SKF Cooper split roller bearings and bearing units

Flanged housings provide a simple means of mounting split roller bearings against a face or bulkhead perpendicular to the shaft. Designs and variants The housings are available in two designs: • round flange ( fig. 1 ) • square flange ( fig. 2 ) They can be used for both the locating (designation suffix GR) and non-locating (designation suffix EX) bearing positions. Alternative designs, e.g. an axially com- pact housing design with a flat flange ( fig. 3 ), are available on request. Housing materials • grey cast iron (grade EN-GJL-250 in accordance with BS EN 1561), as standard for housings with a round flange except when used with split tapered roller bear- ings where ductile iron (see below) is used • ductile iron (grade EN-GJS-400/18 in accordance with BS EN 1563), as standard for housings with a square flange Alternative materials are available. Please contact SKF for more information. Permissible misalignment Under constant or slowly changing alignment conditions, there is a permissible misalignment up to 2,5 ° without compromising sealing capability.
