CS-8000
The CS style is the same as the CE-8000 except that it has an exposed metal exterior and metal O.D. for a heavy press fit and easy, accurate installation.
CE-8000
The 8000 series seals are narrower than the 7000 series seals. They are used in applications where a snap ring is required to positively retain the bearing cup in the housing. This series is used in crown and traveling blocks, and in mine-car wheels. Clark recommends all seals installed in damaged housings be bonded into the housing with an industrial adhesive.
