Bearing Wire Rope Pulley

Make wire movement lighter and smoother.

Yokoduna’s Bearing Wire Rope Pulleys are designed for equipment and mechanisms using wire ropes for opening, closing, lifting, and driving. Built-in bearings help reduce resistance and provide smooth wire rope movement.

Two types are available: a Vertical Type and a Vertical/Horizontal Combination Type. 3-sheave and 4-sheave configurations can also be manufactured for systems using multiple wire ropes or complex wire routing.

Applications include stage equipment, tent opening and closing systems, retractable nets in gymnasiums, wire-driven factory equipment, and various opening and closing devices.

Yokoduna has specialized in the design and manufacture of door rollers for many years. While pulleys and door rollers have different applications, they share the fundamental principle of using a rotating wheel to move things.

By applying our technology and expertise in rotating and moving mechanisms, Yokoduna is expanding into new fields where smooth wire rope movement is required.

Yokoduna helps make wire rope mechanisms lighter, smoother, and easier to operate.

Custom-Made Roller Manufacturing Service

“Standard products don’t meet our requirements.” “We need a roller with a specific size or load capacity.” “We need a roller that fits a special rail.” Yokoduna’s Custom-Made Roller Manufacturing Service provides solutions for applications that cannot be covered by standard products.

We can manufacture custom rollers to meet specific sizes, materials, load capacities, and other requirements. Depending on the application, not only the wheel but also the entire frame can be custom-made.

Our engineers work with customers to select the appropriate wheel diameter, width, material, bearing, frame dimensions, and other specifications based on the intended application. We can also consider factors such as the type and shape of the rail, operating conditions, load, and installation space.

From small modifications to completely custom-made rollers, we respond to a wide range of requests. If you are looking for a roller that is not available as a standard product, please feel free to consult with us.

“I need a roller like this.” Yokoduna turns your requirements into a practical roller solution.

Sash Replacement Rollers

“Your sash is difficult to open and close.” “The rollers are making strange noises.” “I want to replace the rollers, but I don’t know which product to choose.” Yokoduna’s Sash Replacement Rollers are designed to solve these common problems.

Sash rollers can wear out over time, causing difficult operation, excessive play, or unusual noises. In many cases, replacing the rollers can restore smooth operation without replacing the entire sash.

Yokoduna’s Sash Replacement Rollers feature a simple insertion-type design for quick, one-touch installation. They are ideal for sash maintenance and roller replacement, helping reduce installation work.

We offer a versatile lineup designed for various types of sashes. If you cannot identify the roller currently in use or are unsure which replacement is suitable, we can help identify a compatible product based on the existing roller, sash shape, dimensions, and other specifications.

As a specialist manufacturer of rollers, Yokoduna provides reliable solutions for smooth sash operation and long-term maintenance.
