CH440 / CS440 Cone Crusher Main Shaft Hydraulic Seal Backup Ring is an aftermarket replacement component designed for the hydraulic sealing assembly of CH440 and CS440 cone crushers. Installed together with an O-ring, the backup ring helps prevent seal extrusion under high hydraulic pressure and protects the O-ring from damage.
Manufactured from PTFE (Polytetrafluoroethylene), the backup ring provides excellent wear resistance and reliable performance under demanding hydraulic operating conditions. It is designed to maintain proper support around the O-ring and help ensure reliable sealing system performance.
As an aftermarket replacement part, CH440 / CS440 hydraulic seal backup rings can be supplied in specified sizes and manufactured according to equipment specifications, technical drawings, or customer-provided samples.
CH440 / CS440 Cone Crusher Main Shaft Hydraulic Seal Backup Ring is a PTFE anti-extrusion component used together with an O-ring in the hydraulic sealing assembly of cone crushers. Its primary function is to support and protect the O-ring under high hydraulic pressure.
During hydraulic operation, high pressure can cause an O-ring to deform or become extruded into the clearance between mating components. The PTFE Backup Ring helps prevent this extrusion and reduces the risk of seal damage, contributing to reliable performance of the hydraulic sealing system.
As an aftermarket replacement part, the CH440 / CS440 Main Shaft Hydraulic Seal Backup Ring can be supplied in specified sizes and manufactured according to equipment specifications, technical drawings, or customer-provided samples. It is suitable for maintenance and replacement applications in mining, quarrying, and aggregate crushing operations.
