Link V Belt
A link V belt is a segmented power transmission belt with interconnected links that can be assembled to the required length. Unlike conventional endless V-belts, it can be installed around existing pulleys without extensive equipment disassembly, making it ideal for restricted-access drives and maintenance applications.
TRANDVOX supplies adjustable link V belts for industrial power transmission and replacement applications, with different profiles and specifications available to match pulley requirements, drive conditions, and operating needs.
Link V Belt Description
A link V belt also referred to as a linked V belt or segmented V belt, is a power transmission belt made from interconnected links. It is also commonly described as an adjustable V belt or adjustable link V belt because its installed length can be changed by adding or removing links.
This segmented construction allows the belt to be assembled around an existing pulley system, which is particularly useful when access to the drive is restricted or removing a motor, shaft, guard, or other components would increase maintenance time. Once assembled, the belt operates in a matching V-belt pulley groove and transmits power through frictional contact between the belt sidewalls and pulley grooves.
For polyurethane-based link V belt constructions, the elastomer provides flexibility and abrasion resistance, while woven polyester reinforcement supports belt strength and dimensional stability during operation. The belt profile and construction should be selected according to the pulley geometry, drive load, operating speed, and working environment.
Link V Belt Types
TRANDVOX supplies two Link V Belt types based on the link construction: without nuts and with nuts. Both types are available in Z10, A13, B17, and C22 profiles.
The link V belt without nuts is available in Z10, A13, B17, and C22 profiles. This type is supplied in red and is selected according to the required belt profile, pulley dimensions, and drive conditions.
The link V belt with nuts is available as Nut Z10, Nut A13, Nut B17, and Nut C22. This type is supplied in orange and features additional nuts in the link construction. Selection depends on the required profile and connection design.

Key Advantages of Adjustable V Belts
Adjustable Length
Links can be added or removed to achieve the required installed length, reducing dependence on fixed-length endless belts. This adjustable V belt design is particularly useful when the required belt length is difficult to determine or when replacement must be completed around an existing drive.
Fast Installation
The belt can be assembled around the existing drive, helping reduce the need for extensive equipment disassembly during replacement.
Ideal for Restricted-Access Drives
Link construction is particularly useful where access to the belt path is limited or moving the motor and other components is inconvenient.
Reduced Maintenance Downtime
Flexible installation and length adjustment can simplify belt replacement and help maintenance teams return equipment to operation more efficiently.
Link V Belt Applications
Link V belts are a type of link drive belt used in industrial power transmission systems where conventional endless V-belts can be difficult to replace or maintain. Their interconnected-link construction allows the belt to be assembled to the required length at the installation location, helping simplify replacement where equipment access, maintenance conditions, or production requirements make conventional belt installation inconvenient.
Fans & Blowers
Fan and blower drives are often located behind guards or inside confined drive assemblies, making access for conventional endless V-belt replacement difficult. A link V belt can be assembled around the existing pulley system, helping reduce the need to remove guards or reposition surrounding components during maintenance.
Pumps
Pump drives can have limited access around the motor, shaft, or coupling, making belt replacement more labor-intensive. A link V belt can be assembled to the required length around the existing drive, helping simplify replacement where removing or moving drive components is inconvenient.
For pump applications, the belt section, load, speed, and operating environment should be matched to the existing pulley system.
HVAC Equipment
HVAC fans and air-handling equipment often place belt drives inside compact equipment housings or enclosed service areas. Limited working space can make installation of a fixed-length endless belt inconvenient during routine maintenance.
A link V belt provides an adjustable replacement option that can be assembled around the existing drive, helping reduce maintenance effort in compact HVAC installations.
Agricultural Machinery
Agricultural machinery is frequently serviced in field conditions where dust, dirt, and limited maintenance facilities can make conventional belt replacement more difficult. A link V belt can be assembled to the required length on site, providing a practical replacement solution when quick field maintenance is important.
Belt construction and profile should be selected according to the machine’s load, speed, contamination, and operating environment.
Woodworking Machinery
Woodworking machinery and dust-collection systems can expose belt drives to sawdust and other airborne debris while placing the drive inside confined machine structures. Replacing a conventional endless belt may require additional access to the drive.
A link V belt can be assembled around the existing pulley arrangement, helping simplify belt replacement on woodworking and dust-collection equipment.
Industrial Machinery
Industrial equipment may incorporate guards, frames, shafts, and other structural components around the belt drive, making conventional belt replacement more time-consuming. A link V belt provides a flexible installation option for suitable drives where access to the belt path is limited.
Its adjustable length can also be useful for maintenance teams handling replacement requirements across different industrial drive configurations.
Glass Tempering Furnaces
Glass tempering production lines depend on continuous operation, and unexpected belt failures in auxiliary drive systems can interrupt production. Fans, blowers, and other belt-driven equipment around the tempering line may also be installed in locations where maintenance access is limited or affected by elevated temperatures.
A link V belt can be assembled to the required length at the maintenance location, helping reduce equipment disassembly and shorten replacement time. For drives exposed to heat-affected areas, the appropriate belt construction and temperature capability should be confirmed based on the actual installation location and operating conditions.
Conveying & Material Handling Equipment
Material-handling systems may use V-belt drives for auxiliary equipment installed behind guards or within machine frames. Limited access can make replacement of a fixed-length endless belt inconvenient and increase service time.
