Sealed Spherical Bearings
Viton® is a registered trademark of DuPont Performance Elastomers.

Design
The relubricatable and maintenance-free rod ends and spherical bearings of sizes 8 to 30 can be provided with replaceable sealing sleeves to protect the bearing from coarse dirt, dust and splashing water. The elastic sealing sleeve is pulled on the outside over the specially extended and grooved bushing, and on the inside over a slip ring.
