    Copper-based bronze gleitlager non-oil lubricated bearings Composite Dry Bearings | VSB-11
     
    THIS product is tin bronze based powder inside and PTFE surfaced and filled with anti-high-temperature material. It is very safe and specially used in the place can’t stop for repair and can’t add oil because of high temperature.

     

     

    Six factors related to bearing life:

     

    • (1) [N/mm2] Load P
    • Larger loads and bearing service life is short; load fluctuation is bigger, larger influence on bearing life, bearing shorter life expectancy; whether, in any case, the maximum load can not be more than the theoretical maximum permissible value of the load. The load is equal to the actual working load divided by the area of the bearing, the formula is P=F/ (D*B).
    • (2) speed [m/s] V and PV
    • The working life of the bearing depends on the PV value, that is, the actual load [N/mm2] P and the sliding speed [m/s] V product, the smaller the PV value, the longer the bearing life.
    • (3) [oC] T
    • Bearing life also depends on the use of the bearing temperature, so in the design and selection of the relevant parts of the heat dissipation characteristics.
    • (4) surface roughness of grinding parts
    • The contact surface roughness of the parts of the bearing and the bearing of the bearing should be between Ra0.2~Ra0.8, and the bearing can not be sharp in the process of assembly and use.
    • (5) parts of the surface material of grinding, grinding parts surface rough degree is a factor influencing the service life of the shaft sleeve, generally a surface requirements reach less than or equal to 0.4 m Ka.
    • (6) other factors such as the design of the bearing seat, the lubrication condition, etc..

     

    Application

     

    This is widely used in steel metallurgy industry such as roller grooves of successive casting chines, cement grouting pumps and screw conveyers for cement. It can also be composed in steel housing or fabricated into flanged bushes which can move both in radial and in axial directions.

    STRUSTURE


     

    1. PTFE/fibre mixture thickness 0.01~0.03mm, provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.
    2. Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE/Fibre mixture.
    3. Bronze backing, provides exceptionally high load carrying capacity, excellent heat dissipation and very good corrosion resistance.
