Baldor Electric has introduced the Dodge Extreme Duty mounted ball bearing, which offers extended life in automation equipment in extreme industrial power-transmission applications.

These applications include aggregates, cement, paper, wood and metal processing.

The Dodge Extreme Duty bearings feature a sealing system and a ball retainer for superior protection and reduced maintenance.

These bearings, available in a variety of housing styles, use a 65-degree spacing for setscrews.

This design offers an optimum balance between locking force and inner ring stress.

The new sealing system, Quadguard, consists of a triple lip seal and a rubberised flinger.

The triple lip seal offers three points of contact, keeping the lubricant in and contaminants out.

This unique design maximises sealing with a minimal amount of drag.

The rubberised flinger is a moulded nitrile rubber component that is bonded to the flinger surface and provides an additional barrier to contaminants.

The rubber baffled design on the external surface of the flinger enhances the removal of liquid as it rotates, while grease chambers on the internal surface of the flinger prevent lubricant from exiting the bearing.

A new two-piece ball-retaining cage, Maxlife, creates a grease compartment around each of the rolling elements.

The compartments provide constant contact between ball and grease so an oil film always exists to prevent wear and minimise friction and heat.

The compartmental construction holds in the grease and prevents it from being washed out.

This exclusive design extends the life of the bearing and requires less frequent re-lubrication than standard designs.

For additional protection, the housings are machined with a groove to accept a snap-on polymer end-cover for exposed, rotating shafts.

These covers incorporate a drain hole to prevent moisture build-up.

Dodge Extreme Duty ball bearings also utilise the latest synthetic grease technology to provide lower operating temperatures and extend grease life and the interval between re-lubrication operations.

The Dodge Extreme Duty is available in a range of imperial sizes and metric sizes from 20 to 85mm.
