Who uses the DP2 and for what
The Bernardo DP2 is the intermediate manual rack and pinion press in the DP family, a typical choice for general workshops seeking a compromise between capacity and footprint. With a useful workpiece height of 190 mm and an effective force of 1,285 kg, it covers the vast majority of mechanical workshop operations: inserting/extracting standard bearings, mounting bushings, straightening small shafts, bending wire, and light broaching. Its 30 kg weight provides adequate stability while remaining transportable by one person. The effective force of 1,285 kg is the highest in the DP range at a weight lower than the D5 (160 kg): an optimized force-to-weight ratio for everyday artisanal use. In Krollit customers' laboratories, it is the most frequent choice among manual rack and pinion presses for general workshops, maintenance departments, and artisanal laboratories working with standard-sized parts.
Its place in the Bernardo range
The DP2 is the most balanced model in the DP family. Below it is the DP1 (force 1,140 kg, height 135 mm, weight 11 kg) for small applications; above it is the DP3 (force 1,181 kg, height 300 mm, weight 40 kg) for taller workpieces; and the D5 (force 1,560 kg, height 445 mm, weight 160 kg cast iron) for heavy-duty applications. The DP2 has the highest effective force in the range under 50 kg in weight: the DP3 trades off workpiece height (300 mm) for lower force (1,181 kg), the lever-rack ratio is balanced differently. For the vast majority of general workshops, the DP2 is the correctly sized choice: 190 mm workpiece height covers standard bearings, bushings, and small shafts, 1,285 kg force handles most standard operations, 30 kg weight allows occasional repositioning.
Logistics and Krollit support
Bernardo shipping in 5-9 working days (7 days to the South). At 30 kg, it is shipped in protective packaging and can be handled by one person. It must be fixed to a sturdy workbench using the mounting holes. Original Bernardo spare parts available from stock with 3-5 working days shipping. Customer support in Italian available.
Who the DP2 is for
| Profile |
Compatibility |
Reason |
| Passionate hobbyist |
Recommended |
Balance of capacity-footprint suitable for advanced hobby use on standard-sized mechanical components. Durable tool for years of intermittent use. |
| General mechanical workshop |
Recommended |
Most frequent choice for everyday artisanal use. 1,285 kg force and 190 mm height cover the vast majority of standard mechanical workshop operations. |
| Maintenance department / artisanal workshop |
Recommended |
Optimal compromise between capacity and portability. For workpieces exceeding 190 mm in height, consider DP3 or D5. |
Not suitable for: working on pieces over 190 mm high (consider DP3 or D5); applications requiring forces over 1.3 tons (D5); high-volume series production (the press is manual); on-site use without a stable support bench.

Frequently Asked Questions
Is the DP2 or DP3 better?
It depends on the typical height of the workpieces. The DP2 has a workpiece height of 190 mm and a force of 1,285 kg; the DP3 has a height of 300 mm but a lower force (1,181 kg). For small workpieces requiring high force, the DP2 is preferable; for tall workpieces, the DP3.
The key difference is not just dimensional but a trade-off: the DP3 sacrifices force for workpiece height, the DP2 sacrifices height for force. For use primarily with standard bearings and bushings, the DP2 is correctly sized. For tall workpieces (shafts, posts, profiles), the DP3 is necessary. The price difference is small.
Can I press bearings onto medium shafts?
Yes, up to 190 mm workpiece height. For bearings on taller shafts, consider DP3 (300 mm) or D5 (445 mm).
Most bearings on workshop shafts fall within the 190 mm useful height. For specific applications (industrial motor shafts, long spindles), a press with greater useful height may be necessary. Check the total height of the assembled component (bearing + shaft overhang) before choosing.
Does it need to be fixed to the bench or is it stable on its own?
It must be fixed to the bench using the mounting holes. The 30 kg weight is not sufficient to counteract the pressing reaction: without fixing, the machine will lift during operation.
Standard bench bolts are sufficient. The bench must be sturdy and sized to withstand lateral forces during pressing. For workshops without an adequate bench, an optional heavy base is available as an accessory. For temporary or portable use, consider smaller models (DP1).
How fast is it at inserting standard bearings?
For standard bearings, the complete cycle (positioning, pressing, removal) takes 30-60 seconds. Speed is limited by workpiece positioning, not by the rack and pinion.
The DP2's rack and pinion has adequate travel for most pressing operations in a single pass. For deep insertions, it may be necessary to pump the lever multiple times: each lever stroke advances the ram by a few millimeters. For high-volume series production, consider hydraulic presses.
How long do the rack and gears last?
In intermittent artisanal use, the DP2 is designed for decades of life with minimal maintenance (periodic lubrication). Mechanical components are sized for regular use without significant wear.
The sign that intervention is needed is excessive play in the rack or difficulty of movement. Routine maintenance: grease the rack every 6-12 months depending on use. Original Bernardo spare parts available from stock with 3-5 working days shipping.
