Spindle shaft DNM Trzpień 210 mm — DNM model SDNM0018, 210 mm length

DNM Trzpień 210 mm is a 210 mm spindle shaft designed for use in compatible machinery and assemblies. The component provides a defined cylindrical length and seating surface intended for mounting, rotation or coupling tasks where a precise 210 mm spindle is required. It is supplied as a single shaft element suitable for repair, replacement and routine equipment maintenance in workshops and production environments that accept DNM-compatible parts.

Advantages

The spindle shaft offers a fixed 210 mm length that simplifies alignment and installation in systems designed for this dimension. Machined for concentricity and consistent diameter, the part enables predictable fit with bearings, couplings or tooling fixtures. Its straightforward geometry and single-piece construction reduce the number of mating parts and potential play, supporting stable rotation and repeatable positioning.

Suitable for

• Replacement of worn or damaged spindles in compatible machinery
• Workshop repairs and equipment refurbishment
• Jig, fixture or tooling setups requiring a 210 mm spindle element
• Prototyping and small-scale production where standard shaft lengths are used

Key specifications

• Overall length: 210 mm
• Type: spindle shaft (single-piece)
• Typical applications: rotational mounting, coupling, tooling support
• Material and surface finish: machined metal suitable for bearing and coupling interfaces

How to use

Measure mating component dimensions and bearing bores to confirm compatibility with the 210 mm spindle shaft before installation. Install the shaft into the appropriate housing or fixture, ensuring proper seating and alignment. Use recommended fastening methods for the machinery in question, such as set screws, retaining rings or threaded collars, and verify concentricity with measuring tools. After installation, perform a run-in check at low speed and inspect for excessive play or vibration before returning the equipment to normal operation.

Usage recommendations

For reliable operation, clean contact surfaces prior to assembly, apply appropriate lubrication to bearings and interfaces, and follow the equipment manufacturer's tolerances for shaft fits and fastening torque. Regular inspection for wear or corrosion will extend service life and maintain performance.
