Carbon Steel Shaft Collars

Carbon Steel Shaft Collars

Product Description

Our high-strength, single-split clamping shaft collars are engineered for heavy-duty industrial assemblies. Machined from robust S45C carbon steel with a protective black oxide finish, this one-piece collar provides exceptional axial holding power. It compresses uniformly across the shaft's circumference, minimizing slippage under heavy loads while protecting precision-ground surfaces from damage. Adjustments can be made efficiently utilizing a single alloy steel cap screw.

Bore Sizes (Metric): 6 mm to 60 mm
Bore Sizes (Imperial): 3/13" to 2-4/11" (approx. 0.24" to 2.36")
Material: Medium Carbon Steel (45 #)
Surface Finish: Black Oxide Treatment (Anti-corrosion)
Clamping Hardware: High-Tensile Alloy Steel Socket Head Cap Screws

Primary Advantages of the Single-Split Carbon Steel Design
1.High Axial Holding Power: For applications subjected to heavy shock loads, rapid reversing cycles, or intense vibration, carbon steel is a highly robust material choice. It resists stretching or distorting under high clamping torques, helping to ensure the collar remains firmly anchored to the shaft.

2.Non-Marring Shaft Protection: Standard set-screw collars can dig deep craters into steel shafts, making future adjustments difficult and risking damage to linear bearing seals. Because the single-split collar clamps using uniform surface friction rather than a penetrating screw, it leaves the shaft unmarked, allowing you to reposition components and perform maintenance without compromising precision g6 tolerances.

3.Efficient Single-Fastener Adjustment: Unlike two-piece (double-split) collars, which require balancing the torque of opposing fasteners, the one-piece collar utilizes a single screw. Repositioning simply requires loosening the single screw, sliding the collar along the shaft, and re-torqueing the fastener.

4.Corrosion-Resistant Black Oxide Finish: The steel is treated with a chemical black oxide finish. This treatment provides a layer of mild corrosion resistance to help prevent rust from humidity, while adding a professional, matte black aesthetic to the assembly.
