Baldor has announced that its Munich facility is carrying stocks of component parts for Dodge HFO oil-lubricated spherical roller bearings, backed by a fast-turnaround housing-assembly service.

These bearings, usually paired with split plummer block housings, are used extensively in the air-handling industry.

The bearings and housings are designed for applications where reliability and long inter-maintenance intervals are key criteria, such as industrial fans and blowers.

The bearings and housings are also ideal for critical machinery such as emergency generators.

By being able to supply custom-assembled housed bearings direct from stock held in Munich, Baldor expects to reduce lead times on orders from European customers to a matter of days, even for complex parts that need to be modified.

Mike Shea, international sales director for Dodge Mounted Bearings, said: ‘Baldor’s Munich facility now carries a very wide range of Dodge HFO housings and spherical roller bearings, spanning shaft diameters from 75 to 240mm.’ Dodge HFO split plummer block bearing housings are designed for dynamic oil lubrication; the bearing sits on a support above a large – and physically separate – oil sump, and the oil is pulled from the sump to the bearing by a rotating oil conveying ring, to automatically lubricate the bearing during operation.

The housings incorporate an oil drain to allow the oil to return to the sump, which transfers heat away from the bearing and into the sump, where it is removed by convection or sump-cooling coils – as well as an oil-level gauge for ease of maintenance.

The housings are supplied with labyrinth seals to ensure lubricating oil retention and to prevent the ingress of contaminants; for applications involving particularly dirty environments, grease can be pumped between the housing and the seals to provide extra protection.

All Dodge HFO bearing housings feature split plummer blocks and bolt-on end covers to facilitate bearing removal and to minimise the amount of work space required.

The housings only require the shaft to be lifted enough to remove the load before the bearing can be removed, which simplifies maintenance and repair and helps reduce machine downtime.

As standard, Dodge HFO bearing housings are manufactured from grey cast iron, but for especially demanding applications, various models are also available in spheroidal ductile iron, which has a higher tensile strength and a higher modulus of elasticity.

All models are supplied configured for non-expansion (F) mode – whereby spacer rings in the housing hold the bearing in a fixed position – but can easily be reconfigured by customers for expansion (L) mode, simply by removing the spacer rings, which then allows the bearing to float with shaft expansion.

If required, Baldor can supply HFO bearing housings modified to allow greater axial movement than standard units, to accommodate greater shaft expansion.

The company can also carry out a number of other modifications on request, including the provision of extra pre-drilled holes for temperature and vibration sensors and the fitting of copper cooling coils to allow water cooling of the oil sump.
