Product Description
SS Semi Hollow Cylindrical Pin Round Head Mechanical Ship Component
Stainless steel semi-hollow cylindrical pin with round head pin - Marine mechanical parts and hardware
Application Scenarios in Shipbuilding Industry
Typical Application Scenarios
- Hull structure & deck machinery: Connection and positioning for hatch covers, rudders, hinges, brackets, deck cranes, winches and other movable components
- Ship outfitting parts: Hinges of doors, windows, hatches, handrails, ladders, marine furniture and assembly mechanisms
- Propulsion & steering system: Positioning pins for connecting rods, rocker arms, linkages and transmission components
- Marine piping & valves: Positioning and locking pins for valve actuators, dampers, quick-release clamps and pipe supports
- Offshore & marine equipment: Quick-release pins for life-saving equipment, davits, lifting appliances, container locks and movable modules
- Marine electrical equipment: Positioning pins for electrical cabinets, control consoles, junction boxes and fixed brackets
Core Technical Characteristics
Structural Design Advantages
- Precise positioning: High concentricity and fit clearance, ensuring stable assembly and alignment
- Shear resistance: Mainly bears shear force, suitable for hinged and rotating connections
- Easy installation & disassembly: Can be fitted with cotter pins, circlips or locking grooves for quick assembly
- Stable connection: Prevents radial movement and ensures reliable operation under vibration
Material & Corrosion Resistance
- Main materials: AISI 304, 316, 316L, duplex stainless steel 2205 / 2507
- Excellent corrosion resistance: Resists seawater, salt spray, humidity and marine atmospheric corrosion
- Surface treatment: Passivation, electropolishing, mechanical polishing to improve corrosion resistance and appearance
- Compliance: Meets marine corrosion protection standards and marine classification requirements
Mechanical Performance
- High shear strength: Stable mechanical properties under alternating load and impact
- Good toughness: Resists fracture under ship vibration, wave impact and mechanical shock
- Fatigue resistance: Suitable for long-term dynamic load and repeated opening-closing movements
- Dimensional stability: Small deformation, ensuring long-term fit accuracy
Processing & Standardization
- Customizable: Can be designed with grooves, holes, threads, flats or stepped shafts
- Processing: CNC turning, grinding, heat treatment, precision finishing
- Quality control: Hardness testing, dimensional inspection, salt spray test, ultrasonic inspection if required
- Certification: Can be produced according to marine standards and classification society requirements (CCS, LR, DNV, BV, ABS)
Selection & Installation Guidelines
- Material selection: 316/316L for general marine use; duplex stainless steel for severe corrosion environments
- Fit clearance: Select clearance / transition fit based on working conditions (rotating, positioning, hinging)
- Locking mode: Use circlips, cotter pins, locking nuts or threaded ends to prevent falling off
- Installation: Ensure coaxiality; avoid excessive knocking to prevent deformation or surface damage
