flexibox,
These are equivalent to Crane type 21 or type 1 seals. The mating rings are glued to the rubber bellows to make installation easier by keeping the ring attached to the rest of the seal. I'm not sure what the proper term is for a glue that doesn't harden is. This glue remains tacky and...
We have been having trouble keeping single spring seal faces attached to the rubber bellows, especially the tungsten carbides on shaft sizes over 2".
Can anyone please suggest a product that would work for us?
Thanks, Bill
To my knowledge that has always been a US Seal PS2155 with a seat thickness of .437". In the most recent US Seal catalog it is now crossed to a VG-110608V with a seat thickness of .345".
Does anyone know why that changed and if it would be unwise to use any left over PS2155s?
