Slim live centre MK4 with extended running point by RÖHM

Slim live centre MK4 with extended running point designed for accurate support of rotating workpieces in turning and heavy-duty lathe operations

• Max workpiece weight 700 kg
• Runout max 0.008 mm
• Max speed 6,300 rpm
• Morse taper MK4 mounting

High-precision support for demanding turning operations

The Slim live centre MK4 delivers high-precision bearing of rotating workpieces through an optimised bearing arrangement and a low runout specification. With a maximum permissible runout of 0.008 mm, the centre reduces vibration and improves surface finish on turned parts, which translates into fewer rework cycles and higher first-pass yields. The combination of a narrow profile and robust internal bearings means operators benefit from both accessibility and consistent precision across long production runs.

Slim profile and extended point for deeper support

A slim profile and an extended running point length of 37.5 mm provide secure support for workpieces that extend beyond standard centres, enabling deeper engagement without compromising stability. The reduced housing diameter of 42 mm allows closer approach to shoulders and tighter overhangs, while the 60° tip geometry ensures reliable centring. These attributes make the centre particularly suitable for shops handling long shafts or components requiring uninterrupted support along an extended length.

Robust capacity and drivetrain compatibility

Engineered to handle substantial loads, the centre is rated for a maximum workpiece weight of 700 kg and a top spindle speed of 6,300 rpm, offering a balance of strength and rotational performance. The mounting is a Morse taper MK4, with a shaft diameter of 31.267 mm, ensuring compatibility with common heavy-duty lathe spindles and straightforward integration into existing setups. The 60° tip angle aids concentric support and repeatability, helping to maintain tolerances during batch production.

Practical durability and workshop benefits

Constructed for industrial use, the rotating centre combines a compact external footprint with service-friendly assembly. The slim running point reduces interference when machining close to shoulders, while the robust internal mechanics support continuous operation under load. This results in improved process stability, reduced scrap rates and a more predictable machine lifecycle—outcomes that matter in production environments where uptime and repeatable quality are priorities.
