Skf bearing products deep groove ball bearings commonly used suffix

    The standard products provided by skf have various types of skf bearings of 20,000. In addition to rolling skf bearings, skf group also manufactures linear bearings, plain bearings, bearing housings, ball and roller screws, textile machinery parts, and retaining rings. , machine tools and various precision mechanical parts. With extensive experience in these areas, he has the knowledge and expertise to develop, manufacture and apply a wide range of advanced engineering products.
    The small ones are only 0.003 grams of miniature bearings, roughly 34 tons of giant skf bearings. In addition, skf also provides a number of bearing repair tools, grease and bearing testing equipment, in order to make skf imported bearing users get higher efficiency and achieve worry-free operation.
    Skf bearing featured product explorer series bearing, this series of skf bearings has better performance and longer life than any brand on the market. It has been outstanding in design and use. It is the top scientist of skf engineering and research center in the Netherlands. After years of careful research by the engineering team, the skf explorer bearing shell is identified by the EXPLORER logo on the outer ring side of the bearing and the EXPLORER logo on the box, but the product number remains unchanged.
    Skf bearing products deep groove ball bearings commonly used suffix:
    CN: Normal Group Radial Clearance: Usually used only in combination with the following letters to indicate a narrow or offset range of play. H: The narrowed clearance range is equivalent to the upper half of the original clearance range. L: The narrowed clearance range is equivalent to the lower half of the original clearance range. The clearance range of the P offset is equivalent to the composition of the upper half of the original clearance range and the lower half of the next set of clearance ranges.
    The above letters are also applicable to the following combinations of gaps into corresponding meanings: C2, C3, C4, C5, for example C2 C2: radial clearance is smaller than the normal group. C3: The radial ranger is larger than the normal group. C4: Radial clearance is greater than C3. C5: Radial clearance is greater than C4.

SKF bearing storage method

       Learn from SKF authorized dealers how to store SKF bearings
       1: The storage location must be protected from moisture because the bearing will rust once it has passed through the tide.
       2: SKF carton packaging should be placed on a certain specification shelf to facilitate the search and restocking
       3: When transporting large bearings, use tools and forklifts to handle the goods.
       4: Try not to suppress some plastic-packed goods. Because after all, it is plastic
       5: Do not mix the models because the grease inside the different models is different.
       6: Regular maintenance, such as cleaning some anti-rust oil frequently
       7: Put some of the outer packaging of the bearing as much as possible with a cloth to prevent the bearing from entering the dust.
       8: Some precision spindle bearings must be handled with care.
       9: SKF packaging should not be squeezed to prevent the box from being broken when the customer will be disgusted.
       10: Follow the instructions during maintenance

How to prevent precision imported bearings from rusting

Corrosion occurs, which not only affects the accuracy and surface roughness, but also reduces the service life, even scrapped and cannot be used.

Bearing anti-rust work is an important task, especially the rust prevention between processes, like the bearing in the heat treatment workshop after pickling, cleaning, grinding, there are many processes. When the product is not produced by running water, it is stored in the intermediate tank once it is processed sequentially, so the bearing rings stored between the processes must be rust-proof.

The conventional anti-rust oil anti-rust method similar to rust-proof paint and the methods for preventing rust between the bearing processes are generally the following:

1. Dip in the rustproof tank
The bearing ring is immersed in an aqueous solution of 5% sodium nitrite and 0.6% sodium carbonate. The anti-rust effect is good, but many rust-proof tanks and other equipment occupy a large amount of space, and management is not convenient.

2. Dip coating of concentrated sodium nitrite solution
After washing the product, it is immersed in a solution containing 15%-20% sodium nitrite and 0.6% sodium carbonate, and then stacked. In this way, the rust-preventing period is short, generally only 7-14 days, and in the rainy season, due to the wet weather, it can only be re-treated after 2-3 days, which requires labor and money.

3. Oiling
Apply anti-rust oil like anti-rust paint like finished product. This method must be cleaned before the next step is performed, which is troublesome.

Some common terms for rolling bearings

Some common terms and definitions of rolling bearings, mainly rolling bearing generals, radial bearings, thrust bearings, ball bearings, roller bearings, etc.:
(1) General theory of rolling bearings:
1. Rolling bearing: A bearing that performs rolling motion between a load bearing and a moving part relative to each other, which includes a raceway part and a rolling body set with or without isolation or guides, which can be used to bear radial, axial or radial Combined load with the axial direction;
2. Single row bearing: a rolling bearing with a row of rolling elements;
3. Double row bearing: a rolling bearing with two rows of rolling elements;
4. Multi-row bearing: Rolling bearing with more than two rows, bearing rolling bearing in the same direction, it is best to indicate the number of columns and bearing type, for example: "four-row radial cylindrical roller bearing";
5. Full complement rolling element bearing: bearing without cage, the total gap between the circumferential direction of each row of rolling elements is smaller than the diameter of the rolling element and as small as possible, so that the bearing has good performance;
6. Angular contact bearing: a rolling bearing with a nominal contact angle greater than 0° and less than 90°;
7. Self-aligning bearing: a raceway is a spherical shape, which can adapt to the angular deviation and angular movement between the two raceway shaft lines;
8. Separable bearing: a rolling bearing with separable components;
9. Non-separable bearing: After the final assembly, the bearing ring can not be freely separated rolling bearing;
Note: For bearings with different parts to separate parts, for example, ball bearings with double half rings (02, 01, 08) do not specify abbreviated terminology;
10. Inch bearings: Rolling bearings in the original design when the dimensions and tolerances are expressed in English units;
11. Open bearing: rolling bearing without dust cover and sealing ring;
12. Sealing ring bearing: a rolling bearing with a sealing ring on one or both sides;
13. Dust cover bearing:
Rolling bearing with dust cover on one or both sides.
14. Closed bearing: a rolling bearing with one or two sealing rings, one or two dust caps and a sealing ring and a dust cover;
