15th November 2010 - DODGE® developed a new range of large-bore pillow block bearings, initially with SAF dimensions, that feature integral hydraulically-assisted, adapter-mounted installation and removal systems.
These bearings are designed to reduce the total cost of ownership, are factory assembled, sealed and lubricated. The entire inner units are replaceable, meaning that another factory assembled, sealed and lubricated unit can be installed having never been subjected to environmental contamination.
This new range of hydraulically mounted bearings covers the size range from 150 to 400mm. This now means that the Baldor range of easy mount/dismount bearings span from 17mm to 400mm across three ranges of bearings; the Grip Tight, the ISN and now the Hydraulic ISAF range.
A major cause of bearing failure is due to contamination, either during installation or in service (especially when under misalignment conditions). The DODGE® Hydraulic ISAF solution has a double seal that is effective even under misalignment conditions.
The inner unit has a triple lip seal and the housing has a grease purged labyrinth design or optional closed end cover. This multiple seal design keeps out the contamination, allowing the bearing to achieve its maximum life.
"At Baldor, we would like the market to stop considering bearings as a commodity and start to think of mounted bearings as an asset", said Daniel Vera, Managing Director of Baldor Australia. "For too long, the customer has been forced to expend considerable time in the installation, maintenance and removal of mounted bearings. This generally happens in dirty environments and this creates further problems leading to shorter than expected life. Our new Hydraulic ISAF bearing overcomes these issues in a unitised, compact package".
