Cooling water is interrupted.
2. Oil degradation, oil itself is not clean or oil deterioration in operation, such as the increase of oil in the oil will increase the acidity of the oil, will reduce the lubrication of the oil, so that the bearing shell corrosion, resulting in bearing temperature increases.
2 phenomenon:
1. There is an alarm bell ringing.
2. The mechanical disk failure of the machine's hydraulic disc is bright, indicating that the IKO bearing temperature has risen and the signal relay has been activated.
3. Thermometer plate (expansion thermometer) The black and yellow needles coincide or exceed the yellow needle.
4. Issue a fault signal that the bearing temperature has risen.
3 disposal
When IKO bearing temperature rises, first determine whether the malfunction, if indeed increase, should do the following processing:
1. Check the cooling water pressure, water flow and piping system is normal. If the water pressure is low, the filter may be clogged, and if it cannot be disposed of in time, it can be shut down. When it is confirmed that it can work, it can be used again.
2. The governor oil pressure should be checked. If the oil pressure is low, the cooling water hydraulic valve may be closed.
3. Check if the bearing has abnormal noise and check if there is any abnormality in the bearing swing.
4. Take the oil sample to observe whether there is a change in the oil color and perform a test to see if it is deteriorating. If it is confirmed to be deteriorating, it is necessary to stop the replacement of the new oil.
5. Check if the oil level is normal. If it is abnormal, check whether the oil drain valve is closed. If it is tightly closed, it should be filled with oil. If the seal gasket is leaking, it should be shut down.
Basic knowledge of the installation and maintenance of the bearing The important difference between an automobile and an ordinary mechanical bearing is that the bearing is used in a moving environment, so the stress conditions and working conditions are more complicated, and the car is captured as a very precise mechanical part. The installation and use, lubrication and maintenance of the device are essential for achieving the basic functions of capture. China Automotive Bearing Network
Bearing assembly and disassembly Clean the bearing and its associated parts with clean kerosene or gasoline;
Check whether the bearing to be used is consistent with the original model, and whether the matched parts are qualified in size;
The special assembly tool sleeve is used to press the bearing in. The diameter of the tool sleeve cannot exceed the outer diameter of the bearing rib. When assembling, the force should be uniform. Do not impact and brute force assembly.
After the bearing device is completed, the bearing and related components should be turned to check for stuck phenomenon and abnormal noise; inject the specified grease or lubricant according to the requirements of the host component;
When assembling large bearings and bearings with shafts and housings, it is necessary to heat the IKO bearings in an oil bath. The temperature of the oil is about 80 degrees Celsius; when the bearings are assembled, special tools for drawing must be used.

Detail introduction for above main accessories
1.Motor and controller:
The garage door operator is designed for residential overhead sectional and tilt doors.
The operator memorizes the limit positions and unique braking system that slows the unit down at the end of its travel.
Rolling code remote control with max. 20 pcs hand transmitters.
The operator is equipped with a manual release lever which allows manual operation of the door in case of power failure.
The controller has a security LOCK function which prevents operation of the door from transmitter.
2.spring break device:
Sectional doors are hinged and they bend in the tracks as the door opens and closes. Many of these doors are counterbalanced with extension springs, also designated "stretch springs," and they have seven characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - determine the stretch, the distance the spring is extended - normally half the door height, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the percentage of pull needed to separate the coils. This is determined by the pitch with which the springs are wound. On sectional garage door springs this is normally 15 percent. For example a 100 pound pull spring requires 15 pounds of weight to separate the coils; when a door is open the two springs will support 15 pounds of door weight without any stretch.
Most extension springs are made of oil tempered wire. These are normally coated or painted. Some springs are made of galvanized wire.

Determining the right type of sectional door roller for your garage door tracks can be a little confusing, especially when you do not know what you need to look for in a garage door roller. To simplify things, there are two primary things you need to be aware of. First are the actual dimensions of the roller, and second is purpose that you will be using the door for. You can read below about measuring your roller and choosing the right quality of material for your door.
