HUAYE-190 Bolt Solid Plate Conveyor Belt Fastener for Mechanical Belt Splicing
The HUAYE-190 is a bolt solid plate belt fastener designed for fast, reliable mechanical splicing of EP and NN fabric-core conveyor belts. Rated at 65 kN/m (375 PIW), it handles medium-to-heavy-duty belt tensions — and with 25 fastener sets per box, your maintenance team has everything needed to complete a belt splice or rip repair on site, without vulcanizing equipment.
- Belt Thickness: 8–14 mm (5/16″–9/16″)
- Rated Tension: 65 kN/m (375 PIW)
- Min. Pulley Diameter: 460 mm (18″)
- No Vulcanizing Equipment Required
Why Choose a Bolt Solid Plate Fastener for Mechanical Belt Splicing
When a conveyor belt fails mid-shift, the priority is getting it back in operation fast — without waiting for vulcanizing equipment or a specialist crew. The HUAYE-190 bolt solid plate fastener is designed for exactly this: a field-installable mechanical belt splice that holds up under medium-to-heavy tension and keeps your conveyor running until a permanent repair can be scheduled.
Unlike hot vulcanization, mechanical belt fastening with bolt solid plate fasteners requires no heat, no chemicals, and no specialist training. Any maintenance team can complete a super screw belt splice with standard tools — punch, wrench, and bolt breaker — reducing unplanned downtime from hours to minutes.
Where HUAYE-190 Belt Fasteners Are Used
The HUAYE-190 is suited to medium-to-heavy-duty conveyor belt splicing and emergency rip repair across mining, port, quarrying, and industrial plant operations — anywhere EP, NN, or CC fabric-core belts are running and downtime is not an option.
Its bolt solid plate design distributes splice tension evenly across the full fastener width, reducing stress concentration at the splice point — a common failure mode with lower-grade belt fasteners.

Conveyor Belt Fastener Selection Guide
Match your belt thickness and tension rating to the correct HUAYE fastener size. If your belt sits at the boundary between two sizes, always select the larger size for a safer splice.
| Model | Belt Thickness (mm) | Belt Thickness (inch) | Max Tension (kN/m) | Max Tension (PIW) | Min. Pulley Dia. (mm) |
|---|---|---|---|---|---|
| 140 | 5–11 | 3/16″–7/16″ | 40 | 225 | 360 |
| 190 ← You are here | 8–14 | 5/16″–9/16″ | 65 | 375 | 460 |
| 1.5″ | 11–17 | 7/16″–11/16″ | 50 | 300 | 460 |
| 2″ | 14–21 | 9/16″–13/16″ | 75 | 440 | 760 |

How to Install HUAYE-190 Belt Fasteners
- Prepare the Belt End: Cut the belt end square and clean. Mark the fastener spacing across the belt width.
- Punch the Holes: Use a belt punch tool to create clean holes at marked positions through the belt thickness — avoid tearing the belt carcass.
- Insert the Bolts: Insert the piloted bolts through the bottom plate from below, then push up through the punched belt holes.
- Fit the Top Plate: Position the top plate over the protruding bolt tips and press down firmly so the teeth seat fully into the belt surface.
- Tighten the Bolts: Use a power wrench or hand wrench to tighten each bolt to the correct torque — work from the center outward to ensure even plate compression across the belt width.
- Break Off Excess Bolt: Use a bolt breaker to snap off the excess bolt shank flush with the nut. The belt fastener is now installed and the splice is ready for operation.

Installation Notes
Always verify your belt thickness falls within the 8–14 mm range before ordering HUAYE-190 fasteners. Using a fastener outside its rated thickness range will reduce splice strength and service life.
Do not exceed the rated tension of 65 kN/m (375 PIW). For higher-tension applications, select the 2″ model.
Ensure bolt torque is applied evenly across all fasteners in the splice — uneven tightening creates stress concentration and accelerates fastener wear.
Inspect the splice periodically during operation. Replace individual fasteners showing signs of deformation or tooth pull-out before the full splice fails.
Frequently Asked Questions
What belt types is the HUAYE-190 conveyor belt fastener compatible with?
HUAYE-190 is compatible with EP (polyester-nylon), NN (nylon-nylon), and CC (cotton-core) fabric-core conveyor belts within the 8–14 mm thickness range. It is not suitable for steel cord belts.
Can HUAYE-190 fasteners be used for emergency rip repair?
Yes. Bolt solid plate fasteners like the HUAYE-190 are commonly used for emergency rip repair and super screw belt splice applications — they can be installed on-site by maintenance staff without vulcanizing equipment, getting the belt back in operation quickly.
What tools are needed to install HUAYE-190 belt fasteners?
Installation requires a belt punch tool, power wrench or hand wrench, and a bolt breaker to snap off excess bolt shank. No specialist equipment or hot vulcanizing press is required.
How do I know if HUAYE-190 is the right size for my belt?
Check your belt thickness. HUAYE-190 covers 8–14 mm (5/16″–9/16″). For thinner belts (5–11 mm), select the 140 model. For thicker belts (11–17 mm or 14–21 mm), select the 1.5″ or 2″ model respectively. Refer to the selection guide table above.
What is the maximum belt tension HUAYE-190 can handle?
HUAYE-190 is rated at 65 kN/m (375 PIW). For higher-tension applications exceeding this rating, select the 2″ model rated at 75 kN/m (440 PIW).
How many fastener sets come in one box?
Each box contains 25 fastener sets. Net weight per box is 2.16 kg (4.76 lbs).
