Product Overview

The GA-01-04 is a plastic roller wheel with a metal bearing, designed for light to medium load handling in material handling systems. It has a 38 mm diameter, 12 mm width, and an 8.1 mm shaft bore, with a maximum load capacity of 30 kg per unit. The wheel is mounted on a carbon steel shaft and features a rubber tread for smooth rolling and grip on flat surfaces. It is suitable for use in conveyors, trolleys, and movable equipment where low friction and easy assembly are required.

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

Key Benefits

  • 30 kg maximum load capacity per unit for light to medium items
  • 38 mm diameter and 12 mm width for consistent fit on standard shafts
  • 8.1 mm shaft bore matches M8 mm shafts commonly used in conveyor systems
  • Rubber tread provides grip and reduces noise during rolling
  • Carbon steel shaft ensures durability under repeated use
  • Easy to assemble and replace in conveyor or trolley applications
  • Plastic body reduces weight and shipping cost compared to all-metal wheels

Application Scenarios

  • Conveyor systems moving small trays or flat packaging in warehouse environments
  • Trolleys and carts used in assembly lines for transporting light components
  • Adjustable workstations where the roller wheel supports movable platforms
  • Floor-mounted guide rails or support wheels in automated handling equipment
  • Light-duty transfer points between conveyor sections where low resistance is needed

Who It Is For

  • Conveyor system integrators building light-duty conveyors for small parts
  • Warehouse equipment builders designing trolleys and mobile racks
  • Industrial distributors stocking roller wheels by shaft size and load rating
  • Assembly line builders needing low-friction wheels for work-in-progress carts
  • Material handling equipment makers integrating wheels into movable fixtures

Problems It Solves

  • Inconsistent roller fit on standard M8 shafts due to mismatched bore sizes
  • High friction or uneven rolling from poorly aligned or low-quality wheels
  • Frequent replacement of plastic wheels that wear out quickly under load
  • Difficulty in mounting wheels that require special tools or press fits
  • Lack of a single source for plastic wheels with known load capacity and shaft compatibility

Technical Features

  • Plastic roller body with integrated metal bearing for smooth rotation
  • Rubber tread on the outer surface for better grip and quieter operation
  • Shaft bore of 8.1 mm designed to fit M8 mm shafts with minimal clearance
  • 38 mm diameter and 12 mm width ensure compatibility with standard conveyor frames
  • Carbon steel shaft provides strength and resistance to bending under load
  • Low weight of 40 g per unit reduces overall system weight and shipping cost
  • No internal seals or lubrication required, suitable for dry environments

Materials

  • Plastic roller body for lightweight and low-cost construction
  • Carbon steel shaft for strength and shaft alignment
  • Rubber tread for improved traction and reduced noise

Quality Control

  • Shaft bore checked against 8.1 mm tolerance to ensure M8 shaft fit
  • Load capacity tested to 30 kg to verify maximum rating
  • Rotation checked by hand for smoothness and absence of binding
  • Material grade confirmed against carbon steel shaft and rubber tread

Customization Options

  • Available in different shaft diameters if the M8 mm size is not suitable
  • Tread material can be changed if rubber is not suitable for the application
  • Other model numbers in the GA-01 series available for different load or size requirements

Use Guide

  • Ensure the shaft diameter is M8 mm to match the 8.1 mm bore
  • Do not exceed 30 kg per wheel to avoid premature wear or failure
  • Use only on flat, smooth surfaces such as trays or rigid packaging
  • Avoid use on soft or uneven surfaces like cloth-wrapped items
  • Inspect regularly for wear on the rubber tread and shaft alignment
