Quick Answer
These sorting machine rubber rollers are available in 140 mm and 85 mm lengths. Both versions have a Ø36 mm natural rubber outer layer, a Ø28 ±0.05 mm 6061 aluminum tube core and a Ø20 mm through bore. The specified rubber hardness is 64–68 Shore A. Custom dimensions can be reviewed according to your equipment drawing.
Product Overview
Sorting machine rubber rollers are cylindrical rubber-covered components designed for industrial sorting equipment. The supplied drawing shows two length options: 140 mm and 85 mm. Both rollers have a Ø36 mm outer diameter and a 6061 aluminum tube core with a Ø28 ±0.05 mm outer diameter. The central through bore is Ø20 mm. Each end includes a Ø22 mm recess with a 9 mm depth. The natural rubber outer layer has a specified hardness of 64–68 Shore A and a nominal thickness of 4 mm. These rollers can be installed in sorting machine assemblies where the cylindrical rubber surface supports contact, guidance or material movement. Buyers should confirm the shaft interface, operating speed, load and contact conditions before ordering.

Applications
These sorting machine rubber rollers are designed for cylindrical roller positions in industrial sorting equipment. The natural rubber outer layer provides a compliant contact surface for applications involving guidance, support or controlled movement of parts and materials. The 6061 aluminum tube core provides an internal structure for the shaft interface. The long and short versions can be used in different positions within the same equipment assembly when the installation layout requires different roller lengths. Buyers should confirm the shaft dimensions, mounting method, operating speed, load, contact surface, duty cycle and exposure to dust, moisture, oil or other media before production.
Customization Options
Custom sorting machine rubber rollers can be reviewed according to a 2D drawing, 3D model or physical sample. Buyers can specify the roller length, outer diameter, rubber compound, Shore A hardness, aluminum tube grade, tube diameter, bore diameter, end recess dimensions, dimensional tolerance and packaging method. Material selection depends on the application conditions. For an accurate quotation, please provide the sorting machine model, installation position, shaft dimensions, operating speed, applied load, contact material, temperature range, required quantity and estimated annual demand. Tooling cost depends on the drawing and product structure.

FAQ
What sizes are available for these sorting machine rubber rollers?
The supplied drawing shows two roller lengths: 140 mm and 85 mm. Both models have a Ø36 mm outer diameter, a Ø28 ±0.05 mm aluminum tube outer diameter and a Ø20 mm through bore. Each end also includes a Ø22 mm recess with a 9 mm depth.
What rubber material and hardness are used?
The specified outer layer is natural rubber with a hardness of 64–68 Shore A. This hardness range should still be reviewed against the actual sorting machine application, including operating speed, load, contact surface, duty cycle and environmental exposure.
What material is used for the roller core?
The internal tube core is specified as 6061 aluminum. The aluminum tube has a Ø28 ±0.05 mm outer diameter and a Ø20 mm through bore. Buyers should confirm the shaft and mounting interface dimensions before placing an order.
Can the roller length and bore size be customized?
Custom dimensions can be reviewed according to your 2D drawing, 3D model or physical sample. Please provide the required length, outer diameter, bore diameter, end recess geometry, tolerances and installation method so that the roller structure can be evaluated.
Are samples available for testing?
Sample availability depends on the roller dimensions, rubber compound, hardness, aluminum tube specification, tooling status and quantity. Please send your drawing or physical sample for review. A prototype sample plan can be confirmed after the technical details are checked.
How is the lead time confirmed?
The lead time is confirmed after reviewing the dimensions, rubber compound, aluminum tube requirements, tooling status, order quantity and inspection requirements. Please provide your target delivery schedule and estimated annual volume when requesting a quotation.
