Angular touch ball bearings can accept both radial and axial loads; they can work at higher speeds. The larger the touch angle is, the higher the axial load is. The high precision and high speed bearings usually take a 15 degree touch angle. Under the force effect; the touch angle will increase. The bearing is mainly used on the machine tool spindle. Usually; the outer ring of this bearing has a lock; therefore, the annular groove thus formed cannot be sealed; so that many are used on the machine tool spindle The angular touch ball bearing cannot be filled with smooth grease like other bearings used on another mainframe. If it is equipped with a set of auxiliary smoothing system; it is necessary to add cost; and the machine layout is more messy. The advanced method is to use a new type. The groove of the groove is embedded in the bearing; the depth of the groove is slightly shallower than that of the gauge bearing; and it is just suitable for the intersection; it fills the gap left by the flange of the outer ring. Participating in this seal can block the smooth grease. It leaks from both ends of the bearing; it can also block the intrusion of dirt from the two ends of the bearing.
Because the inner and outer races of the angular touch ball bearing can have relative displacement on the horizontal axis; therefore, the radial load and the axial load can be accepted together; that is, the single row angular touch ball bearing can only accept the uniaxial axial load; The method of selecting a pair of devices is required.

AASHTO M247 Glass Beads,we mainly manufactures Drop-on Glass Beads, prermix Glass Beads ,Blasting Glass Beads, Grinding Glass Beads and other reflective glass beads. We can produce micro glass beads for road marking based on the standard of EN1423/1424, AASHTO M247, BS6088, JIS R3301,KS etc. these differents standards can meet different market for the road marking lines and traffic signs.

Reflective Standard Type 1 Glass Beads,AASHTO Tpye 1, Glass Beads, Sand like texture. Same glass beads used on interstate, highway and local traffic lines.Makes paint reflective. Beads are sprinkled on top of the wet while it is still wet at a ratio of 6 pound beads per gallon of paint. roundness >= 80%. Refractive index is >= 1.51.

Retroreflective highway signs and lane markers use special kinds of paints and materials. Most retroreflective paints and other pavement marking materials (PMM) contain many thousands of glass beads per square foot that are bonded to the highway with a strong binder. Instead of scattering light, as normal paints do, retroreflective paints containing glass beads turn the light around and send it back in the direction of your headlights.
