HSDG housing are available with felt-seal or combination of felt and labyrinth-seal. At face entry are machined area for an additional V-Ring to improve seal-arrangement.
Our HSDG pillow block housings, available in variants HSDG..C, HSDG..D, and HSDG..D, feature a re-lubricatable labyrinth seal with an additional felt seal. The HSDG.. and HSDG..H housings come equipped with a felt seal.
The split plummer block housings of the HSDG series are designed for the installation of spherical roller bearings. Shaft diameter: from 125 to 400 mm. The standard material is gray cast iron. Upon request, these housings can be supplied in a different material. The rolling bearings can be mounted with adapter sleeves, withdrawal sleeves, or directly on the shaft. The standard seal is made of felt. Other variants are also possible upon request. The bearing seat in the housing is machined to tolerance G7.
GGG40 is the most common alloy of ductile cast iron, characterized by a predominantly ferritic structure. This cast iron offers excellent machining properties along with high impact resistance, good electrical conductivity, and significant ductility and magnetic permeability. However, it is not weldable. Due to its high toughness, GGG40 is suitable for parts subjected to high forces, such as lifting arms, chain links, housings, brake shoes, and connecting rods.
