CARBON STEEL SHAFT M4-L10

CARBON STEEL SHAFT M4-L10 is a shaft part made of carbon steel material, with a nominal diameter of M4 (i.e. 4mm diameter) and a length of L10 (i.e. 10mm length). This type of shaft is usually cylindrical in structure, and can also be processed with threads, chamfers, grooves, keyways and other structures as required to meet specific purposes.

M4-L10 is its standard size naming method, M4 represents the diameter of the shaft, and L10 represents the length of the shaft. It may be in the form of a smooth shaft, a threaded shaft, a positioning pin shaft, etc., with different functional properties under different working conditions according to different structures.

Uses:

Precision positioning shaft: used in PCB board connectors and precision electrical equipment to undertake positioning and alignment functions.

Rotation support shaft: used in micro motors, gear transmissions, pulley structures, etc., to support rotating parts.

Mechanical connector: connects two parts to achieve transmission, fixation or structural connection functions.

Motion guide: used in automation equipment with bearings, guide sleeves, etc. to achieve precise linear or rotational motion.

Electronic component support shaft: used as a support element in camera modules, small mechanical structures or consumer electronic products.

Due to its small size, simple structure and strong versatility, carbon steel shafts of M4-L10 size are particularly suitable for space-constrained structural installation environments.

Material:

Carbon steel is an iron-carbon alloy with a high carbon content, good mechanical properties and cost-effectiveness. Types of carbon steel commonly used to manufacture such shafts include:

AISI 1045: medium carbon steel, high strength, good toughness and good machinability.

AISI 1018: low carbon steel, suitable for cold processing, low cost, suitable for occasions with low precision requirements.

C45 (equivalent to 1045): European standard carbon steel, commonly used to manufacture medium-strength parts.

S45C (JIS standard): has good heat treatment characteristics and mechanical properties, suitable for use after quenching and tempering.

Carbon steel shafts usually need to be surface treated before use, such as blackening (phosphating), galvanizing, electroplating nickel, quenching, etc., to enhance their rust resistance, wear resistance and hardness.

Features:

Compact structure: standard size M4 diameter, 10mm length, easy to install in small equipment or precision structure.

Versatile: widely matched with standardized parts such as sliding bearings, fixing clamps, connectors, etc.

Good processability: carbon steel material is suitable for various finishing methods such as turning, milling, grinding, thread cutting, etc.

Wear resistance and pressure resistance: after quenching and tempering or surface hardening treatment, it can have good wear resistance and compressive strength.

Economic and efficient: compared with stainless steel or alloy steel, carbon steel has lower cost and is more suitable for mass production.

Advantages:

High cost performance: on the premise of meeting medium strength requirements, carbon steel has lower material and processing costs and is suitable for large-scale production.

Excellent processing responsiveness: carbon steel shafts are easy to CNC machine and can achieve higher precision requirements.

Good heat treatment ability: mechanical properties can be greatly improved through quenching, tempering, carburizing and other processes.

Widely applicable industries: can be applied to automation equipment, robots, motor components, aircraft models, home appliance assembly, consumer electronics and other fields.

Reliable and stable structure: strong resistance to bending and shearing, suitable for supporting load-bearing parts or precision motion elements.

FAQ:

Is the size of M4-L10 standard? Can other sizes be customized?

M4-L10 is one of the standard shaft sizes, M4 represents a diameter of 4mm, and L10 represents a length of 10mm. If the customer has special size requirements (such as M4-L12, M4-L15, etc.), customization is usually supported. Depending on the application, shafts of different lengths, threads or non-standard structures can also be processed.

Can this type of carbon steel shaft be used in high-speed motors or equipment with large loads?

Carbon steel shafts can be used in medium and low speed or light load applications. If combined with appropriate heat treatment (such as quenching or surface hardening), its performance can be further enhanced. If used in high-speed motors or heavy-load environments, it is recommended to use alloy steel or stainless steel instead to obtain higher fatigue strength and better wear resistance.

Is it rust-proof and suitable for outdoor or humid environments?

Untreated carbon steel is prone to oxidation and rust in a humid environment, so most carbon steel shafts are surface treated (such as galvanizing, nickel plating, blackening, phosphating, etc.) to enhance corrosion resistance. If it is required to be used in a humid environment for a long time, it is recommended to use a stainless steel shaft or add an anti-rust coating.

Has the product passed relevant quality inspections or dimensional control?

Usually, such shafts will undergo dimensional inspections such as outer diameter, length, verticality, tolerance control, etc. before leaving the factory, and provide relevant reports such as RoHS, material certification, hardness testing, etc. according to customer requirements. High-end manufacturers can support full inspection, first-article inspection, and automatic optical inspection.

Are carbon steel shafts easy to stock and transport when purchased in bulk?

Because such shafts are small in size and standardized in structure, they are easy to pack in bulk and manage in warehousing. During transportation, attention should be paid to moisture-proof and rust-proof treatment, such as adding anti-rust oil, desiccant or vacuum packaging. Most suppliers can provide customized packaging services according to customer requirements.
