32094101-Crossed Rollers 07 Bearing

The 07 series is a specialized range of single-row crossed roller slewing bearings featuring internal gearing, engineered for applications that demand a harmonious balance of compact dimensions, high rotational precision, and substantial load-carrying capability. This series is recognized for its robust construction and versatility across a wide spectrum of industrial sectors.


Typical Areas of Application:

Industrial manipulators and robotic positioning tables

Turntables and rotary indexing units for assembly lines

Crane slewing mechanisms and aerial work platforms

Medical imaging systems and diagnostic scanning equipment

Radar, antenna, and optical tracking pedestals

Wind turbine pitch adjustment and yaw control systems



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

✦ Roller arrangement – Cylindrical rollers are positioned with their axes alternating at 90° in a single raceway, enabling each roller to maintain line contact with both raceways simultaneously.

✦ Internal gear teeth – The inner ring bore features integrally cut gear teeth with a 14.5° pressure angle, reducing sliding friction during meshing.

✦ Split outer ring – The outer ring is manufactured in two halves, joined by dowel pins and cap screws, allowing easy assembly around existing shafts.

✦ Raceway finish – Raceways are superfinished to 0.2 µm Ra, minimizing rolling resistance and heat generation at high speeds.

✦ Carburizing treatment – Rings undergo case-carburizing to a depth of 1.5–2.0 mm, creating a tough core with a wear-resistant surface of 60–64 HRC.

✦ Labyrinth seal design – The rings feature interlocking labyrinth channels that provide non-contact sealing, eliminating wear while excluding coarse contaminants.


Features

✦ Reduces sliding friction during gear meshing – The 14.5° pressure angle design minimizes tooth sliding, lowering power loss and heat generation.

✦ Enables assembly in confined spaces – The split outer ring construction allows the bearing to be installed around existing shafts without complete disassembly.

✦ High-speed operational capability – The superfinished raceway surface (0.2 µm Ra) ensures low rolling resistance, supporting elevated rotational speeds.

✦ Absorbs shock loads effectively – The case-carburized structure provides a tough core that withstands impact forces while maintaining surface hardness.

✦ Extends seal life – Non-contact labyrinth seals eliminate friction-related wear, ensuring long-term protection against contaminants.

✦ Adapts to non-standard mounting interfaces – Customizable bolt hole configurations allow direct integration with existing machinery without adapters.
