The IB outer spherical ball bearing consists of a wide inner ring deep groove ball bearing with a double-sided seal and a spherical outer cross section and a bearing seat (cast iron seat or steel plate stamping seat). The typical layout is shown in the figure below. The bearing unit has a compact layout; it has the function of active self-aligning; the equipment is convenient to protect; it has perfect sealing equipment and reliable sealing function; it is suitable for harsh working environment. It is widely used in agricultural machinery, construction machinery, textile machinery, food Processing Machinery. And conveyor belt systems and other categories.
2. Features of spherical ball bearing with seat â– The outer diameter of the bearing with active self-aligning function and the inner diameter of the bearing seat are spherical cooperation; there is active centering function between the two; it can compensate the axis misalignment due to equipment errors and the bottom surface of the equipment Deformation.
â– The load can be large because the internal layout of the outer spherical ball bearing is the same as that of the 6200 and 6300 series deep groove ball bearings; therefore, the IB spherical outer spherical ball bearing can not only accept radial load; but also can accept large axial load. Together with the bearing The work noise is small.
â– The long-life spherical ball bearing is usually used in harsh working environments such as dirt, dust, moisture and high temperature; the smooth grease inside the bearing will change in a short period of time. Therefore, the demand is at the right time. The outer spherical ball bearing is greased from the head; the fresh smooth grease replaces the smoothed grease. The IB cast iron outer spherical ball bearing has a grease nipple; it can be smooth from the head; it ensures perfect function and length in any working environment. Life expectancy.
â– Excellent sealing function The outer spherical ball bearing has heat-resisting, oil-proof rubber sealing ring and steel dustproof cover on both sides. The dust cover device rotates together with the inner ring on the outer diameter of the inner ring of the bearing; it can effectively prevent External foreign matter enters the inside of the bearing; and can resist the external pressure to protect the bearing; the combined seal composed of the sealing ring and the dust cover can block the dirt, dust and moisture from entering the inside of the bearing; together, it can hinder the smooth grease leakage inside the bearing. The bearing can also adhere to the perfect working function under the harsh working environment.
â– Consolidated bearing seat cast iron seat is the whole seat layout; the bearing seat is extremely rigid; the bearing is prevented from being deformed during the equipment; the bearing seat is durable in any working condition.
â– The bearing can be easily locked on the shaft. There are three ways to lock the bearing on the shaft; the common method is to lock the two setscrews on the extended end of the inner ring; also use the adapter sleeve or the painful sleeve lock. Tight. These three methods can easily lock the bearing on the shaft.
â– The inner ring of the bearing is specially heat treated. Some of the inner ring channel and its surrounding hardened are hardened. Normally, the inner ring end of the set screw of the equipment is tempered by the high temperature part to maintain the resistance and impact resistance. After the high-temperature tempering around the screw hole; the bearing obtains a better function; it can prevent the screw from being loosened during the bearing operation time; the screw is tightened very tightly and will not cause the inner ring to burst.
â– The common bearing bearing outer ring with anti-rotation of the outer ring is equipped with a common stop pin (ball); the stop pin allows the bearing to be actively aligned; it can prevent the outer ring from rotating; the bearing has a longer service life.
â– Bearings and housings can be completely exchanged. Bearings and housings are finely machined; bearings and housings can be completely exchanged; bearings can be easily replaced at any time.
â– Simple equipment The spherical ball bearing has been pre-written with satisfactory high-quality smooth grease; the spherical ball bearing with the seat can be directly mounted on the shaft. Therefore, harmful substances can be prevented from entering the bearing during the bearing unit of the equipment.
3. Spherical ball bearings with smooth seat are usually not protected; high-quality smooth grease filled in the bearing can usually satisfy the service life of the bearing. However, if the working environment is bad, the bearing runs at high speed or the working temperature is above 70 °C. Time; it is necessary to make up for the smooth grease of the bearing. The IB outer spherical ball bearing has a smooth layout, and the smooth grease is written by the oil gun into the oil nozzle of the bearing seat. The oil groove and the oil hole on the outer ring of the bearing enter the bearing interior.
4. The adjustable spherical outer spherical ball bearing can accept the initial viewpoint error of not more than ±5°. However, if it needs to make up for the smooth grease, the initial angular error is only ±2.5°; otherwise the oil hole on the outer ring Will be covered.
5. The load of the outer spherical ball bearing can be the same as that of the deep groove ball bearing; the calculation method of the equivalent load is the same as that of the deep groove ball bearing (see page 4). The axial load can be determined by the inner ring and the bearing consolidation. Degree; usually should not be greater than 20% of its additional load; when the axial load is large; the consolidation equipment should be added on the shaft; such as the shoulder.
6. When the equipment tutoring equipment has a spherical outer ball bearing; put the bearing on the shaft; first fix the bearing seat firmly on the bearing surface; then fasten the bearing to the shaft. The fastening method of the bearing and the shaft Yes: For outer spherical ball bearings with set screws; use a hexagon socket screw wrench to lock the two setscrews on the wide inner ring of the bearing in place. For outer spherical ball bearings with a painful tightening sleeve; On the upper pain platform of the inner ring of the bearing; tighten the painful sleeve along the direction of rotation of the shaft; then tighten the set screw on the painful sleeve with a hexagon socket screw.
