Tech Tips
The Importance of Proper Lubrication – and
Mounting – of Motors with Rigid Sleeve Bearings
Babbitt-lined, steel-backed sleeve bearings are quiet, long life bearings capable of operating heavier direct drive air moving loads. They are most frequently used in motors with diameters exceeding 5". They’re also very popular in 48 Frame motors because of their long life and hefty load carrying capacity. These bearings are pressed into a die-cast end shield for maximum support and heat dissipation. Due to
the solid contact with the end shield, they dissipate heat better than
self-aligning bearings.In rigid bearing systems, oil is transferred from the oil reservoir to the shaft surface by a felt wick that
extends through a window in the bearing, typically known as a wick
window. The wick allows the oil to flow from the reservoir, through the wick, to the shaft surface. As the shaft rotates, a lubricating film is developed between the shaft and bearing.The system also includes an oil slinger (rubber washer) to return any oil that travels down the shaft to the reservoir. The slinger is ineffective
at speeds below 500 RPM because oil can seep out between the shaft
and bearing, causing severe loss of lubricant. Wind milling (which happens, for example, when a warehouse side wall ventilator, while shut off, slowly spins due to outside wind blowing through it) may actually deplete the oil from a bearing system in a short
period of time. Rigid sleeve bearings also introduce one limit to “All Angle” mounting. The surface area of the bearing is reduced
at the window location, which also reduces the load capacity in this
quadrant of the bearing. Therefore,extreme care should be taken to avoid loading the motor in the direction of the wick window. This includes mounting the motor with the windows in the downward position in a shaft horizontal fan unit. Doing so can reduce the life of the motor significantly. The wick window is located at the
re-oiling location. If the motor does not include an oil hole or removable plug, the wick window is located atthe end of the widest rib in the motor end bracket. The general rule of thumb is to be certain to mount the motor in the unit so the oil hole or widest rib is always within 60 degrees of straight up.
