S45C Arc Support Bracket | Round Shaft & Pipe Holding Seat

This arc support bracket is one-piece CNC machined from solid S45C steel plate. The semi-circular inner arc is designed to hold round shafts and pipes. Two side lugs with mounting holes and top limit shoulders ensure precise positioning. Widely used in material handling fixtures, pipe conveyor lines and robot centering jigs. Tempering treatment delivers high rigidity against heavy load compression.

Core Specs

Application Industry: Pipe conveyor line, shaft material loading fixture, robot centering jig, hydraulic pipe fixing support

Machining Process: S45C steel blanking → tempering heat treatment → gantry milling & semi-circle arc precision machining → drilling → deburr & chamfer → black oxide anti-rust finish

Tolerance Standard: Arc profile tolerance ≤0.02mm; hole position tolerance ≤0.03mm; flatness 0.05mm per meter

Heat Treatment: Tempered S45C, hardness HB220~260 for improved compression resistance

Production Equipment: Gantry machining center, CNC milling machine, heat treatment furnace

Optional Post-processing: Tempering, deburr & chamfer, black oxide, phosphating, surface quenching

Lead Time: Sample order 4~5 working days, bulk order 7~12 working days

Advantages

✅ One-piece solid steel construction ensures high rigidity, no cracking or deformation under heavy pressure

✅ Precisely machined inner arc closely fits the outer circle of pipes and shafts to prevent slipping

✅ Two-side flange with multiple holes for firm installation without vibration

✅ Top stop shoulders restrict lateral movement to maintain centering accuracy

✅ Tempered S45C steel provides wear resistance for long-cycle automated production

Solid milled arc bracket with tight circular fit; tempered high strength for stable pipe and shaft holding.
