Ready Inspection and Easy Maintenance through Unique Bearing Construction

The ball and roller bearings can be greased while the motor is running. Waste grease is collected in a grease trap mounted on each end bracket. The used grease is removed with a single stroke of the discharge handle, simplifying inspection and maintenance. In frame sizes 500 or above, roller bearings at each end absorb radial load, and ball bearings at the drive end absorb thrust load. This assures stability and longer life.
Sleeve bearings employ efficient sealing between shaft and bearing to prevent lubricants from leaking either into the motor housing or outside the housing. The sleeve bearings are split into two halves. Removing the upper half exposes the bearing interior. Bracket removal is not required for inspection or maintenance.

HIGEN Motor Totally Enclosed Fan Cooled Vertical motors are designed to IEC dimension. As the apparatus is built with the main body that is totally enclosed, and cooled by a cooling fan on the opposite drive end, it allows direct installation of a counter apparatus on flange part by using it as a linkage axis bracket. It ensures a full performance of its advantage as motors for Machine tools, Pumps, Centrifuges etc. Often committed in dusty and humid environments.

DIMENSIONS in mm

Two types of the bearings are used for a motor.
Single-row cylindrical roller bearing are employed at drive end. Single-row deep-groove bearings are employed at opposite drive end. Motor is equipped with a short shaft extension for a direct-connected drive as standard.
