What's the slewing bearing selection and maintenance method?

Slewing bearing itself has the characteristics of compact structure, easy to guide rotation, easy to install and maintain, etc., and is widely used in lifting and transportation machinery, excavator, construction machinery, and other large rotary devices.Today FRB Bearings introduce how to select and maintain the slewing ring.

Selection slewing ring bearing method
In the selection of slewing bearing must choose the appropriate model, we also know that there are many slewing bearing models, if you do not know what kind of model you need, you can ask the manufacturer, they will tell you.Also pay attention to the slewing ring clearance, if the clearance is too large to lead to high temperature, so in the purchase is to consider the clearance problem.The last point is to see the smooth surface of the slewing ring, there can be no defects or impurities, otherwise it will affect the normal use.

Maintenance slewing ring bearing method
slewing ring bearing can bear increased axial load, rotation, transmission as one of the large bearings, often use machinery, food machinery, large playground.

1. Check the device surface when installing the slewing ring bearing to see whether there are cracks, burr and other problems on the surface. At the same time, the upper and lower dislocation should not be allowed during the installation.

2. Check whether the slewing ring bearing is loose after work every time. If the screw is loose, tighten the bolt.

Through the above introduction, we learn about the slewing ring bearing selection and maintenance methods, Please share it with your friends!

RKS.062.25.1644 Replacement Of ROTHE ERDE, TG, IMO Slewing Ring Bearings

Feature Products:
slewing ring bearing are usually used for low revolution while shaking and strained with an force.

Product Description:
FRB Slewing ring bearings are usually used for low revolution while shaking and strained with an enormous axial force, moment and in some parts with radial force simultaneously.

Consequently the requirements for loading are stricter than ordinary bearings. If the selection of the bearing has been wrong it will cause a great damage. Hence it is necessary to evaluate the exact forces acting on the slewing ring bearing and to select the suitable slewing ring bearing.

Several key problems affecting the slewing rings manufacturing

Slewing ring Bearings are commonly used in modern industrial components, compact structure, convenient guide rotation, simple installation, easy maintenance, which is widely used in lifting the transport machinery, mining machine, construction machinery, port machinery, wind power generation, medical equipment, the radar and missile launcher and other large rotary device. FRB Bearings would briefly introduce, the several key problems affecting slewing ring manufacturing.

Slewing ring bearings manufacturing furnace temperature and heating speed
1. Carbon steel, alloy steel, normalizing furnace charging requirements bottoms in less than or equal to the processing temperature furnace, the furnace temperature, alloy structural steel, alloy tool steel annealing requirements under 550 ℃ furnace charging, along with the furnace heating up.

2. High speed steel and complex differential cross section larger easy low temperature furnace charging, and mean temperature between 550-700 ℃ with the furnace heating up after 1 to 2 hours.

What's the thin section ball bearing features?

FRB Bearings produce thin wall bearing which can be divided into seven open series and five seal series.

The internal diameter ranges from 1 inch to 40 inches, and the cross-sectional dimensions range from 0.1875 x 0.1875 inches to 1.000 x 1.000 inches.

Open series have three types: radial contact (type C), angular contact (type A) and four-point contact (type X).

Sealed bearings have two types: radial contact (type C) and four-point contact (type X).

What's the Installation and operation instructions of cross roller bearing?

Compared with ordinary bearings, the accuracy of cross roller bearings is higher, so the use of  the corresponding caution, otherwise it will affect the working life of the bearing.

1. Cross roller bearings, which have been injected with German high quality grease before  delivery, can be installed and used directly by users.Grease should be changed every 3 to 6  months.In the early stage of bearing use, due to the resistance of grease, the friction torque of  bearing will be relatively large, and when the excess grease overflows, the torque will return to  the normal value.

2. The inner ring or outer ring divided shall not be separated after being fixed with bolts and  nuts, and can be directly loaded into the bearing seat for use.At the same time, if the assembly  of the isolation block inside the bearing is wrong, it will have a great impact on the rotating  performance and rolling body force, so please do not disassemble the bearing casually.

   1). The seam of the inner ring or outer ring sometimes deviates somewhat.Before loading the  bearing seat, loosen the bolts fixing the inner ring or outer ring, and fix them with a plastic  hammer before installing.

Crossed Roller Bearing, High Rigidity -- CRBH Series

Crossed Roller Bearing is a bearing with compact structure in which the rollers are arranged so that they cross between the inner ring and the outer ring. Since the rolling surface is line contact, elastic displacement based on bearing load is extremely minimal, and in addition, it is able to receive complicated loads consisting of radial load, axial load, and moment at the same time. This bearing is broadly used in revolving parts that require compactness, high rigidity, and revolution accuracy such as industrial robots, machine tools, and medical equipment. Furthermore, we also manufacture bearings made of stainless steel, and those with attachment holes in inner and outer rings, so please make inquiries at FRB Bearings.
