Configuration Snapshot

The values above describe the specified configuration for this model. They do not imply undocumented load capacity, material, hardness, life, or compatibility with a specific machine.

Product Overview

K207B belongs to the K Series ladder conveyor chain family used in underground mining material-handling applications. The K Series application scope includes shuttle cars, underground feeder breaker chain conveyors, and coal-washing service. K207B is shown specifically as a feeder breaker scraper chain, which makes it suitable for a dedicated model page rather than a generic mining-chain listing.

Although K207B and K201B share a nominal 3 1/2 inch pitch, their scraper widths and component structures are different. That difference illustrates a common replacement-chain problem: pitch can narrow the search, but it does not define the complete chain. Width, repeating assembly length, link construction, flight/scraper arrangement, and machine interface must also be checked.

For an existing feeder breaker, compare the installed chain with the documented K207B values and component arrangement. If the chain has been modified, repaired with non-original parts, or cannot be positively identified, use a drawing and measured chain rather than relying on the model name alone.

Chain Structure and Components

The specified K207B secondary components are:

• K207B01 – Chain Section
• K207B02 – Outer Link
• K207B03 – Inner Link
• K207B04 – Scraper Outer Link
• K207B05 – Flight Section

The specified tertiary components are:

• K207B001 – Outer Plate A
• K207B002 – Outer Plate B
• K207B003 – Inner Plate
• K207B004 – Bush
• K207B005 – Pin
• K207B006 – Extended Pin
• K207B007 – T-Pin
• K207B008 – Scraper Head
• K207B009 – Scraper Plate

The scraper outer link and extended pin are useful identification details because they appear explicitly in the K207B structure. They should be photographed during an unidentified-chain review. As with K201B, component names on this page describe structure; separate component availability must be confirmed in the quotation.

Dimension and Selection Drawing

Use the dimension view as a reference before comparing an installed chain. Measurement should be taken from safe, accessible reference points and recorded together with photographs showing how the flight and links are arranged.

Technical Specifications

The technical information does not provide model-specific values for material grade, hardness, tensile strength, mass, or a machine compatibility list. Those requirements should therefore be supplied by the customer specification or resolved during technical review.

Underground Feeder Breaker Application

K207B is presented for feeder breaker chain-conveyor service within the K Series underground mining context. For replacement selection, the practical checks are the same ones that control fit and function: pitch, unit length, scraper width, chain arrangement, flight geometry, and the relationship between the chain and existing machine components.

The 46 inch documented scraper width is an important distinction from K201B. If an existing chain is nominally 3.5 inch pitch but its scraper width or flight configuration differs, do not assume K207B is a direct match. Photograph the chain, measure the relevant dimensions, and compare the full configuration.

Selection and Customisation Inputs

For a K207B quotation or replacement review, provide:

• model reference if known;
• pitch measurement and how it was taken;
• chain unit length;
• scraper width;
• photographs of K207B-type chain section and joint areas if available;
• close-ups of the scraper outer link, flight section, pins, scraper head, and scraper plate;
• feeder breaker or conveyor application context;
• drawing or measured sketch when available;
• required quantity and any customer-controlled technical requirements.

Where the measured chain differs from the K207B configuration, the difference should be treated as an engineering question rather than silently corrected to the catalogue dimensions.

Inspection and Maintenance Considerations

Follow the feeder breaker manufacturer’s maintenance procedure and site isolation rules before touching or measuring the chain. Once the system is safely accessible, record the condition of links, plates, pins, bushes, flight sections, scraper components, and visible retention features. Uneven contact, deformation, abnormal side wear, damaged flights, missing retention parts, or repeated adjustment can be evidence that the chain and the surrounding system need a broader inspection.

For tension and wear, avoid relying on universal limits from unrelated equipment. A correct assessment uses the machine-specific adjustment procedure, measured chain condition, sprocket engagement, and the approved chain or machine specification. Photographs and measurement logs are especially valuable when a replacement is planned during a future shutdown.

Read the Wear and Replacement Guide

Manufacturing and Quality Workflow

K Series product information identifies special heat-treated pins as a family feature. Manufacturing review can also cover assembly and inspection requirements for the confirmed order. Those facts support a general manufacturing and quality narrative, but they do not establish a unique K207B heat-treatment recipe or inspection limit.

For a controlled order, the approved drawing and purchase specification should define the requirements that matter: dimensions, component identities, material or treatment requirements when specified, assembly configuration, and inspection or documentation expectations. If a requested performance value is absent from the technical data and customer drawing, it should be resolved before production rather than added as an unsupported website claim.

K207B Identification Checklist

A K207B review should progress from dimensions to structure. Confirm the nominal 3 1/2 inch pitch, the 21 inch repeating chain unit, and the 46 inch scraper width. Then check the model-specific construction, including the documented Scraper Outer Link and the presence of the Extended Pin and T-Pin in the component tree. Those details make the structural comparison stronger than pitch alone.

If an existing chain is believed to be K207B but the scraper width differs, do not round the measurement to 46 inches without measurement support. First confirm the measurement endpoints, inspect an intact flight, and compare the current assembly with the drawing or previous purchase record. A difference can come from measurement technique, wear, repair history, or a genuinely different configuration; the website should not decide among those possibilities without the chain measurements and photographs.

For future repeat procurement, keep the approved drawing and a small set of reference photographs showing the complete flight unit, chain section and joint details. That creates a controlled reference for the next RFQ and helps maintenance and purchasing teams communicate the same configuration.

Identification Record for Repeat Orders

A repeat order is easier to control when the maintenance and purchasing teams preserve the configuration that was actually approved, rather than relying on the model name alone. For K207B, the record should identify the chain as K207B and retain the drawing or approved dimensional reference used for the previous order. The nominal pitch, repeating chain unit length, scraper width, and the characteristic component arrangement should remain together in the same technical file.

Photographs can make that record more useful. Keep one overall image of an intact repeating unit, one view of the chain section and joint, and one view of the flight/scraper connection. If the site has repaired a flight, changed a fastening detail, or replaced a local component, note that history separately so a later reviewer does not mistake a field repair for the original configuration.

When a new enquiry arrives, compare the current dimensions, drawings and photographs with the controlled record. If the dimensions and structure remain consistent, the previous technical reference can support the new quotation. If any important detail differs, route the difference for engineering review instead of assuming that the old drawing still controls.

If the Installed Chain Does Not Match the Reference

A chain can be labelled K207B in a maintenance record while the installed assembly shows a different scraper width, different attachment arrangement, or different joint detail. In that situation, preserve the discrepancy. Record the value from the drawing, the value measured on the chain, the measurement method, and photographs of the reference points. Do not edit the field result to make it agree with the expected model.

The same rule applies to component identity. K207B includes a documented Scraper Outer Link, Extended Pin, T-Pin, Scraper Head, and Scraper Plate in its component tree. If an installed chain lacks a feature that should be present, or shows an attachment that is not represented in the K207B structure, treat the model match as unconfirmed until the evidence is reconciled.

A quotation can still proceed as an engineering review when the model is uncertain. The useful output at that stage is a controlled list of confirmed dimensions, photographs, drawing references, and open questions – not a premature claim that the chain is interchangeable with a standard K207B assembly.
