Problems It Solves

  • Mismatched shaft sizes between roller end caps and shafts in existing conveyor lines
  • Inconsistent load ratings when sourcing bearings from multiple suppliers
  • Rollers that bind or wobble due to poor fit between end cap and shaft
  • Difficulty in replacing worn bearings without redesigning the roller assembly
  • Need for a single supplier to maintain uniformity in roller end cap and bearing specifications

Who It Is For

  • Conveyor system integrators specifying roller end caps and bearings for new lines
  • Material handling equipment builders requiring matched components for roller decks
  • Warehouse and logistics automation contractors replacing worn rollers in existing systems
  • Assembly line builders sourcing consistent roller components for production lines
  • Industrial distributors stocking roller end caps and bearings by shaft size and load rating

Why This Range

  • End caps and bearings designed to match standard tube diameters and shaft sizes
  • Load rating consistent across all models in the series for predictable performance
  • Available in plastic and metal materials for different load and environment requirements
  • Components supplied as a matched set to ensure proper fit and function
  • Catalogue includes shaft size, tube diameter and load rating for each model

Application Scenarios

  • Replacing worn bearings in a gravity roller conveyor without changing the shaft or tube
  • Building a new roller conveyor with consistent end cap and bearing fit across all rollers
  • Upgrading a line with higher load rating bearings while keeping the same shaft and tube size
  • Integrating roller end caps into a custom roller track with precise shaft alignment
  • Maintaining uniform roller performance across multiple sections of a transfer line

Gravity Roller Bearings Questions

How do I select the right gravity roller bearing for my shaft size?

Match the inner diameter of the bearing to the shaft diameter, ensuring the bearing fits snugly without binding.

Can I use plastic bearings with a metal shaft?

Yes, plastic bearings are available for use with metal shafts, especially where low friction or corrosion resistance is needed.

What is the load rating for each bearing model?

Load rating is listed for each model in the catalogue, based on the shaft size and material used.

Are the end caps and bearings supplied as a matched set?

Yes, each model is designed so the end cap and bearing are compatible in size and load rating.

Do you offer bearings for stainless steel shafts?

Yes, bearings are available in materials that match stainless steel shafts for corrosion resistance.

Can I mix different materials in the same conveyor line?

Yes, but ensure the load rating and shaft size are consistent across all units for uniform performance.

How do I know which model fits my existing tube diameter?

Check the outer diameter of the bearing and end cap against the tube diameter in your existing roller.
