Product Description

 

Product Description

Reaction Bonded sic is sintered by adding the free silicon (content is less than 12%) into the reaction sintering sub-micron silicon carbide powder in 1500 ºC vacuum sintering furnace. Company produces silicon carbide material with excellent stability and wear resistance under high and low temperature, high speed, half dry friction working condition. The maximum overall sealing ring can be as big as 800 mm. So it is widely used in the bearing, petroleum, chemical, motors, ships and pump valve industries.

Floating seal consist of two same metal steel rings and two same rubber o rings.

Metal steel rings material are Alloy casting Iron (15Cr1Mo)

The working principle is a pair of metal rings supported by a pair of rubber rings to form a closed space with the cavity.

When running, the after-grinding seal surface of the two metal rings act in close coordination and sliding relatively.
