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

Key Benefits

  • Designed for 50 mm or 60 mm tube diameters with 15 mm shaft size
  • Uses precision 6804*2 bearings for smooth, quiet operation
  • Nylon66 housing resists wear and corrosion in washdown and industrial environments
  • Free-running design reduces friction and effort during material transfer
  • Integrated bearing allows for consistent performance across long conveyor runs

Application Scenarios

  • Gravity roller conveyors in warehouse loading and unloading zones
  • Assembly lines in electrical and automotive manufacturing with medium to heavy loads
  • Mould and engine manufacturing lines where quiet operation is required
  • Lightweight conveying systems in food or pharmaceutical environments
  • Conveyor sections where plastic roller bearings are used to avoid marking or damaging product surfaces

Who It Is For

  • Conveyor system integrators building gravity roller lines
  • Material handling equipment builders using plastic roller bearings
  • Industrial distributors stocking plastic end caps by shaft and tube size
  • Manufacturers of poly-V rollers for medium to heavy weight conveying
  • Production line builders needing consistent end cap fit for tube-based rollers

Problems It Solves

  • Mismatched end caps that do not fit standard tube or shaft dimensions
  • Rollers that bind or rotate unevenly due to poor bearing alignment
  • Noise and vibration from loose or low-quality end caps in conveyor systems
  • Inconsistent performance when using mixed or non-standard plastic roller bearings
  • Difficulty in sourcing a single supplier for end caps that match tube diameter and shaft size

Technical Features

  • Housing made from Nylon66 for durability and resistance to moisture and chemicals
  • Precision 6804*2 bearing integrated into the end cap for consistent rotation
  • Designed for 50 mm or 60 mm tube diameters with 15 mm shaft size
  • Bore size matches 15 mm shaft for secure fit and alignment
  • End cap is a complete unit with bearing and housing in one piece

Materials

  • Nylon66 housing for resistance to wear, moisture and chemical exposure
  • 6804*2 precision bearing for smooth, low-friction rotation
  • Plastic housing reduces weight and avoids marking on sensitive surfaces

Quality Control

  • Bearing rotation checked by hand for free movement and no binding
  • Shaft bore diameter verified against 15 mm specification
  • Housing dimensions checked against 50 mm or 60 mm tube size requirements
  • Material grade confirmed as Nylon66 before packing
  • Visual inspection for cracks, flash or misalignment in the housing

Customization Options

  • Special bore sizes available upon request for large volume orders
  • End caps can be supplied for other tube diameters if volume justifies tooling
  • Alternative bearing types may be considered for high-load or high-speed applications
  • Color or marking options available for identification in large orders

Use Guide

  • Verify that the tube diameter matches 50 mm or 60 mm before installation
  • Ensure the shaft is 15 mm in diameter to fit the bore without play
  • Check that the bearing rotates freely before mounting on the roller
  • Use only on gravity rollers or non-powered conveyor sections
  • Avoid overloading beyond the design limits of the bearing and housing
