✦ Three-row cylindrical roller configuration – Two axial rows (upper and lower) and one radial row, each with cylindrical rollers arranged in a triangular load path.

✦ Toothless ring design – Both inner and outer rings feature plain cylindrical surfaces without gear teeth, allowing integration with external drive elements.

✦ Monobloc ring construction – Both rings are manufactured as single-piece forgings without welded or bolted joints, ensuring uniform material properties.

✦ Induction-hardened raceways – All raceways hardened to 58–62 HRC with a case depth of 3.5–4.5 mm for extended wear resistance.

✦ Heavy-section rings – Rings feature increased radial thickness with a width-to-height ratio of 1:1.3, optimized for high radial and moment load capacity.

✦ Accepts external drives freely – Toothless rings allow connection to chain, belt, or friction drives without gear-matching constraints.

✦ Reduces system complexity – Eliminating gear teeth simplifies the bearing design, reducing the number of components that require precision inspection.

✦ Lowers initial cost – No gear cutting means reduced manufacturing expense compared to geared versions.

✦ Simplifies cleaning – Smooth ring surfaces do not trap debris, making them easier to clean in dirty environments.

✦ Reduces noise – The absence of gear meshing eliminates a primary noise source, creating a quieter working environment.
