General purpose grease cannot meet the needs of various special bearing applications.Use only one or more general purpose greases to satisfy all miniature bearing applications.The problems caused will far exceed the advantages brought by the same trademark. The operating conditions of bearings are very diverse. Correct lubrication requires the grease to match the operating conditions of the bearing, because the temperature is affected by lubrication, speed, load, and environment.The values ​​in the table only represent the approximate temperature range. The effect of bearing lubrication. Lubrication has a major impact on the fatigue life and friction, wear, temperature rise, vibration, etc. of rolling bearings. Without normal lubrication, the bearing cannot work. Analysis of the factors of bearing damage shows that about 40% of NSK imported bearing damage is related to poor lubrication.In addition, bearing lubrication also has many functions such as heat dissipation, anti-rust, sealing, smooth buffering, etc. The effects of bearing lubrication can be briefly explained as follows: 1. Bearing maintenance: Bearing cleaning: When disassembling the bearing for maintenance.
First record the appearance of the bearing, confirm the remaining amount of lubricant, and take a sample of the lubricant for inspection.Washing bearings, therefore, good lubrication of miniature bearings is an effective measure to reduce bearing friction and wear.As a cleaning agent, gasoline and kerosene are generally used to clean the disassembled bearings. They are divided into coarse cleaning and fine cleaning. They are placed in containers and placed on the bottom so that the micro bearings do not directly touch the dirt in the container. During rough cleaning, if the nsk imported bearings are contaminated with dirt.It will damage the rolling surface of the bearing. You should pay attention to it. In the coarse cleaning oil, use a brush to remove the grease and stickiness. After it is roughly clean, move to fine cleaning. Bearing maintenance: In order to maintain the original performance of the bearing in good condition for as long as possible, it must be maintained and repaired to prevent accidents before they happen and ensure the reliability of work.Improve productivity, economy, and maintain the work standards corresponding to the working conditions of the machinery, which should be carried out regularly. The content includes working conditions, replenishing or replacing lubricants, and regular disassembly inspections.
Maintenance matters at work include bearing noise, vibration, temperature, lubricant status, etc. Bearing maintenance and judgment: In order to judge whether the disassembled micro bearing can be used.Check after the bearing is cleaned to check the condition of the raceway surface, rolling surface, matching surface, wear of the cage, increase in clearance of nsk imported bearings and damage related to reduced dimensional accuracy. For abnormal, non-separable small ball bearings, use one hand to support the inner ring horizontally, confirm whether the outer ring is smooth, and finely clean.The bearing is carefully cleaned while immersed in clean oil. Bearing products are sometimes produced in large batches and cannot be inspected. So what kind of sampling plan should be selected and how much quantity should be selected for inspection, so that the quality of the imported bearings of the overall product can be more comprehensively and reliably represented, and the inspection results are measured according to what standards.In order to determine whether this batch of products is a qualified batch that should be accepted, or a substandard batch that should be rejected, we will introduce the bearing load calculation for us.
