Jaw Crusher Swing Jaw – Heavy-Duty Replacement Body for PEV130 & Universal Models
Part No. 3102130101 | Factory-Direct from Quzhou Horbon Mining Parts Co., Ltd.
What Is a Jaw Crusher Swing Jaw Body?
In a jaw crusher, the swing jaw is the driven moving component that executes the reciprocating compression cycle against the fixed jaw. While the term is often applied to the wear-facing jaw plate, the structural core behind it - the swing jaw body - is the load-bearing casting that mounts the eccentric shaft bearings, carries the toggle seat, and transmits every crushing force cycle into the frame.
This page covers the jaw crusher swing jaw body (structural casting, Part No. 3102130101), not the replaceable jaw plate. If your eccentric shaft alignment is compromised, your bearing seats are worn, or your swing jaw assembly shows structural fatigue, this is the component that requires replacement.
Horbon manufactures this swing jaw body as a direct OEM-equivalent replacement for the PEV130 jaw crusher, with universal fitment capability across Metso, Sandvik, Terex, Trio, and domestic crusher platforms.

How to Identify Whether You Need a Swing Jaw Body Replacement
Procurement engineers and site maintenance leads often confuse swing jaw body wear with bearing failure or jaw plate wear. The swing jaw body itself requires replacement when:
Bearing seat bore deviation exceeds tolerance
The four roller bearing positions in the swing jaw body are machined to precise bore tolerances. When bore diameter drifts beyond the allowable range due to fretting or impact fatigue, no bearing replacement will restore correct shaft alignment.
Toggle seat contact zone shows deformation
The integrated toggle seat (3102130012) transfers thrust load from the toggle plate into the swing jaw body on every crushing stroke. Deformation at this interface causes erratic discharge setting and accelerated toggle plate wear.
Casting shows propagating cracks near bore walls
Surface cracks away from load zones may be field-repairable. Cracks running into or around bearing bore walls indicate the structural integrity of the swing jaw body is compromised and replacement is the correct intervention.
Swing jaw assembly produces lateral deflection
If dimensional inspection confirms the swing jaw body frame is no longer square, secondary damage to the eccentric shaft and flywheel becomes a measurable risk.
Material & Manufacturing Standard
Horbon produces each jaw crusher swing jaw body using processes validated for continuous high-impact mining duty:
Chromium-Molybdenum Alloy Steel Construction
Selected for superior toughness and fatigue resistance under repeated eccentric shaft loading, compared to standard structural steel grades.
01
Precision CNC Bore Machining
All four bearing seat bores are finish-machined on CNC equipment to maintain the dimensional consistency required for C3-class roller bearing fitment (pre-mount clearance 0.340–0.450 mm).
02
Hardness Verification (HRC Testing)
Each casting undergoes hardness testing before machining to confirm heat treatment depth meets specification.
03
NDT Inspection
Non-destructive testing on every swing jaw body to eliminate subsurface voids or micro-cracks prior to dispatch.
04
Spectral Analysis of Raw Material
Incoming steel is verified by spectrometer before entering production, ensuring alloy composition matches the design specification.
05
Compatibility & Ordering Reference
Before submitting an inquiry, cross-reference your swing jaw body against the following parameters from your original equipment:
Product drawing
| Checkpoint | Reference Value / Action |
|---|---|
| OEM Part Number | 3102130101 (PEV130 reference) |
| Eccentric Shaft Diameter | Confirm against your existing shaft |
| Bearing Bore Count | 4 positions |
| Toggle Seat Interface | Verify against Toggle Plate (Part Ref. 3102130031) |
| Linked Components | Eccentricity Shaft (3102130001), Bearing Housing ×2 (3102070015 / 3102070016) |
| Delivery Requirement | Bare casting or pre-assembled with labyrinth covers |
| Machine Brand | PEV130 / Metso / Sandvik / Terex / Trio / universal domestic |
Buyers without the OEM part number can submit the original machine model, a dimensional drawing, or a photograph of the worn component. Horbon's engineering team will confirm fitment within 24 hours.
