Product Overview

The W-3825NPS is a metal frame roller rail with ABS roller wheels, 38 mm diameter and 24.5 mm width, rated for 20 kg per wheel. It features a galvanized steel frame with a 45 mm pitch and a track height of 45 mm. The unit is designed for smooth, low-noise operation and can support up to 60 kg per meter. It is suitable for use in gravity roller conveyors and transfer points where consistent load distribution and low rolling resistance are required.

Part of the Ball Transfer Unit range, used in Sheet Metal and Press Shops.

Key Benefits

  • 20 kg load capacity per roller wheel with a 60 kg per meter total load rating
  • Galvanized steel frame resists rust and supports long-term use in industrial environments
  • Low noise and smooth running due to ABS roller wheels and precise shaft alignment
  • 45 mm pitch allows consistent spacing for even load distribution across the track
  • Lightweight frame reduces deck load and simplifies installation and handling

Application Scenarios

  • Gravity roller conveyors in warehouse picking lines where items are moved by hand
  • Transfer points between two conveyor lines with different orientations
  • Assembly line sections where parts are pushed along a flat track without powered drive
  • Material handling systems in cold storage where operation at minus 40 degrees is required
  • Light-duty sorting and routing systems in packaging and logistics facilities

Who It Is For

  • Conveyor system integrators building gravity roller sections with consistent load ratings
  • Material handling equipment builders needing a reliable roller rail for transfer decks
  • Industrial distributors stocking roller rails by load capacity and frame size
  • Production line builders integrating low-friction tracks into manual assembly stations
  • Logistics automation contractors designing low-cost, low-maintenance transfer systems

Problems It Solves

  • Inconsistent load distribution when using mismatched roller sizes or pitches
  • High rolling resistance that slows manual movement of light to medium loads
  • Rust and corrosion in humid or washdown environments due to non-galvanized frames
  • Noise and vibration from poorly aligned or loose roller wheels
  • Difficulty in maintaining consistent track height across multiple units

Technical Features

  • ABS roller wheels with 38 mm diameter and 24.5 mm width for smooth, quiet operation
  • 45 mm pitch between roller wheels ensures even load transfer and alignment
  • Galvanized steel frame with 44 mm width, 32 mm height and 1 mm thickness for durability
  • Roller track height of 45 mm matches standard conveyor deck profiles
  • Shaft size of 3.5 mm x 40 mm provides stable support for the roller wheel

Materials

  • ABS roller wheels for low noise and smooth rolling under light to medium loads
  • Galvanized steel frame for resistance to rust and corrosion in humid or wet environments
  • 3.5 mm x 40 mm carbon steel shaft for stable support and alignment of the roller wheel

Quality Control

  • Roller wheel rotation checked by hand to ensure free movement and no binding
  • Frame dimensions verified against the 44 mm width, 32 mm height and 1 mm thickness
  • Load capacity tested per wheel to confirm 20 kg rating under static load
  • Galvanization layer inspected for even coating and no exposed steel
  • Track height measured across multiple units to ensure consistent alignment

Customization Options

  • Roller wheel color available in yellow, white or black
  • Frame size and pitch available in other models for different load and space requirements
  • Other roller wheel materials such as PE or HIPS available in similar models
  • Length available in customized sizes to fit specific conveyor deck dimensions

Use Guide

  • Ensure the frame is mounted on a flat, level surface to maintain consistent track height
  • Distribute the load evenly across multiple roller wheels to stay within the 20 kg per wheel limit
  • Use only the recommended roller wheel colors for visibility or safety in the work environment
  • Install brake plates at low ends if needed to stop rolling items at the end of the track
  • Use separation boards or guard-side wheels to prevent items from shifting between lanes

Manufacturing Process

Step 1

Machining of the galvanized steel frame to precise dimensions

Step 2

Assembly of the ABS roller wheel onto the carbon steel shaft

Step 3

Insertion of the shaft into the frame with proper alignment

Step 4

Final inspection of roller rotation and track height consistency

Step 5

Packaging for shipment with protective wrapping to prevent damage

Compared With Other Options

Non-galvanized steel frame railsThe galvanized frame resists rust and is better suited for humid or washdown environments
Smaller diameter roller wheelsThe 38 mm diameter offers better load distribution and lower rolling resistance than 28 mm or 30 mm wheels
Fixed pitch rails with no adjustmentThe 45 mm pitch ensures consistent spacing, but other models offer different pitches for specific load or speed needs
