Agricultural machinery slewing ring bearings

FRB agricultural machinery slewing ring structure is characterized by using flange Bearings, formed in the ring raceway for single row ball bearing, with a full, no gasket.These slewing bearings are neither toothed nor provided with washers and are provided with a surface coating to prevent corrosion.

Benefits:
Low speed rotation, single volleyball flanged slewing bearings for filling machines can withstand axial loads of up to several hundred kilograms.

Special technical features:
FRB Bearings agricultural machinery slewing bearing must be fixed hole, used to install bolts, or ring can be directly welded to the supporting frame.

What caused the damage to the YRT rotary table bearings?

YRT rotary table bearing has also gained great development space.However, some quality issues also emerge.So what caused the damage to the YRT rotary table bearings?FRB Bearings would let you know the reason.

Incorrect installation method
1. Use brute force when installing, and directly strike the bearing with hammer to hurt the bearing the most;Is the main cause of deformation.

2. If the mounting is not in place, there is deviation in the mounting or not installed to the bearing position, resulting in too small bearing clearance.The inner and outer rings are not in the same center of rotation, resulting in different centers.

What's the four characteristics of cross cylindrical roller bearings?

Crossed cylindrical roller bearing can be widely used in machine tool precision rotary indexing  table, vertical and horizontal boring machine, vertical grinding machine, rotary surface grinding  machine, large gear hobbing machine, guns and rotary table, large radio and optical telescopes,  rotating camera, steering pivot and continuous casting machine, highly restricted pivot  microscope platform, pole center axis, bogie, welding stents, turning assembly fixture,  industrial robots, precision rotary worktable, medical apparatus and instruments, measuring  instruments, IC manufacturing equipment and so on.

1. Excellent rotation accuracy
The crossed roller bearings internal structure by roller are arranged 90 ° vertically cross each  other, with intervals between roller device or isolation, can prevent roller friction between  roller tilt goods, effectively prevent the rotation torque increases.In addition, the party will  not have roller contact or lock phenomenon;

The non-standard cross roller bearing can adjust the clearance because the inner and outer rings  are segmented, and the high precision rotary motion can be obtained even when the preload is  applied.

4-point thin wall bearing help you achieve the design high performance, low cost

Internal coordination and anti-corrosion requirements:
Thin-walled four-point contact ball bearings can improve internal coordination and meet the  desired performance requirements.The bearing with preloaded is used for high stiffness and the  bearing with radial clearance is used for low friction torque

In addition, standard cross roller bearings usually have no corrosion protection and are used in  extreme environments for custom sealing, special application grease and high temperature  adaptation.

Plating
According to the super-strong anti-corrosion requirements, the thin and tight chromium coating  can be provided to endow AISI440C with stronger anti-corrosion capability.Unlike many  conventional chromium plating, the coating does not peel or flake off under pressure, thus  maintaining corrosion resistance and minimizing wear.The properties of the coating have been  demonstrated in key military, aerospace and deep space applications.

What's thin wall bearing characteristics and how to maintain?

Thin wall bearing products characteristics
In order to obtain bearing low friction torque, high rigidity and good rotary accuracy, a steel ball with small outside diameter was used.The use of hollow shafts ensures lightweight and wiring space.The thin wall bearing has realized the extremely thin bearing section, also has realized the product miniaturization, the lightweight.

The thin wall series 6700 and 6800 has all kinds of dustproof cover forms, with flange forms, stainless steel forms and wide forms, etc.

Maintenance procedure for thin wall bearing
1. Remove the wheel first. Remember to put the screw in place.

2. Take off the bearing. Some of the core of the wheel is so tight that it is difficult to remove the bearing.use the hexagon plate hand (is the one to remove the screw) to dig it down hard, rest assured, the bearing is not easy to break down!

3. Use the toothbrush to brush off the dirty surface of perine, you do not do this step, there is no difference!

What are the methods to remove the bearing inner and outer rings?

Anyone familiar with slewing bearing knows that it is composed of four parts, including inner ring, outer ring, rolling body and separator.It can bear axial force and radial force at the same time.It is widely used in heavy equipment such as lifting transport machinery, extractors and construction machinery.So, when we want to take out the bearing inner and outer rings what are the methods?Today, let me give you a brief introduction.

The method to remove the bearing inner and outer ring is as follows:
1. Steel ball method: 
3 or 4 steel ball in the damaged bearing rolling body and inner ring shall be distributed evenly inside the bearing outer ring. From the other end of the half axle sleeve pipe, iron bar slightly larger than the bearing inner diameter shall be used to tighten the bearing inner diameter, and it can be struck with hammer.

How to solve the unflexible slewing bearing？

For mechanical products, the slewing ring bearing is one of the indispensable parts, but sometimes we will find that it is not flexible would happen, if it is not flexible, so there will be a lot of trouble in use, and there is no way to good work, FRB Bearings appear to share slewing ring binding or movement inflexible reasons and solutions.

1. The deformation or broken tooth of the swing bearings causes the stuck or the movement is not flexible.
The solution: repair the gear, reweld the gear.

2. There is a problem with the slewing bearing sealing system, which will cause the entry sundries, such as stones, sand, etc. to become stuck or not sensitive to movement.
The solution: get rid of all the clutter.
