POM End Caps Matched To Your Conveyor Roller Tube
The end of a conveyor roller brings together a tube, a bearing arrangement and a shaft. A custom molded end cap connects these interfaces within the available end space. This POM component is made to the customer's roller design, with its insertion skirt, flange and central features defined as one coordinated geometry.
Measure The Tube At The Actual Fit Location
The nominal roller outside diameter alone is insufficient for an end cap quotation. The insertion skirt mates with the tube interior, so the inside diameter, wall thickness, roundness and any weld seam need to be considered. Provide measurements or a sample from the tube specification intended for production. The entry chamfer and insertion length should also be shown.
A locating flange can establish the installed depth and cover the tube edge. Its thickness affects the roller's overall assembly length and clearance to adjacent structure. Where an interference fit is proposed, installation force and tube variation must be assessed together. The fit should retain the cap without damaging its hub or distorting the roller tube.
Define What The Central Feature Must Locate
A recessed pocket may locate a separately specified bearing, while a smaller opening provides shaft clearance. The bearing designation, required seat depth and shoulder geometry are therefore useful inputs. A cap designed as a plain sleeve interface needs a different specification from a cap intended to receive a rolling bearing. These alternatives should not be treated as interchangeable.
Mark the relationship between the bearing seat and the tube-locating surface on the drawing. Radial runout, shoulder squareness and axial location are considered at assembly level. A neat-looking molded opening does not by itself establish the running accuracy of the finished roller. Bearing seals, spacers and shaft retention are included only if the agreed component scope requires them.
Balance Rib Support And Molded Geometry
The representative end cap uses a central hub with radial webs inside an outer skirt. These features can support the hub while avoiding an unnecessarily solid section. Rib thickness, transitions and the flange connection are reviewed for molding feasibility. Tooling review also identifies the surfaces where gate vestige, parting lines or ejector marks could interfere with tube insertion or bearing seating.
Any rib, slot or retention detail must remain compatible with the chosen tube and installation direction. The illustrated configuration is a custom design example rather than a stocked cap size. Final dimensions and the number of ribs follow the approved model and sample.
Choose The Acetal Grade And Acceptance Conditions
POM grade selection follows the mechanical, environmental and processing requirements of the application. Supply operating temperature, anticipated cleaning exposure and any specified resin restrictions. A general acetal description does not establish suitability for all chemicals, food contact or electrical requirements. Special grades and supporting documentation are reviewed when required.
Long-term loading and temperature can affect a polymer fit. Where the cap supports a bearing or relies on interference for retention, define the relevant load and operating conditions for evaluation. No universal load capacity, maximum speed or maintenance interval is claimed for the catalogue geometry.
Information Needed For A Useful Quotation
- STP, STEP or IGS model with a dimensioned end-cap drawing.
- Tube inside diameter range, wall specification and mating sample if available.
- Bearing and shaft details, axial stack and intended assembly sequence.
- Critical fits, runout requirements and the agreed measurement method.
- Estimated quantities, color and operating environment.
Sample approval should include insertion behavior, seating depth, bearing installation and assembled rotation. Where required, the finished roller is assessed under the defined load and speed for cap movement, running accuracy and temperature behavior. The complete conveyor arrangement determines the relevant test conditions.
