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.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eLogistics and Krollit support\u003c\/h3\u003e\n\u003cp\u003eBernardo shipping in 5-9 working days (7 days to the South).

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.\u003c\/p\u003e\n\u003cp\u003eThe 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 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.
