Standard housing design
PD two-bearing housings are non-split housings with two bearing seats (fig. 1). They consist of a housing body and two covers that are bolted to the body with either four or six bolts. The housings have four holes drilled into the feet for attachment bolts.
PD housings are available in three series, each similar in their external design, but accommodating different bearing arrangements:
- PDN series, for normal radial and axial loads
- PDP series, for predominant or alternating axial loads
PDR series, for heavy radial and normal axial loads
