Stainless Steel Rod Bar

Details

This stainless steel bar complies with the welding joint symbols per MIL-STD-22. It features outstanding welding strength and reliability. Through precise processing, the accuracy and stability of each bar are ensured. Made of high-quality stainless steel, it possesses corrosion resistance, wear resistance and oxidation resistance, and is widely used in high-end machinery, aerospace, military and other industries.

Core Component Layout

Front - end Connection Module

Hexagonal Flange (HEX):It is used for precise connection with tools or equipment to ensure the stability of torque transmission.

Locating Pin Hole:It is used in combination with a locating pin, realizes dual - positioning in the transverse and longitudinal directions.

Intermediate Transition Section

Tapered Fitting Surface: The taper is 1:16 (standard Morse taper), with a surface finish of Ra≤0.8 μm, supporting gap - free fitting with the main spindle or fixture.

Seal Groove: Compatible with O - ring seals, achieving a protection level of IP54.

Rear - end Drive Shaft

Spline Section: The torque transfer range is 50 - 80 N·m.

End Chamfer: prevent assembly interference.

Key Dimensional Tolerances

Component	Technical Description

Materials and Surface Treatments

Base Material

Alloy Steel : Through quenching and tempering treatment (HRC38 - 42), with a tensile strength ≥1000 MPa.

Surface Hardened Layer: Nitriding treatment (0.1mm deep), with a surface hardness HV≥900.

Coating Options (Optional)

DLC Coating: Friction coefficient ≤0.15, and the wear life is increased by 3 times.

Nickel Plating:Excellent corrosion - resistance performance, suitable for humid environments.

Assembly and Debugging Recommendations

Installation Steps

Use a combination of locating pins and bolts for double - fixing, and tighten in stages.
The misalignment error between the spline shaft and the drive end should be controlled within 0.05 mm.
