Uni / Uni-Drive Poly-Ribs Pulley Profile: J, PK, PL, PM
NU-T-Link & Super T-Link Belts
Modular, Flexible, and Maintenance-Free Power Transmission Belts
Uni-Drive NU-T-Link and Super T-Link belts are high-performance link-type V-belts designed to replace conventional rubber V-belts in both industrial and HVAC applications. Made from precision-engineered polyurethane elastomers reinforced with strong polyester or fabric links, they offer quick installation, high resistance to harsh environments, and reduced downtime.
Product Range
-
NU-T-LINK Belts – equivalent to Classical V-Belt sections (Z, A, B, C, D)
-
SUPER T-LINK Belts – equivalent to Wedge/Narrow sections (SPZ, SPA, SPB, SPC)
-
Available in custom lengths – supplied by the meter or pre-assembled to required drive size
-
Compatible with standard V-pulley grooves
Key Features & Characteristics
-
Fast Installation: Can be fitted without dismantling drive components — ideal for confined or hard-to-reach machines.
-
Adjustable Length: Each link can be added or removed easily to achieve the exact required belt length.
-
High Strength & Stability: Reinforced polyurethane links resist stretching and maintain drive tension.
-
Oil, Water & Chemical Resistant: Performs reliably in damp, oily, or corrosive environments.
-
Reduced Vibration & Noise: Smooth, quiet operation compared to traditional rubber belts.
-
Maintenance-Free: No need for lubrication or re-tensioning after fitting.
-
Resistant to Temperature Extremes: Typically from –20°C to +80°C, depending on belt section.
-
Compatible with Existing Pulleys: Designed to run on standard belt pulleys without modification.
Typical Applications
-
HVAC fans, air-handling units, and cooling towers
-
Pumps, conveyors, mixers, and crushers
-
Machine tools, woodworking and textile machinery
-
Replacement and emergency maintenance drives
