Product Overview

The 02WR is a gravity roller with a plastic end cap, designed for use in conveyor systems where low-friction, consistent rotation is required under moderate load. It features a precision bearing housed in a nylon and PP bearing house, with a shaft end tapping option and multiple tube diameter and material choices. The unit is available in several sizes with matching end cap and shaft dimensions, suitable for integration into roller conveyors, transfer points, and loading stations.

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

Key Benefits

  • Precision bearing ensures smooth, low-friction rotation under load
  • Plastic end cap reduces noise and protects the shaft from impact
  • Multiple tube diameters and shaft sizes allow direct fit to existing tube standards
  • Bearing house made of nylon and PP resists wear and supports long service life
  • Available in steel, SUS304, aluminum, and coated tube materials for different environments

Application Scenarios

  • Gravity roller sections in a warehouse conveyor line for moving cartons or small parts
  • Transfer points between two conveyor lines where product must transition smoothly
  • Loading stations where a pallet or crate is pushed by hand onto a roller deck
  • Assembly line feeders where consistent roller rotation reduces operator effort
  • End caps prevent dust and debris from entering the bearing housing during operation

Who It Is For

  • Conveyor system integrators building gravity roller sections with consistent load handling
  • Material handling equipment builders requiring matched roller and end cap dimensions
  • Industrial distributors stocking gravity rollers by tube size and shaft diameter
  • Production line builders integrating rollers into manual or semi-automated workstations

Problems It Solves

  • Rollers that bind or rotate unevenly due to poor bearing fit or end cap misalignment
  • Dust and debris entering the bearing housing through open ends, causing premature wear
  • Mismatched shaft sizes between rollers and existing tube systems during installation
  • Noise from metal-on-metal contact at the end of the roller during operation
  • Inconsistent roller performance when end caps are not designed for the shaft and tube

Technical Features

  • Precision bearing housed in nylon and PP for low friction and wear resistance
  • Plastic end cap prevents contamination and reduces noise at the roller ends
  • Shaft end tapping available on both ends, with dimensions based on tube width
  • Multiple tube diameters and wall thicknesses to match standard tube sizes
  • Bearing house material and tube surface treatment selected to suit the operating environment

Materials

  • Steel tube for general industrial use and high load capacity
  • SUS304 stainless steel tube for corrosive or washdown environments
  • Aluminum tube for lightweight applications and reduced inertia
  • Nylon and PP bearing house for low wear and smooth rotation
  • Plastic end cap to seal the bearing end and reduce noise

Quality Control

  • Bearing rotation checked by hand for free movement and smooth operation
  • End cap aligned and secured to prevent wobble or misalignment
  • Tube diameter and wall thickness verified against the specified size
  • Shaft end tapping checked for correct thread depth and alignment
  • Material grade confirmed against the order specification

Customization Options

  • Choose from multiple tube diameters and wall thicknesses to match existing tube standards
  • Select shaft diameter and tapping option based on the application and mounting method
  • Choose tube material and surface treatment to suit the environment (dry, wet, corrosive)
  • End cap material is fixed as plastic; no alternative material provided
  • Bearing house material is fixed as nylon and PP; no alternative material provided

Use Guide

  • Match the tube diameter and wall thickness to the existing conveyor tube standard
  • Ensure the shaft diameter and tapping match the mounting requirements at both ends
  • Use SUS304 or coated tubes in wet or corrosive environments to prevent rust
  • Keep load within the roller's rated capacity to avoid bearing wear
  • Inspect end caps regularly for damage or debris accumulation

Compared With Other Options

Rollers with metal end capsPlastic end caps reduce noise and protect the shaft from impact, while metal caps are more durable under heavy impact
Rollers without end capsPlastic end caps prevent debris from entering the bearing housing, extending service life
Rollers with standard bearingsPrecision bearings offer smoother rotation and longer life under consistent load compared to standard bearings

Gravity Roller With Plastic End Cap Questions

What is the bearing type used in the 02WR gravity roller?

It uses a precision bearing housed in a nylon and PP bearing house.

Can the end cap be replaced if damaged?

The end cap is fixed as plastic and not designed for replacement; damaged units should be replaced.

What tube materials are available?

Steel, SUS304, and aluminum are available, with options for galvanizing, chrome plating, PU, and rubber coating.

Is the shaft end tapped on both sides?

Yes, the shaft end has tapping on both ends, with dimensions based on the tube width (W).

What is the purpose of the plastic end cap?

It seals the bearing end, reduces noise, and protects the shaft from impact and debris.

Can I use this roller in a washdown environment?

Yes, use SUS304 or coated tubes for resistance to moisture and cleaning agents.
