Features and benefits

SNL plummer block housings in the 30, 31 and 32 series have the following features and benefits:

Stiff housing

The housing base is reinforced with ribs and has extra material surrounding the holes for the attachment bolts (fig. 1). This virtually eliminates any distortion of the base and bearing seat during tightening of the attachment bolts.

Good heat dissipation

The centre cross reinforcement in the housing base (fig. 2) increases the contact area between the housing base and the support surface to improve the heat flow from the bearing outer ring to the support surface.

Caps and bases individually marked

The housing cap and base are matched during manufacture and are not interchangeable with the caps and bases of other housings. To prevent any mismatches, a unique serial number is marked on both the housing cap and the base (fig. 3).

Dimples to locate accessories

Dimples cast into the housing cap indicate where grease fittings and condition monitoring sensors can be mounted for maximum effectiveness (fig. 4).

Simple mounting

To simplify mounting and make alignment more accurate, lines indicating the centre of the bearing seat and housing bore axis are cast into the housing base. Dimples indicate the position for dowel pins (fig. 5). Mounting instructions are supplied with each seal pack. The housings have two eyebolts on the cap for safe and easy handling.
