Erdvark Offset Disc Bearings – DB

Erdvark Engineering are on the forefront of Disc Bearing development. Erdvark developed each component and manufacture the component our self to the highest specifications. We use a taper roller bearing and Duo-Cone seals. The bearing is developed that no dust or dirt will enter the sealed unit under normal working conditions. The bearing need no lubrication or daily service. The Bearing units are assembled in our factory with a special high quality lubricant and the correct volume of lubricant to prevent over lubrication and cause leaking. The Bearings are assembled with special tools and pressed together.

a) Erdvark is the leading manufacturer of disc implements and each bearing used on a specific disc implement is manufactured to the implement specification.
b) There are 8 different Bearing configurations in the Erdvark range to fit our wide range of disc implements.
c) All the disc bearings are fitted with Duo-Cone seals keeps dust and dirt out of the bearing housing and that will ensure years of trouble free operation.
d) None of the Bearings are bolted on to the frame of the disc implement. It is lying into a cradle that also serve as a wear plate to prevent the bearing to get damaged from soil and other materials.
e) This configuration allow the high tensile axles and Duo-Cone seals to flex and do not get abnormal wear on the Bearing systems.

Erdvark has different maintenance free Bearing Configurations for all Erdvark Disc Implements.
