Rubber-coated Rollers with Keyway

Brand :
MISUMI
Caution
Product Description
Product Overview
Polyurethane is sintered onto the outer circumference of the core material to form a high-adhesion coated layer, creating a bearing-type roller suitable for transporting and sliding various workpieces.
Dimensional Drawing
When L ≤ d × 3, the d hole is machined from a single direction.
When L>d × 3, the d hole is machined from both sides, as shown in the diagram above. In some cases, there may be no clearance machining.
There are different machining processes for the keyway, so the appearance of the keyway hole may vary.Specification Overview
Material | Hardness | |||
| Straight Cylindrical | Threaded Hole | Core Material | Lining | |
| E-ROUAK | E-ROUAKN | Aluminum alloy | Polyurethane (green) | Shore A90 |
| E-ROGAK | E-ROGAKN | Polyurethane (black) | Shore A70 | |
Due to previous omissions in translating the hardness unit Shore A, the term 'Xiao's hardness' has now been officially corrected to 'Shore hardness.' Updates to electronic and printed catalogs may be delayed; please refer to the website for the most accurate information.Specification Table

Product Features
Feature 1: The polyurethane layer is directly sintered onto the outer circumference of the core material, making it difficult to peel off.
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.

Precautions
(1) The economical polyurethane roller uses ether-based polyurethane, which is resistant to hydrolysis and can be used in slightly humid environments.
(2) Please refer to the actual product for material color.
(3) For dimensions without specified tolerances in the drawing, general tolerances apply.
