BALL GUIDE BUSH

BALL GUIDE BUSH

BOLEXP ball guidance bushes are made up of an outer casing of steel for rolling, hardened and ground, which holds fixed inside a high-resistance bronze cage for guiding the balls running along the cage.The translation system consists of several rows of precision balls circulating endlessly. The great novelty of BOLEXP ball guidance bushes is that balls do not run aligned, with the translation motion, but at a slight angle, thus enlarging the contact area with the shaft and enabling greater load capacity. This patented system represents an utter innovation in the linear guidance market. An all-metal structure makes bushes extremely resistant to high temperatures. BOLEXP bushes are supplied in a variety of three outer forms, all of them equipped with the same inside structure.

MOULD CENTERERS

MOULD CENTERERS

All our range of centerers that we present in this catalogue edition include graphite insertions in order to self-lubricate its working in one of the pieces, the other one being coated with a TiN treatment at 2300 Hv for reducing seizing. Side centerers make it possible to 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 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 BRONZE

SELF-LUBRICATED BRONZE

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.

Implementing these systems results in a significant reduction in seizing problems and maintenance costs, as well as in gas emission caused by oil heating. This permits to operate at high temperatures that in some cases can reach 400º C (752º F).

The presence of aluminium in bronze reduces the attack of atmospheric agents and warm gases, whilst at the same time exhibiting great stability against distilled water, saline water, seawater or acid well water. Bleaches, except for ammonia, are harmless to it. Moreover, a protection layer produced by the material itself acts very favourably against the corrosive effect of sulphur and oxydizing gases.

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.

he graphite used is a material with an extremely low chemical-inertia level, not interacting with most elements in nature under normal conditions. This ensures regular behaviour through the piece lifetime without unexpected contingency.

BOLEXP item construction exhibits a graphite distribution over the guide surface of about 25%-35% of the total, thus guaranteeing proper lubrication of the tool to construct. In addition, 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.

Company details

BOLEXP NORMALIZADOS, S.L.U.

Bolexp Normalizados,S.L.U. was born to respond to the growing demand for offering a product able to meet the needs of a market increasingly specialized and innovative, and as a way to provide a quick and effective service to the customer.

With an exceptional location just 15 kilometers away from Barcelona, linked by the highway A-7 and next to the largest logistics center of Vallés, our company can provide a quick material delivery service both nationally and internationally.

Over the last few years, our Bolexp guidance systems have undergone a constant process of evolution and improvement in order to respond to the continuous progression of the market and keep pace with the requirements of our customers. Our policy of comprehensive control of each and every manufacturing process, since the reception of raw material until the final product comes to our warehouses, allows us to ensure all the time that our current articles, as well as those that could be added in the future, come from our premises, responding therefore as manufacturers of their quality and traceability. This constant effort to improve has led us to expand our technical equipment and installations in order to offer a wider range of products focusing on research and development.
