spindles (18,000rpm, radial runout ≤3μm)
Aerospace Drives：Helicopter main gearboxes (2,000N·m torque capacity)
Precision Instruments：Centrifuge drum supports (unbalance ≤5g·mm)
Industrial Robots：SCARA robot XY axes (repeatability ±0.01mm)
