How much does the Hartford HSA-528EA cost?
Price estimate
We do not have a price for the Hartford HSA-528EA that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Hartford HSA-528EA carries 20,000 kg (44,092 lb) on a 5,000 x 2,500 mm (196.9 x 98.4 in) table. X travel is 5,000 mm (196.9 in) and Y travel 2,800 mm (110.2 in), which makes it the entry point of the heavier five-metre models in the five-face HSA line.
Two neighbours frame it. The HSA-523EA is the lighter five-metre machine, 2,200 mm wide and rated at 15,000 kg (33,069 lb). The HSA-532EA has the same table and the same 20,000 kg as this model but 3,200 mm (126.0 in) of Y. Choosing between the 528EA and the 532EA is therefore a question about side faces, not about part size: both hold the same workpiece, and the 532EA lets an angular head travel further past the table edge.
For a part that only needs its top and its two ends worked, the 528EA's Y travel is enough. The ends are reached along X, where the five-metre travel equals the table length.
The table lists the 10,000 rpm spindle as a hybrid built-in type and the gear head at 6,000 rpm with 8,000 rpm optional, all in #50 with BT-50 shanks. Z travel is 1,000 mm or 1,200 mm. Hartford names the x28 EAY, x32 EAY and x36 models as having Y-axis ballscrew support as standard, which leaves it open for this one.

Strengths & Limitations
Strengths
- 20,000 kg (44,092 lb) table load
- 5,000 x 2,500 mm (196.9 x 98.4 in) table with 5,000 mm of X travel
- Hybrid built-in spindle at 10,000 rpm or gear head at 6,000 rpm
- Slant beam design and Z axis on four linear guideways
Limitations
- Y travel of 2,800 mm (110.2 in) is the shortest among the 2,500 mm wide five-metre models
- Y-axis ballscrew support is not stated as standard for the x28 EA
- The 8,000 rpm gear head is an option, not the base spindle

Frequently Asked Questions
01
The table is rated for 20,000 kg (44,092 lb). It measures 5,000 x 2,500 mm (196.9 x 98.4 in) and has nineteen T-slots. Hartford's table gives no machine weight for this model.
02
Both have a 5,000 x 2,500 mm table rated at 20,000 kg. The HSA-532EA has 3,200 mm (126.0 in) of Y travel and the HSA-528EA 2,800 mm (110.2 in). Pick the wider travel if angular heads must work along the sides of full-width parts.
03
5,000 mm (196.9 in) in X, 2,800 mm (110.2 in) in Y and 1,000 mm in Z, with 1,200 mm of Z available as an option. The spindle taper is #50.
04
Hartford describes a complete angular head design package for the model, shows an automatic universal head, and provides an automatic angular head switching compartment so that heads are exchanged without the operator.
