✦ Three-row cylindrical roller configuration – Two axial roller rows (upper and lower) positioned on either side of a radial roller row, forming a compact triangular load path.
✦ Internal gear on inner ring – Gear teeth are integrally hobbed on the inner ring bore, featuring a 20° pressure angle spur profile with induction-hardened tooth flanks.
✦ Segmented outer ring – The outer ring is manufactured in two halves (upper and lower) that are bolted together after roller assembly, simplifying installation in confined spaces.
✦ Distinct raceway geometry – Each roller row has its own raceway curvature and contact angle – axial rows at 45° and radial row at 0° – optimizing load distribution.
✦ Induction-hardened raceways – All raceways hardened to 58–62 HRC with a case depth of 4–5 mm, while gear teeth maintain a separate hardness of 50–55 HRC.
✦ Ring material specification – Manufactured from 42CrMo4V steel with improved purity and homogeneity, specifically selected for high-temperature applications.
