✦ Raceway geometry – The single raceway is ground with a logarithmic roller profile, optimizing contact stress distribution along the roller length under varying loads.
✦ Gear tooth form – Internal gear teeth feature a modified involute with tip relief, reducing mesh impact noise during start-stop cycles.
✦ Ring cross-section – Rings are designed with an asymmetric cross-section, thicker on the gear side to absorb meshing forces while reducing weight on the opposite side.
✦ Heat treatment process – Rings undergo a two-step heat treatment: through-hardening followed by localized induction hardening of raceways and gear flanks.
✦ Sealing interface – Seal grooves are machined with a dovetail profile, providing mechanical retention for rubber seals without adhesives or retainers.
✦ Mounting hole arrangement – Bolt holes are drilled in alternating counterbore and threaded patterns, allowing flexible mounting options on either ring.
