✦ Roller-race interface – Each cylindrical roller maintains line contact with both raceways through a 90° alternating orientation, creating a stiff, compact load path.

✦ Plain ring surfaces – Both rings are machined without gear teeth, providing smooth cylindrical surfaces for flexible external drive attachment.

✦ Ring production method – Rings are produced from vacuum-degassed steel forgings, ensuring high purity and uniform grain structure.

✦ Raceway micro-geometry – Raceways are finished with a micro-ground surface (0.25 µm Ra) and a slightly crowned profile to prevent edge loading.

✦ Surface enhancement – Rolling surfaces receive a combined induction hardening and sub-zero treatment, achieving 60–64 HRC with retained austenite below 5%.

✦ Seal groove profile – Seal channels are machined with an asymmetric dovetail profile, allowing snap-in seal installation without adhesives.

✦ Prevents edge loading – The micro-ground raceway with crowned profile eliminates stress concentration at roller ends, extending bearing life.

✦ Ensures dimensional stability – The sub-zero treatment reduces retained austenite, minimizing dimensional changes over time.

✦ Simplifies seal installation – The dovetail seal groove allows snap-in installation without adhesives, speeding up assembly.

✦ Provides flexible mounting – Alternating threaded and clearance holes allow attachment from either side, simplifying integration.

✦ Enables high-speed operation – The low surface roughness and optimized roller geometry reduce heat generation at elevated speeds.

✦ Adapts to custom drives – Toothless rings allow direct coupling to belts, chains, or friction drives without gear matching.
