Product category: Standard parts for moulds

freeLub Ball Bush

The new self-lubricated ball bush has been developed to work with little maintenance and is able to operate in dust conditions.

The patented system with ball guidance and graphite insertions in the bronze cage allows for the usual Bolexp-bush fluid working, without requiring a continuous maintenance.

Furthermore, the new channel grouping, with double contact lines, allows a bigger load capacity, up to +25%. And the steel used for the outer cage has high resistance to wear.

Also, the grease retainers in the ends of the bronze cage ensure the retention of graphite particles and prevent dirt from getting inside.

Mould Centerer

ur range of centerers include graphite insertions in order to self-lubricate its operation in male pieces, the female one being coated with a TiN treatment at 2300 Hv for seizing reduction.

Side centerers guarantee the appropriate alignment for the main plates in the mould. The fact of making the allocations in the mould bearer axis allows us to ensure the zero point of the whole structure.

The flat centerer keeps the axis invariable where it is located as well as absorves the +B27 longitudinal dilatations of that axis.

The system of fixing to plate of our centerers allows to make all the mechanization of plates, figure allocations and centering system in a single operation, which guarantees a greater precision of execution.

Self-lubricated Guidance

The development of self-lubricated guidance systems arises from the need to solve the existing problems involved in lubrication. These are due either to the difficulty of access or to the convenience of continuous and permanent lubrication, which oils fail to ensure.

Graphite insertions, acting as a solid lubricant, allow to keep an excellent level of lubrication for plates or bushes through all their lifetime, ready for use at any time.

Through use, the bronze structure wear causes graphite insertions wear. The graphite dust resulting from this slight wear will be the responsible for lubricating the whole of the contact area.

The graphite insertions used are relatively small, in comparison with other manufacturers, in order to minimize the impact on bronze bush consistency and maximize the dispersal of solid lubricant.
