Key Features & Applications
Four-bolt square flanged units are recommended for industrial applications where normal loads are applicable.
These assembled units come with ready mounting position, using four bolts through the flange.
Bolt-hole distance and shaft center location are interchangeable with competitive units.
The insert ball bearing unit combined the spherical outer surface of the bearing match the concave shaped in inside diameter of the housing which gives the unit unique self-aligning ability.
These flange units are pre lubricated, which can be easy to install on immediate necessity.
Designed with grease nipple provision for re- lubrication
lts special bonded seal design is appropriate for wet or dull environments.
The flange unit can be fitted to machines with four- bolts.
Suitable for wall mounting surface, for example the side of machinery.
Special designed housing to replace the bearing comfortably.
