Cast iron plummer block housings
- high levels of contamination
- high speeds
- high temperatures
- relatively heavy loads
SY(J) series (fig. 1, fig. 2)
→ cast oblong bolt holes
→ similar to SY series, but with a lower centre height H1
→ similar to SY series, but accommodates a larger bearing for a given shaft size, resulting in a higher load carrying capacity
SYF(J) series (short base, fig. 3, fig. 4)
→ threaded holes in the support base
To protect the bearing arrangement at the end of a shaft, and to avoid the possibility of an accident caused by an exposed shaft end, cast iron plummer block housings in the SY .. M series are able to accommodate ECY series end covers (fig. 5). End covers are accessories and must be ordered separately. The designations together with the distance A5 that the end cover protrudes from the housing (fig. 6) are listed in the product tables (→ Plummer block housings for insert bearings, Ball bearing plummer block units).
The complete assortment of end covers for ball bearing housings and units is listed the product table.
