Product Description
Product Overview
A hollow roller suitable for transporting and sliding various workpieces.
Dimensional Drawing

The outer diameter of this product is D+2T. (Different from other rollers.)
The bearing is removable. Tape is used for temporary fixation during shipping.
There are different machining processes for the keyway, so the appearance of the keyway hole may vary.Specification Overview
| Type | Material | Surface Treatment(Coating) | Hardness | |
| Core Material | Bearing | |||
| E-RORLAU | Aluminum alloy | Steel | Polyurethane (green) | Shore A90 |
| E-RORLAG | Polyurethane (black) | Shore A70 | ||
The shaft end and inner diameter sections are not surface treated.
Since the core material is drawn material, the inner diameter d1 may be uneven.Specification Table

The actual product color may vary.
The bearings used in this product are not guaranteed to be of a specific brand.
The end face has been specially machined to avoid contact with the inner ring of the bearing.Product Features
Feature 1: The core material uses drawn profiles, achieving a lightweight design while better controlling the cost.
Feature 2: Compared to metal rollers, polyurethane rollers are less likely to transmit vibration and noise.
Feature 3: Polyurethane has low dust generation.
Feature 4: The hardness can be easily identified by the color of the polyurethane (green: A90; black: A70), and it does not experience the yellowing phenomenon that occurs with natural-colored polyurethane.
Feature 5: The polyurethane is sintered onto the core material surface, which provides higher polyurethane adhesion compared to press-fit or adhesive products, making it more suitable for applications with larger axial loads.

Precautions
(1) Since this is a core material product and is an extruded profile, the d1 inner diameter may be uneven.
(2) The shaft ends and inner diameter sections are not surface treated.
(3) Polyurethane dimensional changes
The size of the polyurethane may change with the surrounding temperature, but the variation is minimal, and it will return to its original size after being left at room temperature for several hours.

Example of Use

Mechanism Name: Gasket Bubble Removal Fixture
Mechanism Function:
The laminated gasket is clamped with a rubber roller to remove air bubbles.
Function of polyurethane tubing:
The polyurethane tubing roller is used to clamp and rotate, pressing the workpiece (laminated gasket). Because the surface is sintered with polyurethane, it prevents scratches on the workpiece surface while enabling displacement of the workpiece and removal of air bubbles by pressing.
