STL drum take-up housings
Split take-up housings for conveyor drums, in GS 45 cast steel with a double labyrinth.
STL housings are split and made from GS 45 cast steel; spheroidal or grey iron on request. They take spherical roller bearings with a cylindrical bore or on an adapter sleeve.
Depending on requirements they are supplied as locating or floating bearings.
Sealing is a double labyrinth at both ends, with grease lubrication. Two grease holes sit midway between the bearings; the labyrinths can have separate holes.
