With the development of mechanization, cylindrical roller bearings play a key role in mechanical rotation, mold machinery using bearings is more so, mold machinery is to make the object molding equipment, constituting a lot of parts and components, including bearing parts of the accuracy, speed, stability and its fit with the molding part of the angular contact ball pieces of the performance of the mold machinery has a great impact.The damage rate of the cylindrical roller bearing parts of the mold machinery is relatively high, especially in the work of blanking, forming stamping, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting and so on, the damage of the cylindrical roller bearings is very big.In order to ensure the performance of mold machinery, improve the continuity of production, improve efficiency and increase efficiency, it is necessary to increase the maintenance of cylindrical roller bearing parts, from time to time to overhaul, increase the frequency of overhaul. And require bearing maintenance operators to have a comprehensive knowledge of mechanical maintenance and maintenance. Here we say, cylindrical roller bearings maintenance of key knowledge:1. Usually, the machinery is used to minimize the switching frequency, too much switching equipment will make the cylindrical roller bearing parts wear too fast, affecting the processing accuracy.2. Regular lubrication of cylindrical roller bearings to extend their service time.3. Cylindrical roller bearings and other fasteners, easy to loosen, 2-3 days need to carry out a check to ensure the working accuracy of the equipment.4. The outer ring of cylindrical roller bearings is easy to break, bend and gnaw bad phenomenon, also need to check and replace regularly.5. After long time use of cylindrical roller bearings must be grinding edge, grinding edge surface must be demagnetized, can not with magnetic, otherwise easy to plug.Bearing damage and loss of bearing use is often encountered problems, roller bearing damage and loss of many forms, including corrosion, transportation damage, installation damage, lubrication loss, abrasive wear and fatigue, etc., in order to make the bearing as long as possible to maintain the performance of the bearing itself in a good condition, we must often bearing maintenance, overhaul and abnormal conditions to ensure the reliability of operation. Maintenance is carried out on a regular basis based on the operating standards of the corresponding mechanical operating conditions. The content includes bearing monitoring running status, two types of bearings to replenish or replace the lubricant, regular dismantling of the inspection.Through the above content we can understand in detail some of the knowledge about the maintenance of cylindrical roller bearings, which is very helpful for us to better use in the future, we sincerely welcome the majority of users to come to our company to consult and buy the appropriate cylindrical roller bearings....

In order to provide bearings in the work of the operating speed, in general, will use grease or lubricating oil to lubricate bearings, we are in the grease lubrication method for sealing into the lubricant? According to the use of different types of bearings, the bearing grease sealing method will be different, according to the knowledge of bearing maintenance, the following focus on analyzing the bearing grease sealing method.Precautions for sealing bearing grease:Different sealing methods of grease will result in unstable temperature rise during initial break-in operation, abnormal temperature rise, long initial break-in time, and even sintering, therefore, it is necessary to adopt the appropriate amount of grease and the correct sealing method according to the conditions of use.1、Confirmation before sealingMake sure there is no residue inside the bearing. It is recommended that bearings for high-speed spindles be cleaned, degreased, and then sealed with grease. For other conditions of use, it is also recommended to remove the rust preventive oil adhering to the inside of the bearing.2. Sealing of greaseIn order to seal in the proper amount of grease, it is recommended to use a sealer. For the sealer, use a gauge with a sealing reading.3、Grease sealing amountPrecision bearing standard recommended sealing amount:Angular contact ball bearings for high-speed spindles - 15% of the volume (-2%~+2%)Cylindrical roller bearings for high-speed spindles - 10% of the space volume (-2%~+2%)Ball bearings for motors - 20%~30% of the space volume.The way of bearing grease sealing in:1、Method of sealing in grease for ball bearings(1) Between the steel balls, seal in evenly. If the guide of the cage is the outer ring guide phenol resin cage, it is recommended to apply grease thinly on the guide surface of the cage.(2)Turn the bearing by hand, so that the grease is evenly sealed into the raceway surface, the inner diameter part of the cage, between the steel balls, and the guiding surface, so that the grease fills the internal space.2、The grease sealing method of cylindrical roller bearings(1) 80% of the sealing amount of grease, evenly coated on the rolling surface. At this time, it is recommended that the inner diameter of the cage should not be too much grease. The grease on the inner side of the cage is more difficult to flow during the initial break-in operation stage, which increases the temperature rise and also prolongs the break-in operation time.(2) Smear the grease on the rolling surface of the rollers to the end face of the rollers, the cage, the contact part with the rollers, and the entrance of the pockets, so that the grease is evenly distributed to the bearing as a whole.(3) Apply 20% of the sealed-in amount of grease, evenly and thinly, to the outer ring rolling surface of the sleeve in the bearing chamber....
