Introduction: Why Are SACMI PCR Steel Belts So Critical?
SACMI PCR (Pressa Continua Rivestita) series continuous roller presses are the core equipment in global ceramic large-format tile production lines. As the core component of Continua+ technology, the SACMI PCR steel belt directly determines pressing quality, production efficiency, and operating costs.
A worn or improperly specified belt can cause: product chipping, uneven thickness, over 30% productivity loss, and costly downtime. Therefore, proper selection and procurement of Continua+ steel belts is a critical technical capability for every ceramic manufacturer.
This guide provides comprehensive analysis of SACMI PCR steel belt technical specifications, selection criteria, and how to achieve cost optimization through professional third-party suppliers.
Technical Principles of SACMI PCR Steel Belts
SACMI PCR uses dual steel belt converging continuous pressing technology. Upper and lower belts are driven by precision roller systems, converging at micro-angles to apply continuous uniform compaction pressure to the powder layer.
Core Technical Requirements for Continua+ Steel Belts
- Material Purity: Must use SUS304 food-grade stainless steel with carbon content ≤0.08%, ensuring no magnetic interference and chemical stability
- Thickness Uniformity: Full belt thickness tolerance controlled within ±0.02mm to avoid uneven compaction pressure
- Surface Finish: Ra value must reach 0.8μm or above to prevent tile surface scratches
- Edge Straightness: Edge straightness error <0.5mm/m for precise fit with side seal strips
- Fatigue Resistance: Must withstand over 20 million cycles without plastic deformation

Comparative Analysis of Four SACMI PCR Steel Belt Models
PCR2000 Steel Belt: The Reliable Choice for Classic Machines
PCR2000 is the foundational model of the Continua+ series with over 2,500 installations globally. Its SACMI PCR steel belt features a 7500mm upper belt with 16,900-30,100mm lower belt, suitable for 900-1600mm pressing width.
Selection points:
- Standard configuration uses 16,900mm lower belt for mainstream 900×1800mm formats
- Recommend 30,100mm extended lower belt for large format production
- Typical replacement cycle: 18-24 months
PCR2120 Steel Belt: Compact & Smart Choice
PCR2120 is positioned as the "smart compact" version with 750-1200mm pressing width and 19,300m²/day capacity. Its steel belt for roller press uses 1200mm width, the most compact Continua+ configuration.
Selection points:
- Ideal for medium-small format tiles and specialty products
- Smaller belt width means lower replacement costs
- Supports 3-20mm thickness range with excellent flexibility
PCR2180 Steel Belt: Flagship for Large Format Era
PCR2180 is SACMI's flagship model for the large format market with 1000-1800mm pressing width and 33,200m²/day capacity. Its ceramic press steel belt uses 1800mm width specification.
Selection points:
- Current market mainstream with most complete spare parts supply
- Supports 1200×2400mm, 1200×2700mm and other large format specifications
- Bears highest compaction pressure; recommend high-strength materials
PCR3000 Steel Belt: Thick Slab Specialist
PCR3000 is the top-tier Continua+ model, designed specifically for 3-30mm thick slabs with 40,000m²/day capacity. Its SACMI PCR steel belt also uses 1800mm width but with a stronger tension system.
Selection points:
- Only model supporting 30mm thick slab compaction
- Higher belt tension requirements with stricter material specifications
- Longer spare parts delivery time; advance stocking recommended
5-Step Method for SACMI PCR Steel Belt Selection
Follow these five steps to ensure you select the best Continua+ steel belt for your production needs:
Step 1: Confirm Model and Belt Position
First, identify your SACMI PCR model (2000/2120/2180/3000), then determine whether you need to replace the upper or lower belt. The upper belt mainly bears compaction pressure while the lower belt承受更大张力和摩擦力。
Step 2: Verify Belt Dimensions
Accurately measure the existing belt's width, length, and thickness. Measure during operation for the most precise data. Note: Lower belt lengths can vary significantly between configurations (16,900mm vs 30,100mm).
Step 3: Assess Operating Conditions
Consider these operational factors:
- Product thickness range (3-20mm or 3-30mm thick slabs)
- Daily capacity targets
- Production of polished or special surface effect products
- Raw material formulation (special abrasive content)
Step 4: Choose Material & Surface Treatment
GDNOS offers two SACMI press parts steel belt options:
- China-Made High-Strength Steel: Excellent value, suitable for standard tile production, fast delivery

Step 5: Evaluate Supplier Services
When selecting a supplier, focus on:
- Welding service availability
- On-site installation guidance
- Spare parts delivery time
- Warranty policy and service response speed
