Before You Order

Check these three points first

Shaft size alone does not guarantee a fit. These three checks prevent units that arrive and do not match the existing frame.

  • Shaft diameter

    Measure the actual shaft, not the old part number. Note the locking type: set screw, eccentric collar or adapter sleeve.

  • Bolt spacing & mounting

    Pillow block, flanged or take-up frame. Give the bolt centre distance and centre height so the unit drops into the existing frame.

  • Operating environment

    Dust, water, washdown, load and running hours decide the seal design and bearing series.

Field Results

What maintenance teams report

"We had a repeated failure on a take-up bearing position. Their engineer suggested a heavier unit with a triple-lip seal. We installed it three months ago and it is still running cool. They also supplied all the other bearings we needed for the shutdown."
Robert Johnson Robert JohnsonJohnson Grain Terminal, USA
"Identifying an old flanged bearing unit on an overhead conveyor was tricky. We sent photos and bolt spacing measurements, and they matched the exact unit within hours. They also supplied the matching deep groove bearings for the drive motor at the same time."
