Long roller, shaft length approx. 1070mm, continuous shaft, equipped with NSK 6004DU

■ Product Overview
This is a long roller.
The material details are unknown, but it has an elastic rubber-like surface, possibly urethane-based based on its appearance and feel.
The shaft is a single 20mm steel through-shaft.
Length: Approx. 1070mm, Roller Width: Approx. 950mm
Outer Diameter (Pulley Section): Approx. 114.9mm

Outer Diameter of Rubber Section: Measurement not possible (Reference value approx. 114mm)

Weight: Approx. 3.28kg

Bearing: NSK (Nippon Seiko) 6004DU
*These are approximate values due to simple measurement. Please be aware of tolerance management for precision applications.

■ Features & Value
High rigidity due to the single through-shaft, a structure different from inexpensive split shafts.
Smooth rotation confirmed with NSK bearings.

It has been cleaned with a grinder and wire brush, so it is in maintained condition, but there are some areas where rust cannot be completely removed and polishing scratches remain. Please judge from the images.

This product achieves an astonishing weight reduction of only 3.28kg despite its extra-thick specification with an outer diameter of 114.9mm (approx. 114mm for the rubber part). Normally, iron rollers of this size weigh around 10-15kg, but this achieves both lightness and high rigidity through a through-shaft structure where a 20mm diameter steel core passes through the entire 1070mm length.

It uses reliable NSK (Nippon Seiko) 6004DU bearings, suggesting it may be a custom specification for industrial machinery manufacturers, which is uncommon for general-purpose products.

The slight white spots on the surface are thought to be due to minor oxidation or moisture absorption marks inherent to the material properties and do not affect its use or rotational accuracy.
