Plastic roller wheel with metal bearing GA-02

The GA-02 is a plastic roller wheel with a metal bearing, designed for light to small product handling. It has a 48 mm diameter, 18 mm width, and an 8.1 mm shaft diameter, with a maximum load capacity of 40 kg per unit. The wheel is mounted on a carbon steel shaft and uses a rubber outer surface for smooth rolling on flat surfaces. It is used in material handling equipment, warehouse systems, and light-duty conveyors where low friction and easy assembly are required.

Product Overview

The GA-02 is a plastic roller wheel with a metal bearing, designed for light to small product handling. It has a 48 mm diameter, 18 mm width, and an 8.1 mm shaft diameter, with a maximum load capacity of 40 kg per unit. The wheel is mounted on a carbon steel shaft and uses a rubber outer surface for smooth rolling on flat surfaces. It is used in material handling equipment, warehouse systems, and light-duty conveyors where low friction and easy assembly are required.

Part of the Plastic Roller Wheel range, used in Conveyor OEMs and System Integrators.

Key Benefits

  • 40 kg maximum load capacity per unit for light to small product handling
  • 48 mm diameter and 18 mm width fit standard conveyor tube sizes
  • 8.1 mm shaft diameter matches common M8 shafts for easy mounting
  • Rubber outer surface provides smooth rolling on flat, smooth surfaces
  • Carbon steel shaft ensures durability under continuous use
  • Plastic body reduces weight and simplifies shipping and assembly

Application Scenarios

  • Light-duty conveyors in warehouse picking stations for small parts
  • Assembly line transfer points where small trays or components are moved
  • Floor-mounted trolleys or carts that need to roll on smooth surfaces
  • Material handling equipment requiring low-friction, low-weight wheels
  • Conveyor systems where multiple wheels are mounted on a single shaft

Who It Is For

  • Conveyor system integrators building light-duty conveyors
  • Material handling equipment builders using wheels for trolleys or platforms
  • Warehouse automation contractors installing low-load transport systems
  • Industrial distributors stocking plastic roller wheels by shaft size and load
  • Production line builders needing easy-to-assemble wheels for small components

Problems It Solves

  • Need for a lightweight wheel that can be easily mounted on a standard shaft
  • Inconsistent wheel performance when using mixed components from multiple suppliers
  • Difficulty in aligning wheels on a shaft due to mismatched shaft diameters
  • High friction or uneven rolling caused by poor bearing or surface quality
  • Lack of a standard plastic roller wheel with metal bearing that matches common shaft sizes

Technical Features

  • Plastic roller wheel with integrated metal bearing for smooth rotation
  • 48 mm diameter and 18 mm width for standard conveyor tube fit
  • 8.1 mm shaft diameter compatible with M8 shafts
  • Rubber outer surface for low rolling resistance on flat surfaces
  • Carbon steel shaft provides strength and wear resistance
  • Maximum load capacity of 40 kg per unit under normal operation

Materials

  • Plastic body for low weight and corrosion resistance
  • Carbon steel shaft for strength and shaft compatibility
  • Rubber outer surface for smooth rolling on flat surfaces
  • Metal bearing for consistent rotation under load

Quality Control

  • Load capacity tested against the 40 kg maximum rating
  • Shaft diameter verified to match 8.1 mm specification
  • Rotation checked by hand for free movement without binding
  • Material grade confirmed against carbon steel and rubber requirements
  • Weight measured to ensure 30 g per unit

Customization Options

  • Shaft diameter can be adjusted if needed to match specific shafts
  • Wheel diameter and width available in other sizes upon request
  • Material options for the outer surface may be available for special applications
  • Bearing type can be changed for higher load or speed requirements

Use Guide

  • Ensure the shaft diameter matches 8.1 mm to avoid misalignment
  • Use only on flat, smooth surfaces such as trays or pallets
  • Do not use on uneven or soft-bottomed items like cloth-wrapped goods
  • Distribute load evenly across multiple wheels to stay within 40 kg per unit
  • Inspect wheels regularly for wear on the rubber surface and bearing
