Inca Selects Dugard Large-Capacity Lathe

Inca has purchased a Dugard Eagle 400 large-capacity lathe for the precision turning of components in aluminium, brass and perspex that can be up to 550mm in diameter. The lathe was required to exhibit rigidity, a good control-system interface and the ability to maintain a good surface finish on aluminium and plastics, as well as a range of steels.

The company also faces geometric demands for concentricity, flatness and parallelism. A pre-owned Quaser vertical machining centre with fourth-axis and Heidenhain control was installed for further general-machining tasks. Inca also took delivery of a large TOS W100A horizontal-boring machine with Heidenhain five-axis readout.

Schaeffler Catalog Details Large-Size Bearings

A 1,100-page technical compendium on large-size bearings is now available from Schaeffler (UK). Catalogue GL1 provides original equipment manufacturers, distributors and end users with an overview of the range of large-size bearings available from Schaeffler for heavy machinery and equipment.

The catalogue provides technical information on more than 10,000 bearings under the INA and FAG brands with outside diameters (ODs) of up to 2,800mm. It is designed to complement the company's existing HR1 rolling-bearings catalogue, which includes rolling bearings with ODs of up to 1,300mm. The new catalogue also contains bearing accessories, special rolling bearings, spherical plain bearings and bearing housings.

Schaeffler's INA- and FAG-branded large-size bearings are suitable for heavy industry applications, including steel, paper, mining and mineral processing, industrial power transmission, wind turbines, rail, production machinery and the energy sector. In most of these industries, large-size bearings are critical in ensuring the high reliability, energy efficiency and correct functioning of drive systems and other important machine components, according to the company.

Catalogue GL1 shows which products are suitable for specific bearing arrangements and which factors need to be considered during the design process, the tolerances required of the adjacent structures and how the bearing can be sealed effectively in light of the application conditions. The catalogue also provides detailed information on service life calculations, operating temperatures and loads, lubricant selection and suitability and how the products should be mounted, dismounted and maintained.

Revolvo Provides Flexible Large-Bearing Service

Revolvo is helping wind-turbine-maintenance companies to meet deadlines with its flexible service for large bearings. Flexible production allows the company to supply standard or bespoke solid and split bearings to order in sizes up to 1.5m outside diameter in a matter of weeks.

Revolvo also manufactures large, OE-standard solid bearings - cylindrical, taper-roller, thrust and deep-groove ball bearings - and can deliver them in a matter of weeks. This means that refurbishment projects can be delivered on-time and within budget by sourcing the bearings required for wind-turbine transmissions directly from Revolvo.

Revolvo manufactures solid bearings in sizes from 25mm bore to 1,500mm external diameter and SRB split roller bearings in sizes from 35mm bore to over 1,000mm internal diameter, plus imperial equivalents.

In addition, the company also manufactures inch, custom-designed and obsolete sizes of solid ball and roller bearings, which are used to keep older machinery in operation. All Revolvo bearings are produced to DIN PO/ABEC 1 standards, with up to P5 available on request.
