Part of the Roller bearings with Hex Shaft range, used in Warehouse and Distribution Centres.

Key Benefits

  • Matches tube diameters of 50 mm, 50.6 mm, and 50.8 mm for direct fit on existing rollers
  • Hex shaft provides positive drive connection to prevent slippage under load
  • Metal housing ensures strength and long life in heavy-duty conveying environments
  • Pre-precision bearings allow smooth, free-running operation with low friction
  • Available in multiple shaft size variants to match specific roller shaft requirements

Application Scenarios

  • Gravity roller conveyors in warehouse loading and unloading areas where consistent shaft fit is needed
  • Assembly lines using gravity rollers with hex shaft drive for alignment and positioning
  • Medium to heavy weight conveying in engine or mould manufacturing where drive stability matters
  • Conveyor sections requiring positive drive transfer between rollers without belt or chain
  • Integration into sprocket rollers, O-belt rollers, or poly-V rollers where hex shafts are standard

Who It Is For

  • Conveyor system integrators building gravity roller lines with specific shaft requirements
  • Material handling equipment builders sourcing consistent roller bearings for production
  • Industrial distributors stocking roller bearings by shaft size and tube diameter
  • Manufacturers of gravity rollers needing reliable, matched components for assembly

Problems It Solves

  • Mismatched shaft sizes that prevent secure mounting on standard roller tubes
  • Slippage or misalignment in drive systems due to round shafts under load
  • Inconsistent bearing fit across multiple roller units in a single conveyor line
  • Need for custom machining when standard bearings do not match existing shaft dimensions
  • Reliance on multiple suppliers for bearings, shafts, and tube compatibility

Technical Features

  • Designed for tube diameters of 50 mm, 50.6 mm, and 50.8 mm
  • Hex shaft configuration for positive drive transfer
  • Metal housing for strength and long service life
  • Pre-precision bearings for smooth, low-friction rotation
  • Available in multiple shaft size variants to match specific roller designs

Materials

  • Metal housing for high strength and resistance to impact and wear
  • Precision bearings integrated into the housing for consistent rotation
  • Hex shaft made from durable metal to maintain drive integrity under load

Quality Control

  • Shaft size and hex dimensions verified against the model specification
  • Rotation checked by hand to confirm free movement without binding
  • Tube diameter compatibility confirmed before final packaging
  • Housing integrity checked for cracks or deformation

Customization Options

  • Special bore sizes available upon request for large volume orders
  • Shaft length or hex size can be adjusted based on customer requirements
  • Alternative shaft materials or surface treatments available for specific environments

Use Guide

  • Confirm tube diameter matches the bearing model before installation
  • Ensure hex shaft size matches the drive component or roller shaft
  • Check that the 11 mm shaft length fits within the roller housing depth
  • Use the correct torque when mounting to avoid shaft deformation
  • Inspect for binding or misalignment after installation to ensure smooth rotation
