When assembling a new bearing, clean the bearing body, end cover, shaft and other assembly parts to prevent dirt, protective coating or lubricating oil from adhering to the bearing. Do not wash the lubricant from the manufacturer to the bearing. The manufacturer uses high-grade acid free lubricant (without chemicals and impurities that may cause corrosion). Any lubricant added must be absolutely clean. To do this, please take the following measures:
1. Cover the sliding cylinder to prevent dirt from entering.
2. Take lubricant with special tools, do not use wood scraper but steel knife or putty knife, because they can be wiped smooth and clean.
3. If a lubricating gun is used, the nozzle and lubricating parts shall be kept clean.
The bearing of slurry pump is an important component and core part of the bearing assembly of slurry pump. The installation of this part directly affects the normal operation and service life of slurry pump
More than 90% of the damage of all roller bearings is caused by dirt. The way of dirt entering into the bearing is due to carelessness before or during assembly, or after the user makes the equipment in working condition.
Dirt is composed of a large number of prismatic hard particles. When mixed with lubricant, it becomes a grinding mixture. In this way, the roller will gradually wear the original precision fit in the rotating motion, reducing the accuracy and efficiency.
The key period that affects the life of the bearing will occur from the time when the bearing leaves the warehouse to the time when the workbench is assembled. The reason is obvious. The bearing is taken out from the box and the protective cover. Since then, the bearing is completely controlled by the staff who manages the bearing. The first rule for managing the bearing is that the tools should be clean and clean wiping cloth should be used instead of waste paper, because the fiber chips and short fibers are easy to stick Attach to the surface, keep hands and workplace clean.

1. Apply oil or light oil to the mounting bearing on the shaft 073
2. Install the butter retaining ring 046 and counter with the flange face of the butter retaining ring
3. Install the bearing cone 009 on the shaft and counter the grease retainer ring with the large end of the cone.
To preheat the inner ring of the bearing, (preheat is not allowed to exceed 250 ° f), we recommend immersing it in a boiling solution of at least one part of water-soluble oil and 100 parts of water. Put the shaft in a vertical position, press the inner ring of the heated bearing onto the shaft, and lean against the butter retaining ring.
4. The installation of the other grease retaining ring and the inner ring of the bearing is the same as above.
B. C, D, e, F and G bracket series
1. Use light oil in the cavity at each end of bearing body 004.
2. Carefully tap the outer ring 009 of the bearing body toward one end of the bearing body with a hammer until it is slightly lower than the end face of the bearing body.
The bearing body is symmetrical. The bearing outer ring can be installed at any end of the bearing body, and the small end of the bearing outer ring is outward. If the bearing body is supported in a vertical position, the assembly will be more convenient.
3. Install the bearing end cover 024 and a gasket 025 into the bearing body, and screw on the bearing end cover, usually 0.018 ″ to 0.020 ″ (0.0457 to 0.0508 mm)
4. Tighten the set screw of the end cover evenly, and the end cover will push the outer ring of the bearing body to the correct position.
