Zentrierkegel MK4 A.-L.100mm — Centre cone, MK4 Morse taper, 60° point angle (RÖHM)

The Zentrierkegel MK4 A.-L.100mm is a Morse-taper centre cone designed for precise support and rotation of medium to heavy workpieces in turning and inspection applications

• Morse taper MK4 shank
• 60° precision point angle
• 100 mm projection for deep centres
• Supports up to 800 kg workpieces

Stable support for heavier turning operations

A centre cone with a Morse taper MK4 shank provides a secure seating in the spindle or tailstock, reducing axial play and improving concentricity during turning. The 100 mm projection permits access to recessed centres while the 64 mm housing diameter increases the bearing surface, resulting in more consistent rotation under load. With a specified 800 kg maximum workpiece rating, this component is suitable where robust, repeatable centring is essential; the clear numeric limits simplify risk assessment and setup planning for production and workshop tasks.

Precision geometry that improves concentricity and inspection

The 60° point angle is a standard geometry for centring cones, offering a well-defined contact zone that balances penetration and support. A sharper or flatter angle would change seating behaviour; the 60° form concentrates load at a predictable apex, which helps to reduce runout and improves repeatability in measurement and machining processes. For operations requiring close tolerance alignment, the precise apex profile and slim pointed form contribute to stable datum formation and easier subsequent machining or metrology tasks.

Workshop-ready design for reliable daily use

Constructed for mechanical compatibility and straightforward mounting, the taper shank format ensures rapid fitting and removal without special adapters. The combination of a standard Morse taper and a compact housing results in a component that works with common centres and tailstocks while offering the mechanical strength to handle heavier assemblies. Regular inspection of the contact surfaces and correct seating are sufficient to maintain service life; the uncomplicated design keeps maintenance minimal while delivering dependable centring under continuous workshop conditions.
