FNL flanged housings

FNL flanged housings are well-proven machine parts that provide simple, reliable housing in applications without horizontal frames. They enable the full service life potential of the incorporated bearings to be exploited with less need for maintenance.

Features and benefits

Simple mounting

Lines cast into the housing flange indicate the centre of the housing bore. Dimples indicate the position for dowel pins (fig. 1).

Grease guiding system

An integrated flange guides grease from the grease fitting into the bearing (fig. 2).

Low friction seals

A low friction, double-lip seal on each side of the housing keeps grease in and contaminants out (fig. 3). These seals allow rotational speeds twice that of traditional felt seals.

Two predrilled holes for relubrication

The centered hole enables relubrication via a lubrication feature in the bearing. The offset hole enables relubrication from the side.
