Double O Groove Roller with Steel End Cap

The Double O Groove Roller with Steel End Cap is a gravity roller with a precision bearing housed in a steel case, designed for use in roller conveyors where consistent tube diameter, shaft size and load rating are required. It features a double O groove profile on the roller body and a steel end cap for durability. The unit is available in multiple tube diameters and lengths, with options for surface treatments including galvanized, chrome plated, and PU or rubber coating. It is intended for use in material handling systems where reliable, low-friction rotation is needed under load.

Part of the Roller range, used in Warehouse and Distribution Centres.

Key Benefits

  • Double O groove profile provides stable product guidance on the roller
  • Precision bearing ensures smooth rotation under load
  • Steel end cap increases durability at the ends of the roller
  • Steel or SUS304 tube material supports heavy-duty applications
  • Surface treatments extend life in corrosive or high-wear environments

Application Scenarios

  • Gravity roller conveyors in warehouse loading and unloading zones
  • Assembly lines where parts are moved by hand or with minimal force
  • Material handling systems requiring consistent roller diameter and shaft size
  • Conveyor sections where product alignment must be maintained over long runs
  • Industrial environments with exposure to moisture or chemicals

Who It Is For

  • Conveyor system integrators building gravity roller sections
  • Material handling equipment builders sourcing matched roller components
  • Industrial distributors stocking rollers by tube diameter and shaft size
  • Production line builders requiring consistent roller profiles
  • Warehouse automation contractors installing roller conveyors with defined dimensions

Problems It Solves

  • Mismatched rollers in a conveyor line due to inconsistent tube diameter or shaft size
  • Rollers that bind or rotate unevenly due to poor bearing or housing quality
  • End caps that break or deform under repeated impact or load
  • Lack of consistent roller dimensions across multiple suppliers
  • Short roller life in wet or corrosive environments without proper surface treatment

Technical Features

  • Double O groove profile on the roller body for consistent product tracking
  • Precision bearing housed in a steel bearing house for long life and smooth rotation
  • Steel end cap for added strength and impact resistance at the roller ends
  • Available with tube materials of steel or SUS304 for different environmental needs
  • Surface treatments including galvanized, chrome plated, PU or rubber coating for wear and corrosion resistance

Materials

  • Steel tube for general industrial use
  • SUS304 tube for improved corrosion resistance
  • Steel end cap for durability at the roller ends
  • Galvanized surface treatment for protection against rust
  • Chrome plated surface for wear resistance in high-contact areas

Quality Control

  • Bearing rotation checked for free movement before final assembly
  • Tube diameter and shaft size verified against the model specification
  • End cap attachment checked for alignment and strength
  • Surface treatment thickness and coverage inspected where applicable
  • Final unit tested for smooth rotation under no load

Customization Options

  • Choose between steel or SUS304 tube material
  • Select surface treatment: galvanized, chrome plated, PU or rubber coating
  • Available in different tube diameters and lengths based on model series
  • End cap material can be specified as steel for standard use
  • Other model numbers in the series available for different dimensions

Use Guide

  • Ensure the roller tube diameter and shaft size match the existing conveyor frame
  • Use the correct surface treatment for the environment (e.g. galvanized for damp areas)
  • Check that the roller length fits within the conveyor frame width
  • Avoid overloading beyond the rated capacity for the tube and bearing
  • Inspect end caps regularly for damage or loosening in high-impact zones
