Plain Cylindrical Bushing Custom Steel Hollow Spacer Sleeve with One-End Chamfer for Shaft Support

Product Content:

From Qimao Metal Manufacturer the Plain Cylindrical Bushing Custom Steel Hollow Spacer Sleeve with One-End Chamfer for Shaft Support material is typically plain carbon steel – A36, 1045, or Q235B depending on the customer’s strength requirement. For corrosion resistance we can hot-dip galvanize, electroplate zinc, or leave it bare with a light oil coat for rust prevention during shipping. The chamfer we do on one end is standard – about 1mm to 2mm wide at roughly 45 degrees, but we can adjust angle or width if your assembly requires a longer lead-in. The hollow center is bored, not drilled, so the inside surface comes out smoother and more concentric than a drilled hole. We hold ID tolerance around plus/minus 0.05mm, OD plus/minus 0.05mm to 0.1mm depending on diameter, and length within plus/minus 0.5mm. We can go tighter but we’ll talk to you first about whether you actually need it.

Product Details:

Plain Cylindrical Bushing Custom Steel Hollow Spacer Sleeve with One-End Chamfer for Shaft Support– basically a straight steel tube with clean cut faces. One end gets a slight chamfer, maybe 1×45 degrees, just enough to guide it into the housing bore without shaving metal on insertion. The other end stays square. No rolling elements, no lubricant grooves, no seals – it’s a simple spacer and locating sleeve. You slide it over a shaft or press it into a bore to take up radial clearance, control axial position, or protect the housing from wear. We make these on CNC lathes from solid bar, bore out the center, turn the OD, part off to length, deburr, and chamfer. Surface finish held around 3.2Ra. Straightness and concentricity are controlled within normal machining limits.

Core Feature:

• Plain Cylindrical Bushing Custom Steel Hollow Spacer Sleeve with One-End Chamfer for Shaft Support , eases insertion into tight bores – saves time during press-fit assembly and prevents scoring of mating surfaces.

• Bored ID gives cleaner surface finish than drilled holes – less friction against the shaft and better concentricity.

• Straight, square-cut ends – the bushing stands square against shoulders and locating faces, no rocking or misalignment.

• No sharp edges inside or out – our deburring step means you don’t cut your hands during handling or installation.

• Simple geometry, straightforward machining – this keeps cost down and delivery short. We can turn around small batches in days.

• We can harden the material if required for high-wear applications, but we always confirm intended use before suggesting heat treatment.

Wide Usage:

• Plain Cylindrical Bushing Custom Steel Hollow Spacer Sleeve with One-End Chamfer for Shaft Support for motor shaft spacers – setting correct axial position between bearing and housing shoulder.

• Gearbox assemblies – aligning a gear on a shaft while providing a wear surface at the interface.

• Bearing support sleeves – temporary or permanent alignment in pillow block and flange bearing installations.

• Conveyor rollers – spacer and locating sleeve between roller ends and frame mounts.

• Die set guide pins – a simple hardened sleeve inside the guide post housing for wear resistance.

• Automated equipment – any shaft pass-through where you need a replaceable wear liner without replacing the whole housing.

Installation & Usage Tips:

Before installing Plain Cylindrical Bushing Custom Steel Hollow Spacer Sleeve with One-End Chamfer for Shaft Support, always check both the shaft OD and the housing bore ID – wipe off any grit, rust, or burrs with a clean rag or a fine stone. A dirty bore is the quickest way to damage the chamfer or bind the sleeve before it’s seated. For press-fit applications, use a press or a soft-faced hammer with a drift that contacts the full face – never hammer directly on the chamfered edge unless you want it deformed. If the bushing is slightly snug, a thin coat of light machine oil or anti-seize on the OD helps. For slip-fit applications, it should slide in by hand with minimal clearance – if it rattles, your bore is oversize. If the bushing has to carry any thrust load, ensure the plain square end sits fully against the housing shoulder – no gap. Torque or load specs depend on your assembly, not the bushing.
