ODM External gear single-row ball type swivel bearing Suppliers, Factory

The gear processing is carried out on the outer circumference of the outer ring. The outer ring serves as both the bearing ring and the driving gear ring. By engaging the driving small gear with the outer teeth of the outer ring, rotational power is transmitted. When the small gear rotates, it drives the outer ring to rotate. At this time, the inner ring is usually fixed to the base (frame) and the outer ring rotates, driving the upper structure it is connected to (such as the upper frame of the excavator) to rotate as well. The steel balls have four-point contact with the inner and outer ring raceways, capable of simultaneously bearing axial loads, radial loads and overturning moments, meeting the requirements of combined force conditions. It has the characteristics of compact structure, composite load-bearing and active transmission, and is suitable for the power rotation requirements of medium and light equipment.

Product Description

Performance Features

Direct & Efficient Transmission

The external teeth mesh with the driving gear for transmission. The transmission ratio is accurate, the operation is smooth, and it can achieve controllable rotational movement. No external additional driving mechanism is required.

Low Operating Resistance

The rolling friction coefficient of the steel balls is low, the rotation is flexible, and it is suitable for material handling and rotary operations of construction machinery.

Easy Maintenance

The sealing device can effectively prevent the leakage of lubricating oil and the intrusion of dust and impurities. Regular addition of lubricating oil can maintain good working conditions. The wear condition of the gear meshing surface needs to be checked regularly.

Typical Application Scenarios

It is widely used in small and medium-sized cranes, excavators, loaders, rotary conveyors, concrete spreading machines, welding operation machines, small port machinery and environmental protection equipment, especially suitable for medium and light-duty equipment that requires active power rotation and has moderate load.

Frequently Asked Questions (FAQ)

Q1 What are the primary applications of the 01 Series external gear type bearing?

It is ideal for small to medium-sized cranes, excavators, loaders, rotary conveyors, concrete spreading machines, welding stations, environmental protection systems, and similar light-to-medium-duty rotary machinery.

Q2 Why choose an external gear design for slewing bearings?

The external gear design allows direct meshing with the drive gear. This delivers an accurate transmission ratio, guarantees smooth operation, and eliminates the need for complex external driving mechanisms.

Q3 How should the 01 Series bearings be maintained?

Maintenance is straightforward. Ensure regular lubrication to prevent friction, check the integrity of the sealing device (which guards against dust and impurities), and periodically inspect the wear status of the gear teeth.

Q4 What factors contribute to the low operating resistance of these bearings?

The low operating resistance is achieved through a optimized rolling configuration using steel balls. This minimizes the friction coefficient, resulting in highly flexible and efficient rotational movement.

Q5 Are these bearings compatible with heavy-duty operations?

These bearings are specifically designed for medium and light-duty equipment requiring moderate load capacity and active power rotation. For extreme heavy-duty needs, larger model series should be consulted.
