✦ Direct external gear drive – Gear teeth cut on the outer ring allow direct meshing with a drive pinion for precise rotary actuation.

✦ Four-point contact ball design – Single-row configuration with balls contacting the raceway at four points, handling axial, radial, and tilting moment loads in one unit.

✦ Medium-duty compact format – Belongs to the RKS medium-size range, delivering solid load capacity without excessive bulk.

✦ Raceways induction hardened – Heat-treated rolling surfaces combined with optimized contact angles give the bearing reliable rigidity and rotational accuracy.

✦ Bolt-on installation – Pre-drilled mounting holes (threaded or through) on both rings let you secure the bearing directly to adjacent structures with standard fasteners.

✦ Effective contamination sealing – Equipped with NBR rubber seals (standard or optional) to keep dirt and moisture out while retaining the lubricant.

✦ External gear on outer ring – Direct pinion engagement for rotary motion.

✦ Four-point ball contact – Handles axial, radial, and moment loads simultaneously.

✦ Compact medium-duty size – Good strength-to-size ratio.

✦ Hardened raceways – Wear-resistant and dimensionally stable.

✦ Mounting holes pre-drilled – Ready for bolted installation.

✦ Seals available – Keeps out dirt and moisture.

✦ Steel construction – Built for crane and material-handling applications.
