Slewing Bearing Without Gear, SWBTEC slewing bearings without gear usually include ball contact type and crossed roller type. Dimension is from 80mm-2500mm, and the material is 50Mn&42CrMo4. A slewing bearing without gear is widely used on many machines too, like rotators, package machines and lift cranes. As one of the leading slewing bearing manufacturers, whatever special requirement you need, SWBTEC can design and producebearing slewing for you. We also often prepare a stock of forging steel for non-gearswing set bearings, please contact our sales team if you need any size.
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 thebearing for swing set to eliminate part or all of the clearance to achieve preload. How doslewing bearing manufacturers measure preload?
The methodsmall slewing 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
SWBTECbearing slewing ring 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.
