2. Structure, Material & Processing Technology

The RKS.161.14.1094 adopts the classic fixed thin-section lightweight structure of the RKS series. Its cross-section size remains stable regardless of inner and outer diameter changes, featuring an extremely compact overall structure that occupies minimal equipment space and effectively reduces the overall weight and volume of complete machines.

The main body is forged from 42CrMo high-strength bearing steel. The raceways are processed by high-frequency quenching and precision grinding, reaching a hardness of 55-62HRC. It delivers excellent wear resistance, fatigue resistance and impact resistance, supporting long-term operation under alternating loads. The gear parts are machined in strict accordance with DIN 3967 industrial gear standards with precise tooth profiles and stable meshing, greatly reducing transmission noise and mechanical wear.

Equipped with a double-sided contact sealing system and high-quality aging-resistant sealing strips, the bearing effectively blocks dust, sediment, rainwater and other contaminants from entering the interior and prevents grease leakage, adapting to harsh working environments with dust, humidity and open-air exposure. Reserved radial grease nipples support regular manual lubrication and automatic lubrication system matching, realizing low-maintenance operation.

3. Core Performance Advantages

• Multi-directional Composite Load Capacity: The four-point contact ball structure can bear radial load, axial load and overturning moment simultaneously, with balanced force bearing and excellent mechanical stability, suitable for rotary operation scenarios with complex stress conditions.
• High Rotational Accuracy & Low Running Resistance: Precision ground raceways and standard tooth profiles ensure smooth rotation and stable start-stop performance, no stalling at low speed and no jitter at high speed, fully meeting high-precision operation requirements of automated equipment.
• Strong Installation Compatibility: Standard prefabricated mounting bolt holes on both inner and outer rings require no complex modification. It is compatible with various standard mounting bases with simple installation, disassembly and replacement processes, greatly reducing equipment operation and maintenance costs.
• Excellent Weather Resistance: Stable operation in a wide temperature range of -30℃ to +120℃, with outstanding cold resistance, heat resistance and corrosion resistance, adapting to open-air, low-temperature and other harsh working conditions.
• High Cost Performance: The lightweight structure balances high strength and low self-weight. Compared with heavy-duty cross roller bearings, it has lower cost and energy consumption, perfectly matching long-term continuous operation under medium and light load conditions.
