SKF Bearings is early retirement; replacement grease too much, the two complex issues about bearing maintenance is time to replace the grease and how much oil should be change. If replacing the grease too little. The bearings will fall into hardship or temporary damage to the power coil and reel. Lubrication intervals on a simple premise: the bearings do not stop the operation of the conditions to maintain a reasonable operation of the equipment due to drying and disintegration. This is a fixed concept of prevention. But is necessary to adhere to the balance between the lubrication thirst and excessive lubrication. Lubrication plan is scheduled to equipment suppliers usually depending on the operating time to develop a lubrication plan. SKF bearings and equipment suppliers in the maintenance planning process, often by adding the amount of lubricating oil guide.
Bearing clamping force adjustment: In order to prevent possible bearing rotation and axial movement of the process, in addition to the interference and stop part, SKF Bearings must also be used to compress the bearing caps, measurement methods and measuring the same headspace measurement of the thickness soft wire, clamping force can be used to calculate the bearing (bearing elastic deformation, compression)
General Bearing 0.02 to 0.04 mm of compression force. If the clamping force does not meet the standards, can increase or decrease the thickness of the bearings and spherical plain bearings in the method of adjusting pads, tile fill is not allowed.
In addition to the SKF bearing radial clearance to ensure that, should also ensure that the axial clearance. Detect axial clearance, shaft will move into an extreme position, and then use a feeler gauge or dial indicator measuring axis position, from one extreme to the other extreme position of beating the axial clearance.
When the bearing clearance does not meet the requirements should be adjusted. Split bearing radial clearance is often used to make up (top space). Short-term replacement of oil is a very rare thing. Often added to grease the high side. Such as requiring every two to Samsung to replacement of a lubricating oil, and each time you add an ounce of grease. These proposals would cause him some do not know of any practical significance factors are established need to replace the grease bearing quality is better, no matter what bearing. Operation, replace the grease is essential although the bearings period of time without replacing the grease will not be a problem, but a long time without replacing the grease, then, it will affect the SKF bearing life. To pay attention to the SKF bearings to replace the grease, so I use the use of bearings. The oil-for-bearing abilities to properly operate.
