RKS.061.30.1904-RKS.061 Series with external gear teeth

The RKS.061 series is a medium-sized, single-row four-point contact ball slewing bearing with an external gear on the outer ring. It is designed to handle combined loads – axial, radial, and tilting moment – simultaneously in a compact configuration.


Typical Applications:

Mobile cranes and lifting platforms-

Construction and handling equipment

Excavators and aerial work platforms


High load-carrying capacity
Resistance to high and low temperatures
Noise-free operation
Strictly controlled tolerances and appropriate internal clearance
Long service life and low maintenance requirements
Prevention of unexpected downtime (avoiding bearing fracture, seizure, and safety incidents caused by such failures, with anti-tilting capability)

Characteristics

✦ 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.


Features

✦ 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.
