Seal control wire feature, used on HS7 HS split seal types Where downtime is critical and shaft removal is impractical, type HS all-rubber split seals are ideal. They are simply placed around the shaft and pushed into the seal bore, then held firmly by a cover plate, which compresses the split joint together. HS split seals perform best with grease or heavy lubricants as well as with light lubricants, placed no higher than the shaft centreline. Horizontal shafts are preferred with the split placed in the 12 o’clock position. HS split seals are available in a wide variety of types, styles and materials. HS6 HS6 is an all-rubber split seal with a single spring-loaded element and a Spring-Lock (page 199). HS6 features a separate loose spring and a positive spring connection. Generally, the spring connection is of the hook-and-eye type for shafts over 457 mm (18 in) and a threaded-type connection for smaller sizes. For proper fit, a cover plate is required. HS7 HS7 is an all-rubber split seal with a single spring-loaded element, which has both a Spring-Lock and a Spring-Kover (page 199). A control-wire spring connector is used to join the seal together (fig 72). HS7 does not have the high performance as other HS types, but it is the easiest one to install. The spring is completely enclosed and the connection is simply made by running the control wire into the center of the spring coil across the split (butt joint). Spring tension to hold the sealing lip on the shaft is built-in at the factory. For proper fit, a cover plate is required. Due to the unique design that permits easier installation, please note that a gap may occur at the joint even after the cover plate is installed. Special attention to place the gap at the 12 o’clock position during installation is necessary. gab.ru 208Берг АБ bergab@ya.ru Тел. (495)-228-06-21, факс (495) 22
gab.ru Берг АБ bergab@ya.ru Тел. (495)-228-06-21, Industrial факс shaft seals (495) 22 HS8 HS8 is an all-rubber split seal with a single spring-loaded element, Spring-Lock, Spring- Kover (page 199) and a positive spring connection. The spring is entirely enclosed except for a small portion on either side of the split. HS8 provides the most positive seal of all the split types and is the preferred design for use with lighter lubricant retention and water exclusion. HS8 performs best on horizontal shafts, but may also be used on vertical shafts. For proper fit, a cover plate is required. HS8 gab.ru Берг АБ bergab@ya.ru Тел. (495)-228-06-21, факс 209 (495) 22
