Non-standard bearing anti-rust method

1. Surface cleaning: Cleaning must be based on the nature of the surface of the rust-preventing material and the conditions at that time. Commonly used are solvent cleaning, chemical cleaning and mechanical cleaning.

2, the surface is dry: after cleaning, it can be dried by filtered dry compressed air, or dried by a dryer at 120-170 °C, or dried with a clean gauze.

Non-standard bearing method for applying anti-rust oil:

1. Immersion method: Some small items can be immersed in anti-rust grease, so that the surface is adhered with a layer of anti-rust grease. The oil film thickness can be achieved by controlling the temperature or viscosity of the rust preventive grease.

2, brushing method: for outdoor construction equipment or special shape products that are not suitable for soaking or spraying, it is necessary to pay attention not to accumulate when brushing, but also to prevent leakage coating.

3, spray method: some large rust-proof materials can not be immersed oil, generally with a pressure of about 0.7Mpa of filtered compressed air in the air cleaning place for spraying. The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil, but it must adopt perfect fire and labor protection measures.

Through the introduction of the anti-rust method for non-standard bearings above, everyone should be clear at a glance. The rust prevention of non-standard bearings is to remember two major steps, one is to clean, and the other is to apply anti-rust oil. The specific steps of the specific steps, the above also clearly explained, I believe that everyone knows how to operate.

NSK bearing inspection and acceptance instructions

To check NSK bearings, the user must have the following knowledge:

1. Which standard is used for the inspection of NSK bearing products;

2. What are the items for the inspection of NSK bearing products, and why should they be tested?

3, NSK bearing goods before the quality inspection, what preparations need to be done, why do these preparations;

4. Under what conditions, the various inspection items of NSK bearing products are tested by what method and what instruments are used, and the results of the inspection must be within the tolerance range;

5. NSK bearing products are sometimes in large quantities and cannot be tested 100%. What kind of sampling plan should be used and how many quantities should be taken for inspection, in order to more comprehensively and reliably represent the quality of all commodity bearings, and test The results are then measured against what criteria to determine whether the goods are acceptable for approval or for non-conforming batches that should be rejected.

Acceptance inspections for NSK bearings can generally be divided into three categories, namely:

Routine inspection: A routine inspection of routine NSK bearings when they arrive.

Routine inspection: Inspect the NSK bearing and assembly related dimensional accuracy, rotation accuracy, bearing clearance and bearing residual strength.

Special inspection: Check the vibration quality, noise quality and other special requirements of the bearings of NSK bearings.

The above is the relevant content of the NSK bearing inspection and acceptance instructions. Knowing this, inspection and acceptance work will not be impossible, especially when encountering large quantities of products, there is no certain way, the work efficiency will inevitably be reduced, and it is not good to carry out . Therefore, if you are a big user of NSK bearings, then the above introduction is necessary to understand.
