✦ Four-point contact ball design – Single-row configuration handles axial, radial, and tilting moment loads in one raceway.
✦ External gear on outer ring – Teeth cut on the outer ring allow direct pinion engagement for rotary drive and positioning.
✦ Ready-to-mount – Both rings come with pre-drilled mounting holes (threaded or through) for bolted installation.
✦ Standardized clearances – Radial clearance 0 to 0.05 mm, axial tilting clearance 0 to 0.08 mm across the series.
✦ Induction-hardened teeth – Gear teeth are heat-treated for wear resistance and bending strength.
✦ Compact cross-section – Uniform 56 mm section height throughout the series, with ring widths at 44.5 mm.
✦ Broad size range – Bore diameters from 342 mm to 1,024 mm, covering medium to large rotary applications.
