Factory Direct Supply Coal Mine Pin Shaft
The factory direct supply coal mine pin shaft is a precision-machined component designed for hydraulic support systems in underground mining equipment. It functions as a hinge connection between structural elements such as push rods, side guards, and anti-reverse jacks. The shaft typically features a baffle on one end and a washer with open pin on the other to secure assembly, preventing axial movement under heavy load. These pins are manufactured from high-strength alloy steel, with surface treatments to resist abrasion and corrosion in damp, high-pressure mining environments.
Common variants include fixed pins for static connections, rotary pins for rotating joints in jacks, horizontal pins for scraper conveyor linkages, vertical pins for push rod interfaces, and lock pins for securing side guard plates. Material composition is typically 42CrMo or equivalent, with hardness ranging from 45 to 52 HRC. Surface finish is usually ground to a Ra value of 0.8 micrometers or lower. These specifications align with standard industrial practices for mining hydraulic components, though exact tolerances vary by machine model and manufacturer requirements.
These pin shafts are purchased by coal mining operators, equipment repair shops, and OEMs servicing longwall and face support systems. Buyers typically order in batches of 50 to 500 units depending on maintenance cycles. Packaging is usually in bulk cartons with rust inhibitor coating, shipped via container from Jiaozuo Port. Trade terms are commonly FOB or CIF, with lead times of 20 to 35 days after deposit confirmation. Buyers should confirm dimensional drawings and load ratings for compatibility with their specific hydraulic support models.

Sourcing Factory Direct Supply Coal Mine Pin Shaft from Henan Shuangzhi Machinery Equipment Co., Ltd. - China Import Guide
Before placing an order, verify the pin shaft dimensions against your hydraulic support model's technical drawings. Confirm the material grade and hardness specification, as incorrect values may lead to premature failure under load. Request sample units for fit and function testing before bulk purchase. Ensure the supplier provides batch traceability through part numbering and material certificates.
Lead time is typically 20 to 35 days after deposit. Incoterms are usually FOB Jiaozuo Port or CIF to destination port. Payment terms commonly require 30% deposit with balance against shipping documents. Buyers should confirm container loading capacity per order and request photos of packed goods prior to shipment. Clarify whether packaging meets international shipping standards for heavy machinery parts.
Quality checks should include dimensional verification using calibrated tools, hardness testing with a Rockwell device, and visual inspection for surface defects such as cracks or uneven coating. Request a sample batch for destructive testing if critical to your operations. Ensure the supplier provides a material test report and packing list with each shipment. Retain samples for future quality audits and warranty claims.
