Röhm H Pro live centres in standard design are precision components designed for counter-clamping and axial support of the workpiece during turning and grinding operations. They are suitable for standard clamping situations where the workpiece must remain stable, centred and correctly supported during rotation. Their function is to reduce vibration, deflection, instability and geometric variations that may affect surface quality, concentricity and dimensional repeatability.

The H Pro series is an all-round live centre suitable for most industrial applications on conventional lathes, CNC lathes, automatic lathes and grinding machines. The hardened and ground body ensures wear resistance, mounting stability and accurate fitting with the machine. Hardening improves service life even under continuous working conditions, while grinding contributes to the geometric quality of the live centre and to regular support of the workpiece.

The 60° tip angle allows use on many mechanical parts, such as shafts, pins, bushes, cylindrical components, turned parts and precision workpieces. This geometry is a widely used standard solution in turning and grinding processes because it provides effective support in the workpiece centre and helps maintain alignment with the machine axis.

An important technical feature of the H Pro series is the proven three-bearing system, designed to withstand high axial and radial loads. This configuration allows the live centre to operate with good stability even under combined loads, maintaining smooth and regular rotation. Lifetime lubrication reduces the need for periodic maintenance and makes the product suitable for production departments with repetitive cycles, frequent use and the need for continuous operation.

The maximum concentricity deviation is 0.005 mm for the H Pro version and 0.003 mm for the HP Pro version, intended for applications requiring even higher precision. This parameter is essential when the workpiece must meet tight dimensional tolerances, high surface quality and accurate geometric control. A live centre with low concentricity deviation helps reduce runout errors, ovality, form defects and machining instability.

These live centres are suitable for machining steels, alloy steels, light alloys, non-ferrous materials and industrial components used in automotive, precision engineering, machine building, aerospace and turned-part production. In turning, they help stabilise long or deflection-sensitive workpieces; in grinding, they help maintain smooth and controlled rotation during finishing operations.

For technicians, maintenance operators and workshop specialists, the correct choice of live centre must consider machine size, expected load, rotational speed, material being machined, required precision level and application type. Correct selection improves process stability, reduces rejects, preserves the accuracy of the machine-fixture-workpiece system and increases machining reliability.

Tadaah offers Röhm H Pro standard live centres as a technical solution for professionals requiring a universal, robust and precise live centre for turning and grinding. The combination of hardened and ground body, 60° tip angle, three-bearing system, lifetime lubrication and high concentricity makes this series suitable for industrial machining where stability, service life and support quality are essential requirements.
