Functions of Bearing Housings

Please follow and like us:

The Bearing Housings are a one-piece unit, integrating shaft, housing and two bearings which dispenses with the need for two separate plummer blocks and bearings with adapter sleeve assemblies.  The unit is delivered assembled and pre-lubricated ready to install.  Most commonly used in fan applications, the units are also used in pumps, circular saws and transmissions.

Integrating modern deep-groove ball bearings guarantees high rotational accuracy and the units accommodate high levels of radial and thrust load with low friction and long grease life.  Both installation and operating costs are significantly reduced from a two housing installation.

Integral labyrinth sealing ensures cleanliness and allows operation at very high speeds (up to 15000 rpm dependant on size).  Sealed ball bearings can be fitted on request to dispense with the need to regrease.

Bearing combinations incorporating angular contact ball bearings or a ball bearing and cylindrical roller bearing can be fitted to accommodate extreme thrust and radial loads respectively.  Contact us to carry out a load analysis.

Bearing Housings

Shaft diameters are available from 18mm to 100mm with shaft extensions up to 60mm to suit most applications.

The Bearing Housings are a very high load variant of the familiar Bearing unit but now incorporating a high capacity spherical or self-aligning ball bearing fitted on adapter sleeves

The bearings provide a self-aligning capability under both static and dynamic loads, combined with high radial and axial load capacity.

The housings are fitted with felt seals as standard, alternatively double lip rubber seals can be provided.  The units are suitable for horizontal and vertical mounting with blank end or through shaft end cover combinations as required.

Designed to carry a modern high capacity spherical roller bearing, the unit is cast in one piece with separate end covers.  The housing is designed for strength and durability and is most commonly used in high energy and shock applications were a split plummer block unit will be limited in strength.

Design features include four bolt foot mounting, a strengthening rib around the centre of the housing and availability of cast steel or good quality grey iron.  Centre heights are generally interchangeable with split blocks for substitution purposes.

The range of housings accommodate shafts from 40mm to 150mm with any combination of through shaft or blank end cover and parallel or taper bore bearings.  The units can be set up as locating or floating assemblies as required.

The Bearing Housings is provided with felt seals as standard for operation with peripheral speeds of up to 4m/s.  For higher speeds and for extreme protection, labyrinth seals can be provided.
