Poly V Roller Bearings
Plastic poly-V and multi-belt end caps with shaft diameters of 12mm or 15mm, designed for conveyor rollers that use 50mm or 60mm diameter tubes and require a fixed shaft for belt or chain drive alignment.
Problems It Solves
- Mismatched end caps that do not fit the tube diameter or shaft size of existing roller assemblies
- Belt or chain misalignment due to inconsistent end cap geometry on roller units
- Need for a single supplier to provide both end caps and bearings that match a specific shaft and tube size
- Rollers with non-standard shafts that cannot be replaced using generic components
- Assembly delays caused by sourcing end caps from multiple suppliers with varying dimensions
Who It Is For
- Conveyor system integrators building roller conveyors with poly-V or multi-belt drive systems
- Material handling equipment builders requiring end caps that match specific tube and shaft sizes
- Industrial distributors stocking end caps by shaft diameter and tube size for quick replacement
- Production line builders replacing worn or damaged end caps on existing roller assemblies
- Warehouse automation contractors maintaining consistent roller performance across multiple lines
Why This Range
- Four product variants with shaft sizes of 12mm or 15mm and tube sizes of 50mm or 60mm
- End caps available in poly-V and multi-belt configurations for belt or chain drive systems
- Bearing types 6804*2 and 6002*2 used in the end cap assemblies for consistent load support
- Shaft material specified as Nylon6 or Nylon66 for wear resistance and low friction
- Fixed shaft diameter ensures alignment with existing roller shafts and drive components
Application Scenarios
- Replacing end caps on a roller conveyor line where the original shaft size is 15mm and tube is 50mm
- Building a new poly-V belt drive conveyor using 60mm tube rollers with 12mm shafts
- Repairing a multi-belt end cap on a roller that has worn bearings and needs a matched replacement
- Rebuilding a roller assembly with a 50mm tube and 15mm shaft using a plastic end cap with 6804*2 bearings
- Matching end caps across multiple roller units in a line to ensure consistent belt tracking

Poly V Roller Bearings Questions
What tube diameters do these end caps fit?
The end caps are designed for 50mm or 60mm diameter tubes, with specific models matching each size.
What shaft sizes are available?
Available shaft diameters are 12mm and 15mm, with corresponding end cap models for each.
Which bearings are used in the end caps?
The bearings used are 6804*2 for 15mm shafts and 6002*2 for 12mm shafts, depending on the model.
Are the end caps made from plastic?
Yes, the end caps are made from Nylon6 or Nylon66, depending on the model, for durability and low friction.
Can I use these end caps on both poly-V and multi-belt systems?
Yes, there are separate models for poly-V and multi-belt configurations, each with matching sprocket types.
Do the end caps include the shaft?
Yes, the shaft is included as part of the end cap assembly, with a fixed diameter of 12mm or 15mm.
How do I choose between the 50*1.2-15 and 50*1.5-15 models?
The difference lies in the tube wall thickness and bearing fit; select based on the exact tube and bearing specifications of the existing roller.
