Description

These bearings are mounted into various shapes of pressed steel or grey cast iron housing, i.e. for heavier loads than pressed steel housing, Plumer blocks or flanged type-cast housing are appropriate. Deep groove ball bearings with an expanded inner ring and spherical outer ring are these bearings.
Via two threaded grub screws, these bearings are fastened on the shaft, other alternative tightening versions are also available such as eccentric self-locking collars, adapter covers, etc. or interference fit on the shaft. They are used where simplicity of design and assembly is needed in agricultural machinery, conveyor systems, construction machinery, etc. They are used to support the shaft with a tolerance of usually loose fir. In addition, broad clearance helps to compensate for misalignment & shaft deflection.
These bearings need no maintenance and are usually greased with the base grease of lithium soap. Such bearings will eliminate up to +5 degrees of static misalignment from the centre position. The speeds are kept low with rough shafts & loose fits. Relatively higher speeds can be achieved with tighter fits and more specifically machined shafts.
