Bearing Lubrication Maintenance in Sand Making Machine Operation. When the sand maker is working, the possible reasons why the bearing becomes warm are lack of oil, dust in the machine and damage of the bearing. The elimination methods are to add oil or cleanse the bearing and change new bearing. After the fine crushing of the sand maker and the drying process of the dryer machine, the

Bearing Lubrication Maintenance in Sand Making
In the after-sales conversation with HXJQ sand maker customers, we often remind them: After the long-time use of sand maker, you must pay attention to the equipment maintenance job, it is the key to avoid some equipment failures occurring frequently, as well as the guarantee for the normal and stable production of sand making machine. As the key part of the sand maker production, bearing is
Bearing lubrication decisions, made at the machine-design stage, often dictate how well the machine will be maintained throughout its working life. Most design engineers understand how to correctly size a bearing for load or how to choose the proper
The basic functions of bearing lubrication are to: Separate the rolling surfaces; Reduce wear; Minimize the coefficient of friction (i.e. reduce heat) Remove heat generated due to friction; Act as a barrier to the ingress of contamination; Prevent corrosion; Retain rolling elements during assembly for bearings without a
by SKF, the bearing makers, on gearboxes showed that hard particles went from a count of 100 per ml on start-up to about 8000 after 5 hours, to 10,000 per ml after 38 hours. So change or filter your oil in the early stages after commissioning. Then look after it during operation. If metal particles, sand, Figure 7 Particles in Lubricant
The reduced lubrication properties will negatively impact bearing performance. Efforts must be made to renew the grease through replenishment. Figure 1 below reflects the replenishment time intervals for various bearing types running at different speeds. Charts (1) and (2) in the figure are applied based on the use of high-quality lithium soap-mineral oil grease, a maximum bearing temperature
Tools needed for the maintenance of bearings Grease removing agent Oil, grease or gel to lubricate Needle or pin to extract the circlips Waterproof container
This one is very obvious: just like mud on your chain, water and sand make an excellent paste to grind the internal parts of your precious bearings to pieces. In our production facilities we spend an unbelievable amount of time to polish the balls and races that are used for our bearings. After that, we consider the process to be finished. You are probably not going to improve the polish quality during
At a minimum, solid lubrication can free maintenance technicians to focus on more preventative work. At best, it can eliminate an issue that has been causing premature bearing failures. If bearings are continually experiencing problems or premature failure, it may be time to re-evaluate them. It can be impossible to change the circumstances of an application, while it is much easier to employ solutions to combat them. Take, for instance, bearings
To improve bearing life for both labyrinth and lip shaft seals, use an automatic lubricator. Only a small quantity is necessary when slowly flushed into the bearing cavity to force dust and moisture away from the elements. Grease flushing is not practical for oil-filled equipment. A better option is to replace shaft seals at a predetermined frequency just prior to failure.
Monitor bearing temperature continuously or at least periodically. If bearings are operating at more than 180°F, oil service life will likely decrease drastically, even with oxidation inhibitors.
The manufacturer may have designed the bearing to purge through the fill path. For this to be accomplished, you must grease the bearing and then remove the grease fitting to allow excess grease to purge back through the fitting. These bearing operations enable fresh grease to reach the bearing and push out excess grease.
