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.

Where this bearing runs

Typical equipment and industries for this unit, from belt conveyors and bucket elevators to pulley shafts in mines, ports and cement plants.

Belt Conveyors 01 Belt Conveyors Belt conveyors use pillow block and flanged units on pulley and idler shafts, plus spherical roller bearings at the heavy-load positions. Units often run… See the application Bucket Elevators 02 Bucket Elevators Bucket elevators carry head and boot shafts on pillow block or flanged units, and the head shaft takes the full chain or belt load… See the application Mining, Cement & Aggregates 03 Mining, Cement & Aggregates Mines, quarries, aggregate producers and cement plants run long conveyor systems, crushers, screens and elevators in some of the dustiest and most heavily loaded… See the application Overhead Conveyors 04 Overhead Conveyors Overhead and trolley conveyors run on many small bearings in trolley wheels, chain guides and turn wheels, with flanged units on drive and take-up… See the application
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."
Emma Wilson Emma WilsonWilson Logistics Warehouse, Australia
