Swing Jaw

Swing Jaw
Details:
The swing jaw is the structural casting behind the jaw plate — not the liner itself. This component carries the eccentric shaft through four roller bearing positions and integrates the toggle seat, making it the load-bearing core of every crushing cycle. When jaw plate wear patterns repeat across consecutive liner sets, or bearing replacement fails to restore crusher performance, the swing jaw body is the component under examination.

Plan Your Next Major Overhaul Around the Swing Jaw Body

 

product-1200-675

Jaw crusher overhauls run on a predictable cycle - jaw plates, toggle plates, bearings. The swing jaw body (Part No. 3102130101) is the component that breaks that cycle when bore geometry or toggle seat interface drifts out of tolerance across multiple liner sets. This page covers overhaul timing indicators, incoming inspection protocol, and overhaul kit configuration for the PEV130 and compatible platforms.

Overhaul Timing: When to Include the Swing Jaw Body

 

 

 

Inspect the swing jaw body at every second or third jaw plate change. Add it to the overhaul order when any of the following is confirmed:

product-1200-675

Jaw Plate Wear Is Asymmetric And Repeating

If the same wear pattern reproduces across consecutive liner sets - heavier on one side, or concentrated in a fixed zone - the cause is bore geometry deviation in the swing jaw body, not the jaw plate itself. Replacing the liner without addressing the casting will replicate the pattern on the next set.

Bearing Runout Persists After A Bearing Change

Bearing runout that returns within one liner set after a confirmed bearing replacement indicates the bore wall is no longer holding the bearing in correct alignment. The deviation is in the casting, not the bearing. A second bearing change will produce the same result.

Toggle Seat Contact Shows Deformation

The toggle seat interface transfers thrust load on every crushing stroke. Deformation at the contact zone causes erratic discharge setting and accelerates toggle plate wear. If the toggle seat shows uneven contact marks or surface deformation after normal liner intervals, the swing jaw body requires dimensional inspection before the next overhaul cycle.

Third Or Fourth Liner Set Reproduces The Same Failure

Repeated failure across three or more consecutive liner sets is the clearest indicator that the swing jaw body is the root cause. At this point, continued liner replacement without a dimensional check on the casting is not a maintenance strategy - it is deferred structural repair at increasing cost per cycle.

 

Incoming Inspection: What to Verify on Delivery

 

Each Horbon swing jaw body ships with quality documentation. On receipt, verify the following against the supplied reports before installation:

 

 

Spectral analysis report (heat/batch number referenced)

Cross-check the batch number on the report against the casting mark. Alloy grade should match your OEM material requirement before installation.

 
 

HRC hardness records

Confirm that hardness readings fall within the specified range at the documented test positions. Any reading outside the range at a bearing seat zone should be flagged before pressing bearings.

 
 

CMM dimensional report

Four bearing seat bore diameters and the toggle seat contact dimensions are listed with actual measured values against nominal tolerance. Verify all four bore readings fall within the C3 fitment band (pre-mount radial clearance 0.340–0.450 mm) before pressing bearings.

 
 

NDT flaw detection certificate

Confirm no subsurface voids or cracks were detected prior to dispatch. If your site requires third-party NDT, specify this at order stage - Horbon supports independent inspection before shipment.

Jaw Crusher Overhaul Kit

 

product-800-800

For major overhaul cycles, Horbon supplies Part No. 3102130101 as part of a complete Jaw Crusher Overhaul Kit:

  • Swing Jaw Body - Part No. 3102130101
  • Movable Jaw Plate - Part No. 3102130100
  • Toggle Seat - Part No. 3102130012
  • Roller Bearings ×4 (C3-class, pre-mount clearance 0.340–0.450 mm)
  • Labyrinth Seals + Grease Nipples

 

Ordering components individually across multiple overhaul cycles introduces dimensional interface risk - bearing seats machined to one casting's tolerance may not align with a toggle seat sourced separately. The overhaul kit ships as a pre-confirmed dimensional set: all interfaces verified against the same drawing revision before production begins.

FAQ

 

Q1: How often should the swing jaw be inspected during routine jaw crusher maintenance?

Inspect at every second or third jaw plate change. A swing jaw body operating beyond three liner sets without a dimensional check is the most common cause of repeated failure patterns that liner replacement alone cannot resolve.

Q2: How is dimensional compatibility confirmed across all components in the Overhaul Kit?

Before production begins, Horbon's engineering team verifies that bearing seat bore tolerances, toggle seat interface dimensions, and jaw plate mounting geometry are all confirmed against the same drawing revision. Components are not sourced or produced independently - the kit is treated as a single dimensional set.

Q3: What documents should I verify before installing the swing jaw body on site?

Verify four items before installation: the spectral analysis report (batch number matches casting), HRC hardness records (readings within specified range at bearing seat zones), CMM dimensional report (all four bore readings within C3 fitment band), and NDT certificate (no subsurface voids or cracks detected). These ship with every unit.

Q4: If our site does not have CMM equipment, how do we verify bore tolerance before installation?

Request the CMM dimensional report issued by Horbon at dispatch - it lists actual measured values for all four bearing seat bores against nominal tolerance. If independent verification is required, specify third-party CMM inspection at order stage. Horbon supports pre-shipment inspection by independent agencies.
