Sealing Split Seals

Sealing Split Seals

Split seals are used to reduce downtime in replacing seals especially during shut down time, without removing heavy couplings or parts. Split seals should be used in applications such as bearing mounted on shafts, gear box couplings, fly wheels of various equipment in various industries.



Split seals Installation instructions

1.Where applicable, insert the spring in the Springlock and position the spring connection, so that it is displaced with regard to the seal joint. Put the seal in the correct position on the shaft.


2.Lightly coat both the seal and counterface surface with a lubricant, preferably the same that will be used in the application.

3.Close the spring connector to join the 2 ends of the garter spring. For threaded connectors, back-wind the spring a couple of turns before the ends are brought together and allowed to thread into each other. When using a hookand-eye connector, draw the ends of the spring together and insert the hook into the eye. Take care not to over-stretch the spring in the process.

4.Position the seal joint on the shaft so that it is at the 12 o’clock position and push both ends of the joint into the housing bore. Do not push only one joint and then work around the shaft as this will create an excess length, making installation dificult or impossible.


5.Continue at the 3 and 9 o’clock positions, push the rest of the seal into position and inish simultaneously at the 6 and 12 o’clock positions. Use a small block of wood if needed to push the seal in the housing bore until it contacts the housing shoulder.

6.Check the seal condition, particularly at the joint, to make sure that it has been positioned properly. Install the cover plate on the housing face. Tighten the bolts evenly until
the cover plate abuts the housing face.
