MOVE THE CURSOR — IT FOLLOWS

Find a bearing Designation, series or bore — answered by an engineer, not a filter.

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.

Product range

Eleven families.
One tolerance standard.

Roller and ball bearings for radial, axial and combined loads — plus a workshop that builds to drawing when the catalogue stops.

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.

We will send the answer.

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.
