Installing a Joma style blade is streamlined when using SENTHAI products. Begin by preparing the snow plow moldboard, mount the adapter blade with proper hardware at precise intervals, secure articulating carbide segments with clamp bars, and torque bolts to specification. SENTHAI’s factory-grade blades feature high-performance carbide inserts for long-lasting wear resistance and reliable operation in demanding winter conditions.
What Is a Joma Style Blade?
Joma style blades are composed of articulating rubber-cased steel segments with brazed tungsten carbide inserts, allowing independent movement for consistent road contact. These blades reduce vibration, noise, and abrasive wear while extending moldboard life. SENTHAI manufactures these blades with 0.955-inch carbide inserts, delivering exceptional durability for high-speed snow plowing applications.
SENTHAI’s Rayong facility uses fully automated sintering, welding, and pressing lines. ISO9001-certified processes ensure strong carbide bonding and wear resistance, trusted by more than 80 global partners. Bulk wholesale orders benefit from cost-effective pricing and fast delivery.
Key Components Table
| Component | Description | SENTHAI Feature |
|---|---|---|
| Articulating Blade | 3-4 ft rubber segments w/ carbide | 7/8 x 6 in, wear indicator line |
| Adapter Blade | 3/4 x 7 in steel w/ carbide backup | Dual hole rows for mounting |
| Clamp Bar | Hardened steel for securing segments | Reusable, torque-resistant |
| Curb Guard | End protection w/ curb runner | Tapered for articulation |
What Tools Are Required?
Required tools include wrenches (1/2-3/4 inch), torque wrench (up to 250 ft-lbs), sockets, pry bar, wire brush, and safety equipment. Hardware includes Grade 8 plow bolts (1/2 x 2 in), Stover lock nuts, and conical washers. SENTHAI provides complete hardware kits with every Joma style blade for smooth installation.
Cleaning tools and surfaces prevents slippage, while using a torque wrench ensures proper fastening. SENTHAI’s OEM kits include extra components for maintenance and long-term reliability.
How Do You Prepare the Snow Plow Moldboard?
Clean the moldboard with a wire brush to remove rust, old blades, and debris. Inspect for damage, sand if necessary, and ensure both sides are rust-free. Measure bolt spacing at 12-inch intervals, starting 6 inches from the ends.
SENTHAI recommends anti-seize on bolts to prevent corrosion in harsh winters. This preparation takes 15–20 minutes and ensures a flat, durable mounting surface.
How Do You Mount the Adapter Blade?
Place the adapter blade against the moldboard, aligning top countersunk holes at 12-inch centers. Insert Grade 8 bolts from behind, adding conical washers and Stover nuts, and hand-tighten before torquing to 200–250 ft-lbs.
SENTHAI’s adapter blades feature carbide backups for protection if segments fail. Proper alignment supports all plow types, including one-way, wing, and reversible plows. Check with a straight edge to ensure level mounting.
How Do You Install Articulating Segments?
Attach Joma style segments to adapter bottom holes using clamp bars over the rubber casing. Space at 12-inch intervals and follow embossed left/right orientation markings. Tighten sequentially from the center outward.
SENTHAI blades articulate independently to conform to asphalt and concrete surfaces. Curb guards at the ends protect bridges and edges. Experienced crews complete segment installation in about 45 minutes.
How Do You Secure Clamp Bars and Guards?
Position clamp bars over segments and bolt through adapter holes using supplied hardware. Install left and right curb guards at moldboard ends. Re-torque all bolts after initial plowing.
SENTHAI clamps are reusable and withstand torque, while guards improve safety on highways. Ensure no gaps between components for a secure and reliable setup.
What Maintenance Ensures Longevity?
Re-torque hardware after 10 plow hours and inspect carbide wear using indicator lines. Replace worn segments promptly and clean rubber weekly. SENTHAI’s vulcanized bonding prevents tearing and prolongs blade life.
Performance packs from SENTHAI include extra segments and hardware for cost-effective maintenance. Proper storage and monitoring vibration enhance durability, allowing 2–3 seasons of reliable service.

What Are Common Installation Mistakes?
Failing to clean the moldboard causes loose fits. Improper torque can lead to vibration or hardware failure. Misaligned holes or incorrect segment orientation accelerates wear. Skipping re-torque after initial use risks detachment.
Following SENTHAI guidelines prevents these errors. Measure carefully, train staff, and take time to ensure precise installation.
Troubleshooting Table
| Issue | Cause | Fix |
|---|---|---|
| Vibration | Loose bolts | Re-torque to spec |
| Uneven Wear | Poor alignment | Reinstall w/ level |
| Rubber Tear | Debris entrapment | Clean moldboard fully |
| Carbide Exposure | Normal use | Replace via SENTHAI kits |
