The DLY WDCS25 25mm linear shaft is a solid precision shaft manufactured from GCr15 bearing steel. Its hardened, ground and hard chrome plated surface provides a smooth and wear-resistant running surface for LM25UU linear bearings and other linear bearing assemblies with a 25mm bore.
WDCS25 has a nominal diameter of 25 mm, a g6 shaft tolerance, HRC62±2 hardness and Ra0.4–0.8 μm surface roughness. DLY supplies standard lengths, cut-to-length shafts and drawing-based end machining for automation equipment, sliding tables, fixtures and replacement projects.
WDCS25 25mm Linear Shaft Features
- GCr15 bearing steel: provides a suitable base material for a hardened precision linear bearing shaft.
- Hard chrome plated surface: improves surface wear resistance and helps protect the shaft during normal storage and operation.
- g6 diameter tolerance: the WDCS25 diameter deviation is controlled from −0.007 to −0.020 mm.
- Ground and polished running surface: Ra0.4–0.8 μm roughness supports smooth movement with compatible linear bearings.
- Solid shaft construction: suitable for conventional unsupported shaft assemblies, fixtures and auxiliary guide mechanisms.
- Custom machining: cutting, tapped holes, external threads, radial holes, grooves, chamfers and stepped ends can be produced from drawings.

25mm Linear Shaft FAQ
Q: What bearing fits a 25mm linear shaft?
A: LM25UU is a common matching linear bearing. Other open, flanged or housed bearings may also use a 25mm bore, but the bearing structure and installation dimensions must be checked separately.
Q: What is the diameter tolerance of WDCS25?
A: The WDCS25 shaft uses a g6 tolerance. Its catalog upper deviation is −0.007 mm and its lower deviation is −0.020 mm.
Q: Is the 25mm linear shaft hard chrome plated?
A: Yes. WDCS25 is a hardened, ground and hard chrome plated GCr15 linear shaft. If a different material or surface condition is required, it should be stated separately in the inquiry.
Q: Can DLY cut a 25mm shaft to a custom length?
A: Yes. DLY can provide standard catalog lengths or cut the shaft to the required finished length. End machining can also be completed according to a drawing.
Q: Should I use a solid 25mm shaft or a supported round rail?
A: A solid WDCS25 shaft is suitable for conventional round-shaft assemblies. For a longer span or a structure that needs continuous bottom support, an SB25 or TB25 supported round rail may provide better resistance to deflection.
