S-type bearings and clamping frame bearings
S-type bearing are housing bearings with two slots, which allows them to be axially displaced (loaded). Clamping frame bearings are ready-to-mount clamping frames made of steel sheet for easy installation and already contain a s-type bearing in suitable dimensions.
Note: Bearing inserts with an eccentric ring are often referred to as S-type bearings. See our overview of bearing inserts.

Technical information
Housings are made of gray cast iron according to EN-GIL-200/250 as standard. If higher strength properties are required, housings according to EN-GJS-400/450/500 are available.
Stainless steel housings are made of AISI304 or AISI316 and are therefore also highly resistant to salt water.
Plastic housing bearings are made of a technical polymer, which can also have anti-bacterial properties, depending on the requirements.
Housings made of steel sheet are supplied in a galvanized finish as standard. On request, we also offer them with a bright finish for customized coating/painting.
Please learn about the materials in the bearing inserts in the corresponding product group.
