Bearing application
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. |

1. Dimensions of the shaft extension key and keyway are based on KS (Korean Standard) B 1311 "Sunk keys and Their Corresponding Keyways."Shaft extension key is furnished
2. Tolerances on dimension LB of flange diameter and S of shaft extension diameter are based on KS B 0401 "Limits and Fits for Engineering."
3. Approximate motor weights are of maximum motors.
4. Terminal box can be turned to one of four positions, 90 degrees apart to provide easy entrance of the power leads. |
