Insert the roller bearings with their rollers between the inner and outer wheels; they are placed at right angles to each other. They can accept loads from all directions (such as axial, thrust or momentum loads). Appearance as the status quo touch; thus; the axis accepts the load and the possibility of elastic deformation is very small. In the interspersed roller bearing; because the cylindrical roller is perpendicular to each other through the distance holder on the V-shaped groove rolling surface of 90 ° Placement; therefore, a through-roller bearing can accept loads in all directions such as radial load, axial load and moment load.
Features: Insert roller bearing; inner ring or outer ring to be cut; after loading roller and distance holder; fixed with inserting roller collar; avoiding separation; therefore, device insertion roller collar The operation is simple. Because the rollers are placed in the insertion; therefore, only one set of interspersed roller collars can accept the load in all directions; compared with the traditional type; the rigidity is improved by 3~4 times. Together; the imported bearing fork roller bearings Because the inner ring or the outer ring of the inserted roller bearing is a two-cut structure; the bearing clearance can be adjusted; even if a preload is applied; a high-precision rotational motion can be obtained.
Uses: This type of bearing is widely used in industrial active robots, work machinery and medical equipment; when the demand is high rigidity, tight and high speed can still guarantee the accuracy.

Previous:The data of SKF bearing adherer affects the quality of bearing operation. The following is the hardness and relative wear rate of SKF bearing grinding oxide.
Reflective warning`s reflection part of the vest is the use of lattice micro-rhombus type refraction and high refractive index of glass beads back to the principle of reflection, through the post-processing of advanced processing technology made. It can reflect the distant light back to the light. Both in the day or night have a good retroreflective optical performance. Especially at night, it can play the same high visibility as the day. The use of this high-energy reflective material made of safety clothing, whether the wearer is in the distance, or in the light or scattered light interference, it can be relatively easy to be found by the night driver.
Reflective warning vests are made of high-visibility reflective material It can make the traffic police work smoothly in the night or special weather in order to reduce the rate of the casualties. it plays a special role in security especially in traffic engineering.When the motor vehicle fails, the driver needs to wear a reflective warning vest, and away from the faulty vehicle to prevent the occurrence of secondary accidents. This kind of reflective warning vest is mainly applicable to police, road officials, traffic commanders, road maintenance personnel, motorists, motorcycles and bicycles drivers, dark light workers and so on in one word, the local worker who needs to use light warning. Widely used in traffic engineering, shipbuilding industry, steel industry, machinery industry, oil industry, ambulance, parking lot, airport, traffic police and outdoor work or construction, plays an important role in good security warning .
When Car Reflective Vest use the aluminum lattice reflective material, not only in a small angle (from the reflective warning vest wearer far away), reflective brightness is high, even at a large angle (from the reflective warning vest wearer closer ), it still has a good reflective brightness, so that the locomotive driver earlier identified roadside vehicle side of the staff, as soon as possible to respond to effectively prevent the occurrence of secondary accidents.
According to reflective vest`s wearing [far distance discovers, near distance recognise" s character. It balances the big and small angle of optical performance. It has a large reflection angle.
