The hubs we manufacture are used in disk harrows which are sold both at domestic and foreign markets. There are two versions available: a regular and maintenance-free hub. The latter one is used increasingly often as it allows for reducing the costs of overall maintenance. The dimensions of the regular hub are as follows: Ø 152 mm, height: 88 mm, six openings, maintenance-free hub dimensions: Ø 152 mm, height: 69 mm, six openings.
