Bushings, Sleeves & Spacers — CNC Turned
Plain bushings, threaded bushings, spacer sleeves and clamping sleeves on the NLX 2000. Fits from H7, threads to M30 — from 1 piece in 5–8 working days.
Bushings & Sleeves from the Turning Specialist
Bushings and sleeves are the most common rotationally symmetric components in mechanical engineering. Whether as plain bearings, thread inserts, spacers or clamping devices — the requirements for fit and concentricity are high.
On our DMG Mori NLX 2000 we manufacture bushings and sleeves with internal and external threads, fits from H7 and complete machining in one setup. This ensures highest concentricity between inner and outer diameter.
Types & Variants
From simple spacer sleeves to complex threaded bushings — all types from one source.
Plain Bushings
Cylindrical bushings with tight bore fit (H7). As plain bearings, guide bushings or bearing bushings. From bronze, brass or steel.
Threaded Bushings
Bushings with internal thread (M3–M30) and/or external thread. As thread inserts, reducers or adapters.
Spacer Sleeves
Spacers with defined length tolerance. For bolted connections, shaft assembly and sub-assemblies.
Clamping Sleeves
Slotted sleeves with tapered bore for friction-lock connection on shafts. DIN 1481 / ISO 8752.
Adapter Bushings
Transition bushings with two different diameters or fits. For connecting different shaft sizes.
Flanged Bushings
Bushings with shoulder flange for axial positioning. As bearing bushing with integrated axial stop.
Benefits of Our Bushing Manufacturing

Questions about Bushings & Sleeves
Q1What bushing types do you manufacture?
Plain bushings, threaded bushings, spacer sleeves, clamping sleeves, adapter bushings and flanged bushings. Special shapes from drawings.
Q2What fits can you produce?
All common ISO fits: clearance fits (H7/f7, H7/e8), transition fits (H7/k6, H7/m6) and interference fits (H7/p6, H7/r6).
Q3From which materials do you manufacture bushings?
Aluminium, stainless steel, free-cutting steel, quenched & tempered steel, brass, bronze, copper and plastics (POM, PEEK, PA, PTFE).
Q4How do you ensure concentricity?
By manufacturing inner and outer diameter in one setup on the NLX 2000. Concentricity ≤ 0.01 mm is standard.
Q5Can bushings also be manufactured with cross-holes and threads?
Yes — the NLX 2000 has live tooling and C-axis. Cross-holes, threads and flats are manufactured in the same setup.
Q6What is your minimum order quantity?
From 1 piece. For series demand from approx. 50 pieces we use the bar feeder for economical production.
Q7How long does delivery take?
Standard delivery 5–8 working days. Express from 3 working days available. Individual scheduling for series call-offs.
Q8Can you reproduce bushings from a sample?
Yes — send us a sample bushing, we measure it and manufacture your bushing accordingly. Even without existing drawings.
