Product Description
・ Product type: Urethane Molded Rollers with Bearings
・ Roller outer diameter [mm]: 25, 30, 35, 40, 50
・ Roller length [mm]: 20, 30, 40, 50, 100
・ Core material: Stainless Steel, Aluminum
・ Urethane Hardness (Color): Shore A90 (Green), Shore A70 (Black)
・ Urethane molded rollers contain 2 pieces of bearing.
・ Roller with Urethane Layer is crafted by sintering urethane onto the core material, creating a high-adhesion coating. Perfect for transporting and sliding various workpieces with ease.
・ This is an economy item; The price is cheaper than the MISUMI standard product.
Product Overview of Rollers
Rollers Urethane layer is sintered on the surface of the core material to form a roller with a high-adhesion coating layer, It is suitable for transportation and sliding of various workpieces.
Product Feature of Rollers
Feature 1 : Rollers, Urethane layer is directly sintered on the outer perimeter of the core material and is not easy to fall off.
Feature 2 : Rollers, Based on its excellent mechanical strength and wear resistance, urethane is widely used to prevent the scars and cracks that occur when brittle objects such as glass and acrylic are transported.
Feature 3 : Rollers, Compared with metal rollers, urethane rollers are less likely to transmit vibration and sound.
Feature 4 : Rollers, Urethane has low dust-generating properties.
Feature 5 : Rollers, Hardness can be directly identified by urethane coloring (Green: A90; Black: A70).
Feature 6 : Rollers, MISUMI [economy series bearing] is adopted, which ensures smooth operation and greatly reduces costs.
Feature 7 : Rollers, Using ether type urethane, it is more resistant to hydrolysis than ester-type urethane and has lower environmental requirements, while maintaining higher mechanical strength and abrasion resistance.

Mechanism name: pallet vertical transfer mechanism
Mechanism function:
Lift the workpiece on the conveyor and change the conveying direction.
Role of urethane roller:
To receive the workpiece conveyed by the motor roller. Coated urethane layer protects the workpiece from damage.

Precautions of Rollers
1. Economy series urethane Rollers use ether type urethane, which is resistant to hydrolysis and has lower environmental requirements. However, due to the SUJ2 material of the bearing, it is still necessary to pay attention to rustprevention
2. Rollers has material color is subject to the actual product.
3. (dh) dimensions are not processed because the core material is an extruded pipe. The dimensions are for reference only.
4. If the tolerance is not marked on the dimensional drawing, general tolerance (intermediate) is guaranteed.
