DIN 1 Precision Cylindrical Pin 40Cr Polished Locating Pin
Keywords:
DIN1 cylindrical pin, solid locating pin, 40Cr parallel pin, polished straight pin, mechanical positioning pin
Overview
DIN 1 precision solid cylindrical pin is a standardized rigid locating fastener in accordance with German industrial standards. With an integrated solid structure, it provides ultra-high rigidity, stable positioning and excellent repeat assembly accuracy, effectively ensuring precise alignment and firm connection between mechanical parts. Both ends adopt smooth spherical design with consistent radian, which avoids assembly jamming and stress concentration, enabling quick press-in installation and tight fit. With reliable mechanical performance and high dimensional consistency, it serves as an essential core component for mechanical positioning, fixture calibration and daily equipment assembly.
Material & Surface Treatment
All DIN 1 solid cylindrical pins are made of premium 40Cr alloy steel with no heat treatment required. Adopting professional precision polishing technology, the product retains the original natural steel finish without any additional coating treatment. The whole surface is evenly coated with anti-rust oil for long-term oxidation resistance and corrosion protection. Strict fine machining ensures uniformly smooth spherical ends with consistent radian on both sides, no obvious tool marks, burrs or scratches on the entire surface, fully meeting standard precision mechanical assembly requirements.
Application
DIN 1 40Cr solid cylindrical pins are widely used for precise positioning, alignment and fixing in general mechanical equipment, mold structures, jigs and fixtures, automation devices, instrument machinery and automotive tooling, suitable for various conventional precision assembly scenarios without high hardness requirements.
| Standard Precision | Strictly manufactured per DIN 1 German standard with precise dimensional tolerance and excellent straightness, compatible with global universal mechanical assembly standards. |
| Stable 40Cr Performance | High-quality 40Cr alloy steel features fine toughness and stable structural strength, no heat treatment needed for stable daily positioning use. |
| Dual Spherical End Design | Both ends adopt smooth spherical structure with consistent radian, ensuring smooth assembly, no jamming and uniform stress bearing. |
| Exquisite Surface Craft | Precision polished natural finish, no obvious tool marks or burrs on the surface, neat appearance and high fitting accuracy. |
| Long-Term Anti-Rust | Professional oil coating anti-rust treatment isolates air oxidation, maintaining smooth surface and stable performance during storage and long-term service. |

Frequently Asked Questions
product
What core advantages does standard DIN471 external circlip have over non-standard snap rings?
Produced per DIN471 & EN10132-4, it features precise dimension matching standard grooves. Made of 65Mn/C67S, it delivers outstanding anti-fatigue performance and resists loosening under long-term vibration.
How to maintain DIN472 when elastic weakness appears during equipment inspection?
Fatigued circlip cannot be restored; replace with brand-new DIN472 and forbid repeated usage of deformed old parts.
Standard installation operation of DIN6799 circlip?
Align E opening with shaft groove and press down vertically with flat screwdriver until fully seated.
Benefit of phosphated surface for DIN2093 during component service?
Phosphating improves rust and wear resistance to extend service life of DIN2093 inside hydraulic cylinders and high-pressure valves.
Self-locking fixing principle of DIN1481 slotted spring pin?
Slotted body shrinks during pressing and rebounds to expand against hole wall, forming radial preload for self-lock positioning.
business
How to select material of ISO8752 reasonably for different working environments?
Choose 65Mn black oxide carbon steel for dry indoor machinery, auto chassis and general reducer; switch to stainless steel ISO8752 for damp, oily and corrosive working conditions like water pumps and food equipment.
Correct disassembly method for DIN1 during mould maintenance?
Eject DIN1 from opposite end via pin punch; violent hammering is forbidden to avoid bore deformation.
Solution for stuck DIN7 taper pin during equipment overhaul?
Knock out from big end; drill and replace new DIN7 if severely rust locked.
Heat treated quenched steel strip includes blued strip and polished strip, what are respective advantages of two surface types?
All heat treated quenched steel strip is fully quenched with high hardness and stable elasticity. Blued steel strip forms uniform blue oxide layer for natural rust resistance with high cost performance; polished steel
What are the core advantages of annealed steel strip compared with semi-hard strip and heat treated quenched steel strip?
Made from 65Mn, C67S and other spring steel grades, annealed steel strip gets full full-annealing stress relief treatment. It owns the best ductility among three types of steel strips, hardly cracking during bending,
