WABO DEC S - Spherical bearings
WABO DEC S bearings consist of a backing plate with a convex spherical surface (rotational element) and a backing plate with concave spherical surface between which a PTFE sheet and the mating material form a curved sliding surface. They are also used in combination with flat sliding elements and guide to form free and guided bearings. WABO DEC S combined with a flat sliding element can be used together with a restraning ring to form fixed bearings.
WABO DEC S bearings are capable of transferring applied vertical and horizontal loads between the superstructure and substructure. They permit rotational movement about all axes and, where appropriate, a flat sliding element allows movments with a minimum of friction.
DESIGN AND MANUFACTURE
WABO DEC S bearings can be designed and manufactured in accordance with the requirements of any national or international applicable standard.
Types : WABO DEC S bearings are supplied in four types:
- Fixed spherical bearings which resists horizontal forces preventing movements in any direction
- Guided sliding spherical bearing which allows sliding movements along the longitudinal axes of the bridge and resists the horizontal forces in the perpendicular one.
- Guided sliding spherical bearing which allows sliding movements along the transverse axes of the bridge and resists the horizontal forces in the perpendicular one.
- Multi-direction sliding spherical bearing which
allows sliding movements in all horizontal
