Sandvik JM1208 Swing Jaw Plate 400.0412-002 — Heavy Duty M2 Moving Jaw for CJ412 Crusher
The Sandvik 400.0412-002 Swing Jaw Plate is the OEM-specification Heavy Duty (HD) M2 alloy moving jaw plate for the Sandvik JM1208 jaw crusher — also known as the CJ412 in Sandvik’s current product nomenclature. This one-piece, reversible wear part forms the active crushing surface on the moving (swing) jaw of the CJ412 / JM1208 single-toggle jaw crusher, directly impacting material reduction efficiency, throughput capacity, and overall crusher productivity across its entire service life.
The Sandvik CJ412 single-toggle jaw crusher is engineered for the toughest applications thanks to its heavy-duty design. Characterized by attention to detail in its design and manufacture, it is an excellent choice when high production and low total cost are required, featuring wedge setting regulation that makes it ideal for mobile applications and operations where demands change quickly.
Part Number & Alloy Identification
Within the CJ412 (JM1208) jaw plate range, part number 400.0412-002 is the Moving (swing) Heavy Duty jaw plate in M2 alloy. Mining Understanding the alloy coding is critical to correct part selection:
- HD (Heavy Duty): A thicker, heavier jaw plate profile engineered to withstand the increased impact and compressive loads generated when crushing highly abrasive or blocky feed materials
- M2 Alloy: Sandvik’s M2 alloy offers high resistance to abrasive rock, making it the preferred choice for highly abrasive feed materials, though it has lower resistance to shock and impact compared to M1. Mining M2 is the optimal selection when abrasion index (AI) is the dominant wear mechanism
Key Features
- OEM Part Number: 400.0412-002 — the exact Sandvik-specified HD M2 moving jaw plate for the JM1208 / CJ412
- Also Known As: Swing Jaw Plate HD M2 1208 — moving jaw wear part for the CJ412 single-toggle jaw crusher
- Heavy Duty (HD) Profile: Increased plate thickness for extended wear life under high-abrasion, high-impact primary crushing conditions
- M2 High-Abrasion Manganese Alloy: M2 alloy offers high resistance to abrasive rock Mining — the correct selection for abrasive granite, basalt, quartzite, and similar hard rock feed materials
- One-Piece Construction: All jaw plates are one piece Mining — no joints or assembly interfaces to loosen, crack, or misalign under crushing load
- Reversible Design: The jaw plate can be turned end-for-end to utilise both wearing faces, effectively doubling the usable wear life per plate and reducing cost per tonne crushed
- Optimised Nip Angle Compatibility: Engineered to maintain the CJ412’s deep symmetrical crushing chamber geometry and optimised nip angle for consistent material flow and size reduction
- Direct OEM Replacement: Matched to factory dimensions and mounting configuration — no modification required for installation

Jaw Plate Selection Guide for the JM1208 / CJ412
Sandvik offers seven teeth patterns and up to three alloy selections (M1, M2, M8) to suit different types of quarrying and mining applications. Patterns include Wide Teeth (WT), Corrugated (C), Coarse Corrugated (CC), Sharp Teeth (ST), Heavy Duty (HD), and Heavy Duty Ultra-Thick (UT). M1 is the standard alloy offering high resistance to shock and impact, while M2 and M8 alloys offer high resistance to abrasive rock but lower resistance to shock and impact. Mining
The 400.0412-002 HD M2 swing jaw plate is the correct selection when your feed material is highly abrasive and the Abrasion Index (AI) is the primary wear driver. For mixed or less abrasive applications, the M1 equivalent (400.0412-001) may offer a better balance of wear and impact resistance.
