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.
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.
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.
