Who uses the Apollo 1250 x 5000 and for what
The Bernardo Apollo 1250 x 5000 is one of the compact heavy-duty parallel lathes in the Apollo range, featuring 5,000 mm between centers with a 1,250 mm diameter: suitable for machining long shafts and medium profiles. The reinforced bed with a width of 755 mm and the ISO A2-15 spindle nose define its operating range: machining shafts, profiles, and cylindrical parts typical of medium-large industrial mechanical workshops. The included 3-axis digital readout ES-12 V, the power transmission via cardan shaft with hydraulic clutch, and the 36 speeds from 3.15 to 400 rpm with gear change cover any material and geometry. The soft start of the spindle with mechanical coupling reduces stress on components when starting heavy workpieces. In Krollit's customers' workshops, the Apollo 1250 x 5000 is chosen by industrial mechanical workshops, shipyards for repair and reconstruction of axles and shafts, manufacturers of turbine and generator components, and workshops specializing in precision turning of heavy workpieces.
Its place in the Bernardo range
The Bernardo Apollo family is the line of heavy-duty parallel lathes for industrial applications. It consists of 12 models organized by turning diameter over the bed (1000, 1250, 1600, 2000 mm) and distance between centers (1,500, 2,000, 3,000, 5,000, 8,000 mm). Family 1000-1250 (this model): ISO A2-15 spindle nose, 22 kW motor, 36 speeds from 3.15 to 400 rpm, 755 mm bed. Suitable for precision machining of medium-large workpieces. Above it: 1600 family with ISO A2-15 (970 mm bed) for more voluminous workpieces while maintaining a compatible structure; 1600 family with MT 7 (1,100 mm bed) for heavy industrial applications; 2000 family (top, MT 7, 22-30 kW motor, 2,300 mm gap) for heavy industrial production. Alongside the 1250 x 5000 in the same family: Apollo 1000 x 8000, Apollo 1250 x 1500, Apollo 1250 x 3000, Apollo 1250 x 8000. The choice between models in the family depends on the length of the workpieces: for long shafts, 8,000 mm distance between centers, for standard shafts 3,000 mm, for compact short workpieces 1,500 mm.

Frequently asked questions
What are the typical application sectors for the Apollo 1250 x 5000?
Naval (marine shafts, propellers, gearboxes), energy (turbine shafts, generators), heavy mechanical (cylinders, pulleys, gears). The 5000 mm distance between centers and 1250 mm turning diameter define its operating range.
Examples of typical workpieces: long transmission shafts (components for marine engines), large cylindrical profiles (components for industrial machinery), industrial pipe flanges. For specific workpieces, check the maximum diameter, length, and weight of the workpiece in relation to the machine's capabilities in advance.
What operating space does it require in the workshop?
Machine dimensions 8.1 × 1.88 × 1.92 m. For operational use (loading/unloading workpieces, handling, maintenance access), a total area of at least 1.5x the machine dimensions is required, with adequate ceiling height.
Installation requires industrial flooring or a reinforced concrete foundation sized for the weight of the machine plus typical workpieces. For initial installation, it is recommended to consult a qualified installer for structural and conformity assessment of the site.
Is the ES-12 V 3-axis digital readout really necessary?
Yes, for precision production. The DRO displays the exact axis position in real time to the hundredth of a millimeter, eliminating reading errors from graduated handwheels. On a heavy-duty lathe of this size, positioning accuracy is crucial for machining quality.
Without a DRO, positioning accuracy depends on visual reading of the handwheels and compensation for screw backlash: errors of 0.1-0.2 mm are typical. With a DRO, positioning accuracy easily reaches 0.01 mm. On the Apollo, it is included as standard, unlike many entry-level industrial lathes from other brands where the DRO is an expensive optional accessory.
Is it better to get an Apollo 1250 or upgrade to the 1600 diameter?
It depends on the maximum diameter of typical workpieces. Up to Ø 1000 mm on the bed, the Apollo 1250 is correctly sized. For workpieces regularly over Ø 1062 mm, the 1600 family is mandatory.
The 1600 family has a reinforced bed of 970 mm (vs 755 mm), extended X-travel of 820 mm (vs 630 mm), and higher weight. The cost is higher. For growing workshops or those with variable needs, it is strategically preferable to size correctly in advance. For established workshops with standardized production at the current maximum diameter, the additional investment is not justified.
What is the expected lifespan of an Apollo lathe?
For standard industrial use, the Apollo range is designed for an operational life of over 25-30 years with regular maintenance. Wear parts (bearings, guides, lubrication system, clutches) can be replaced with original Bernardo spare parts.
The stabilized, hardened, and ground cast iron structure (a characteristic of Apollo lathes) does not wear significantly: the bed and headstock maintain precision for decades with correct maintenance. Mechanical contact components are designed for continuous industrial use and are replaced periodically. Original Bernardo spare parts are available from stock with 3-5 business day shipping. For intensive use, a semi-annual preventive maintenance plan is recommended.
