1, the product structure
IB with Block spherical ball bearings sealed by a double-sided outer wide inner ring with spherical outer cross-section deep groove ball bearings and a bearing (cast iron or steel stamping Block) composed of two parts. Typical structure shown below. The bearing unit is compact, with self-aligning, installation and maintenance convenience, perfect seals, sealing performance and reliable, adapted to the harsh working environment. Widely used in the field of agricultural machinery, construction machinery, textile machinery, food processing machinery and conveyor systems, etc..
2, seat belt, spherical ball bearings characteristics
■ with self-aligning
Bearing diameter and bearing inner diameter of the spherical co-ordination between the two self-aligning function can compensate for the axis do not coincide and installation of the underside of the deformation due to installation errors.
■ load capacity
The internal structure of spherical ball bearings 6200 and 6300 series deep groove ball bearings, thus the IB LNSERTED ball bearings can not only withstand a radial load, and can withstand greater axial load. Bearing Noise at Work.
■ long service life
Seat belt, spherical ball bearings are commonly used in harsh operating environments such as soil, dust, moisture and high temperature, the deterioration of the bearings inside the grease in the short term. Thus, within the appropriate time interval, pillow block, spherical ball bearings, the grease re-lubrication, and instead has gone off the grease with fresh grease. IB with cast iron, spherical ball bearings with a grease nipple can be re-lubrication to ensure perfect performance and long life in any work environment.
■ excellent sealing performance
The spherical ball bearings on both sides with a heat-resistant, oil resistant rubber seals and the combination of steel dust cover seal. Dust cover assembly and the inner ring on the outer diameter of the bearing inner ring with rotating external and can effectively prevent the entry of foreign matter inside the bearing, and resistance to external pressure to protect the bearing, the combination of this ring and dust cover seal to prevent dirt, dust, moisture into the bearing, but also inhibit the bearings inside the grease leakage. So that the bearing can maintain perfect performance of the work under poor working conditions.
■ solid bearing
Cast iron seat for the whole seat structure, bearing rigid superb, to prevent the bearing deformation during assembly, and are durable in any conditions bearing.
■ bearings can easily lock the shaft
Bearing lock the shaft in three ways commonly used method is the elongation end of the locking inner upper two set screws, can also use the adapter sleeve or eccentric sleeve locking. These three methods can be bearing easily lock the shaft.
■ bearing inner ring to a special heat treatment
The inner channel and the surrounding hardened part of the normal quenching, the assembly set screws of the inner elongation end after high temperature tempering while maintaining the toughness and impact resistance. The inner ring around the screw holes on the local high-temperature tempering, the bearings for better performance, prevents the screw in the bearing during the Song off, screw very tight and will not cause the inner ring burst.
■ has a unique design to prevent the outer ring rotates
The bearing outer ring is equipped with a unique stop pin (ball), the retaining pin to allow the bearing self-aligning, but also to prevent the outer ring rotates, so that the longer bearing life.
■ bearing and the bearing can be completely interchangeable
The bearings and housings are precision machined, bearings and bearing housings can be completely interchangeable at any time can easily replace the bearings.
■ Easy installation
The spherical ball bearings are pre-injected enough high-quality grease will LNSERTED ball bearings mounted directly on the shaft can. Thus avoiding harmful substances into the bearings inside the process of installing the bearing unit.
3, lubrication
The LNSERTED ball bearings usually are not required to maintain and fill in the quality grease within the bearing assembly generally able to meet the bearing period of use. However, if the working environment, bearing high-speed running or operating temperature above 70 ℃, bearing complement grease is required. IB with Block spherical ball bearings lubricated grease is injected into the bearing housing oil gun nozzle. Through the tank and the hole on the bearing outer ring into the bearing.
4, adjustable Mind
LNSERTED ball bearings can withstand greater than the initial angle of error of ± 5 °. But For supplementary grease, the initial angle error of only ± 2.5 °, otherwise the hole will be on the outer cover.
5, load capacity
Spherical ball bearings, deep groove ball bearings, load capacity and its equivalent load calculation methods are the same as deep groove ball bearings (see Section 4). The axial load capacity depends on the inner ring and the bearing strength of, under normal circumstances should not be greater than the rated load of 20%, increase in the axis when the axial load, rugged devices, such as the shaft shoulder.
6, the installation instructions
When installing the seat belt, spherical ball bearings, bearing to the shaft, the first bearing is firmly fixed to the supporting surface, and then bearing secured to the shaft can. Bearing and shaft of the fastening method is: spherical ball bearings with set screws, socket head cap screw wrench, two tight bearings wide inner ring set screw lock in place. Spherical ball bearings with eccentric fastening sets, eccentric eccentric stage of the condom on the bearing inner ring, along the axis of rotation direction tighten the eccentric sleeve, then socket head cap screw wrench to tighten the set screws with eccentric sleeve.
