DNM Tulejka 6 x 5 mm SDNM0025 — bush/sleeve 6×5 mm

DNM Tulejka SDNM0025 is a precision metal sleeve with nominal dimensions of 6 × 5 mm designed to guide, space or protect shafts, cables and fasteners in mechanical assemblies. Supplied as a single-component bush, this compact sleeve provides a consistent inner bore for alignment and a controlled outer diameter for press-fit or clearance mounting. It is intended for use in repair, maintenance and equipment assembly where reliable positioning and wear protection are required.

Advantages

The DNM 6×5 mm sleeve offers accurate inner and outer dimensions that aid repeatable alignment of rotating or fixed components. Its single-piece construction reduces the risk of misalignment compared with improvised solutions and provides a simple wearing surface that can be replaced if necessary. The small axial length and compact profile make it suitable for confined spaces while still delivering mechanical protection for shafts, cables and fastening elements.

Suitable for

• Guiding small-diameter shafts or pins
• Insulating and protecting cables where they pass through panels
• Providing spacing and alignment between mating parts
• Acting as a replaceable wear sleeve in light-duty mechanisms

Key specifications

• Outer diameter: 6 mm
• Inner diameter: 5 mm
• Component type: single-piece sleeve / bush
• Typical applications: guidance, spacing, insulation, wear protection

How to use

Select a sleeve orientation that aligns the inner bore with the shaft, cable or fastener axis. For press-fit installation, ensure the receiving hole matches the sleeve outer diameter and apply steady, centered force until the sleeve seats flush with the mating surface. For clearance fits, confirm adequate concentricity to prevent wobble. Where necessary, trim or deburr panel edges before inserting the sleeve to avoid damage to the inner bore and to ensure smooth passage of the guided element.

Usage recommendations

Choose this sleeve when precise inner bore control and a small overall profile are required. Verify material compatibility with the guided element and operating environment; in corrosive or high-load conditions, consider alternative materials or additional lubrication. Inspect the sleeve periodically for wear and replace if inner bore or outer surface shows deformation that may affect alignment.
