MOVE THE CURSOR — IT FOLLOWS
Since 2009
We keep your line
turning at tolerance.
A bearing is the cheapest part of the machine and the one that decides whether it runs. We build ours to the tolerance printed on the drawing, and we show the measurement that proves it.
HENERGY develops, manufactures and exports precision bearings. Our plant runs eight automated production lines and a metrology room with Marposs active gauging from Italy, plus FANUC and Mitsubishi control from Japan.
Dimensional and running accuracy corresponds to ISO class P5 and P4. On several series our parts drop in where imported equivalents were specified — same fits, same preload behaviour, at a lead time measured in weeks rather than quarters.

Capability
Measured in microns,
not in promises.
Every line is closed-loop. Marposs active gauging reads the workpiece during grinding, the control compensates, and the next part starts from a corrected datum — which is how a P4 class stays a P4 class at volume.
08AUTOMATED LINES
Grinding, superfinishing, assembly and inspection in one flow.
P5/P4ACCURACY CLASS
Dimensional and running accuracy to ISO classes, batch verified.
0.8µmRUNOUT HELD
On P4 spindle series, measured on the finished part — not on a sample of the run.

From enquiry to container
TYPICAL 4 – 8 WEEKS- 01
Technical review
Drawing, load case and fit checked by an engineer; equivalent or modified design proposed.
- 02
Quotation
Unit price, tooling, lead time and inspection plan issued in writing, usually within 48 hours.
- 03
Production & inspection
Run on the assigned line, sampled for noise, clearance and a dimensional report before packing.
- 04
Export & dispatch
Neutral or branded packing, documents to your broker's format, shipment tracked to door.
Real parts
From the line,
not from a catalogue.
An enquiry can be answered with photographs of the batch it will come from — cage type, surface finish, marking and packing, shot on the bench before dispatch.
Every batch leaves with its own measurement file: bore, OD, width, runout and clearance, taken on the finished part. Ask for the report of the batch you are being quoted and we will send it with the price.

A drawing, a competitor reference or a photo of the failed part is enough to start. Technical questions go straight to an engineer, not a mailbox.
