✦ Three independent roller rows – Separate rows for axial (upper/lower) and radial loads, each with dedicated raceways and roller sets.
✦ Cylindrical roller geometry – All rows use cylindrical rollers with line contact for high stiffness and load capacity.
✦ Separate raceway rings – The axial raceways are machined into separate ring sections, while the radial raceway is located on the inner ring circumference.
✦ Induction-hardened raceways – Each raceway is hardened to 58–62 HRC with a case depth of 3–4 mm for extended wear life.
✦ Heavy-section ring design – Rings feature increased cross-sectional thickness (height-to-width ratio of 1.2:1) to resist deformation under high loads.
✦ Cage-guided rollers – Rollers in all rows are retained by machined brass or steel cages to maintain spacing and reduce friction.
