Slewing Bearing Without Gear Features and Benefits

There are not too many slewing bearings without gear in our normal order. Some customers require that the slewing bearing without teeth must have a preload. In order to meet the needs of customers, our technicians have developed the preloaded slewing bearing production process and measuring process successfully.

In general, it relies on the axial displacement between the inner and outer small slewing ring of the bearing to eliminate part or all of the clearance to achieve preload. How do slewing bearing manufacturers measure preload?

The method slew ring bearing manufacturers use is the starting torque method: measure the starting tangential force with a tension meter, and calculate the starting torque. After the torque is obtained, the preload is estimated by the relationship between the starting torque and the preload.

Slewing Bearing Without Gear Application

SWBTEC slewing bearing without gear is widely used in JIB cranes. JIB crane is an industrial component and is a light-duty crane with light working strength. It consists of a column, a slewing arm, a slewing drive device, and an electric hoist. The lower end of the column is fixed on the concrete foundation by anchor bolts. For the application of this kind of slewing bearing, it is necessary to add lubricating grease regularly according to the working environment to protect the raceway. The raceway should be filled with lubricating grease after 50 working hours for the first time, and then every 300 working hours after that. The slewing bearing must be filled with grease before and after being placed for a long time. Filling grease should be carried out under the condition of slow rotation of the slewing bearing. When the grease overflows from the seal, it means that the filling is completed.

How Does a Slewing Bearing Without Gear Work

A slewing bearing without gear consists of an inner and outer ring with rolling elements (usually balls or rollers) sandwiched between them. The rolling elements facilitate smooth rotation between the rings, allowing the bearing to support and transmit loads. These small slewing bearing is often used in applications where an external gear or drive mechanism is employed separately for rotational motion.

Slewing Bearing Without Gear FAQs

Q What materials are commonly used in the construction of slewing bearings without gear?

Slewing bearings without gear are typically made from high-quality steel, such as chrome-molybdenum steel or stainless steel, to provide strength, durability, and corrosion resistance. The choice of material depends on factors like load capacity, operating conditions, and cost considerations.
Q Are slewing bearings without gear prone to corrosion?

While the small slewing ring can be susceptible to corrosion if not properly protected, the use of corrosion-resistant materials and appropriate surface treatments can significantly enhance their resistance to rust and corrosion. Regular maintenance and lubrication are also important to prevent corrosion and ensure optimal performance.
Q How do I select the right size and type of slewing bearing without gear for my application?

Selecting the appropriate slewing bearing without gear involves considering factors such as load requirements, operating conditions (including speed and temperature), installation space limitations, and required service life. It is recommended to consult with manufacturers or engineering professionals who specialize in slewing gear bearing to ensure proper selection based on your specific application parameters.
