SKF full double row cylindrical roller bearings can withstand axial load?

SKF full double row cylindrical roller bearings can withstand axial load? 2019 - 09 - Full of 18 SKF roller bearing is designed to carry heavy load. Under the same width, this kind of bearing and compared with cage bearing, can accommodate the most roller, high carrying capacity; But the permitted speed is far lower than the cylindrical roller bearing with maintain. Full of double row cylindrical roller bearing has four kinds of structure, three kinds of open architecture and 1 kind of sealing structure. All products are separated type design, outer ring with lubrication groove and oil hole, convenient lubrication. Type 1, type NNCL: NNCL bearing inner ring have 3 guard, outer rim. Outer ring of the central has a fixed link between the two sets of roller, can prevent roller bearing came out and keep one. NNCL type bearing can allow for thermal expansion or between shaft and bearing has certain axial displacement. The displacement is inside the bearing occurs, rather than, ring and shaft or outer ring and bearing seat. So bearing in the process of rotation, the friction did not increase. This type of bearing is suitable for used as a floating end bearing. Bearing outer ring is no guard, so the structure of products can bear radial load, unable to bear axial load. Type 2, NNCF type: NNCF bearing inner ring have 3 guard, outer ring with a guard. Can be a direction of axial positioning. Outer ring at the other end is equipped with a card, keep bearing. Snap ring is for bearing in the process of handling to prevent the scattered, unable to bear axial load. This kind of bearing can withstand high radial load and axial load of one-way, thus can realize shaft axial positioning in one direction. In another direction, used as a floating bearing. 3, NNC type: type NNC bearing inner ring and NNCL NNCF inner ring is the same, there are three guard. Bearing outer ring is split, and fixed by some parts, so can't carry axial load in single direction. Outer ring of two subdivision each take a guard, can be used as two directions of axial positioning. Bearing can withstand higher radial force and two-way axial force. 4, NNF type: also called solon bearing ( Outer ring with locking slot double row cylindrical roller bearings) 。 NNF NNF50 and 3194 size series, bearings with seals on both sides and is filled with grease. Inner ring is split with three guard, fixed by a snap ring, outer ring with a central guard, can make two direction axial positioning. Because there is a big gap between two rollers, thus bearing can inherit the overturning moment. NNF type bearing outer ring than the narrow circle of 1 mm, outer ring has two stop in cylindrical tank. So you can dispense inner ring with the gap between the adjacent components, such as in the application of sauron. This type of bearing rigidity is very good, can withstand high radial force and medium-sized two-way axial force. Sauron bearing polyurethane (on both sides AU） Contact sealing ring made of, can provide a good sealing effect. Bearing inner packing with lithium base grease, can be in - Use between 40 to + 80 ℃ temperature. This kind of bearing with seal, under certain conditions, is no maintenance. But in damp or a polluted environment, or in the medium to high speed running, do add lubrication bearings must be regularly, you can use the inner ring and outer ring lubrication hole for lubrication. Sealing ring can be removed from the bearing, bearing can be used as open type bearing. Hk united bearing focus bearing industry informationization service nearly 20 years, with many excellent bearing enterprise grows together, also witnessed China's bearing production technology from low to high development process. We will adhere to continue, the steadfast work, don't, don't give up, for the benign development of Chinese bearing industry do render some. Hk united bearing network bearing engineers, 2019. 03. 15
