RÖHM Slim live centre MK4 — Slim centre point with 60° tip for precise turning

RÖHM Slim live centre MK4 is a revolving centre designed for turning applications that require exact centring and a narrow tailstock footprint

• Slim live centre, MK4 taper
• 60° hardened tip for precise centring
• Max. runout 0.005 mm for high concentricity
• Suitable for rot. speeds up to 6,300 rpm

Consistent concentricity for reduced rework

The slim revolving centre delivers repeatable alignment thanks to its 0.005 mm runout specification and a 60° tip, which together ensure reliable contact and load distribution during turning. Runout (the deviation of the rotating tip from true centre) is a decisive factor for concentricity; a low value minimises vibration, tool wear and the scrap rate. For workshops handling large components, the rated support of 800 kg provides confidence when machining heavy shafts and flanges, contributing directly to higher first-pass yields.

Slim profile and MK4 taper for tight set-ups

A narrow housing and short projection allow closer tool approaches and improved access to component faces. The centre’s MK4 Morse taper guarantees a secure fit in compatible tailstocks, while the projection of 75.5 mm and compact housing diameter make it particularly suitable for cramped lathe configurations. The slim design reduces interference, enabling simpler fixture arrangements and fewer secondary operations, which helps streamline the production flow without compromising stability.

Smooth rotation and high-speed readiness

As a revolving centre, the unit rotates with the workpiece to reduce friction and heat buildup at the contact point; this improves surface finish and extends bearing and tip life. The centre is specified up to 6,300 rpm, making it appropriate for medium-to-high speed turning tasks. A tip length of 25 mm combines with the slim geometry to sustain reliable engagement while maintaining clearance for cutting tools. Overall, the design balances accessibility with load-bearing capability for demanding workshop use.

FAQ

What maximum rotational speed is supported? The RÖHM slim live centre MK4 (SKU 4000832077NW) is rated for up to 6,300 rpm, permitting use in many medium-to-high speed turning operations.

Which taper is required for mounting? This unit uses a MK4 Morse taper; the MK4 fitting secures the centre in compatible tailstocks and supports axial and radial loads during machining.

How precise is the centring performance? Centring precision is specified as a maximum runout of 0.005 mm, which supports high concentricity and reduced vibration during turning.

What workpiece weight can be supported? The centre is specified for workpieces up to 800 kg, making it suitable for stable support of heavy components in lathe operations.

Why choose the slim variant for tight set-ups? The slim profile and 75.5 mm projection reduce interference in confined tailstock areas, allowing closer tool approaches and simpler fixture layouts while maintaining reliable support with a 60° tip.
