Split plummer block housings SNLN 30 series

Features and benefits Fig. 2
SNLN 30 housings have the following features Reinforcement rib in the base
and benefits:
Stiff housing
The housing base is reinforced with ribs and
has extra material surrounding the holes for
the attachment bolts († fig. 2). This virtually
eliminates any distortion of the base and bear-
ing seat during tightening of the attachment
bolts.
Good heat dissipation
The centre cross reinforcement in the housing
base († fig. 3) 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.

Grease guiding system Centre cross for better heat dissipation
For more efficient relubrication from the side,
SNLN 30 housings have an integrated flange
that guides grease from the grease fitting
directly to the bearing († fig. 4). This feature
is available for housings up to and including
size 3038.
