219H vs 219SH Go Kart Chain – What’s the Difference?
What Is a 219 Go Kart Chain? Complete Guide to 219H and 219SH Chains
A go kart chain transfers power from the engine to the rear axle. Choosing the right chain ensures reliable performance, smooth operation, and longer drivetrain life.
Among karting chains, the 219 size is a compact option for specific power transmission systems. Two common versions are 219H and 219SH.
Both share the same 7.774 mm pitch and 4.59 mm roller diameter. But they differ in inner width, plate thickness, pin dimensions, and tensile strength. These differences matter for replacement, OEM, and wholesale sourcing.
This guide covers key specifications, compares both chains, and offers practical advice on selection, sprocket matching, maintenance, and B2B purchasing.
What Is a Go Kart Chain?
A go kart chain is a mechanical transmission chain that transfers rotational force between two sprockets.
Typical drivetrain flow:
Engine → Drive Sprocket → Chain → Rear Sprocket → Axle
The chain engages sprocket teeth and transmits engine rotation to the axle. Selection must be based on technical specifications, not appearance.
Key specifications include:
- Chain designation
- Pitch
- Inner width
- Roller diameter
- Plate thickness and height
- Pin diameter and length
- Tensile strength
- Chain length
- Sprocket compatibility
Always confirm these specifications before ordering.
What Does 219 Mean on a Go Kart Chain?
The 219 designation identifies a specific chain size for karting and compact drives.
The 219 chain covered here has a 7.774 mm pitch. Pitch is the center-to-center distance between adjacent pins. It must match the sprocket geometry.
The number "219" does not indicate length or strength. It defines the chain size and helps determine the correct sprocket.
When ordering, confirm whether you need 219H or 219SH because their dimensions and strength specifications are different.
219H vs 219SH Go Kart Chain
Both versions share:
- 7.774 mm pitch
- 4.59 mm roller diameter
- 7.5 mm inner plate height
But they differ in:
- Inner width
- Outer and inner plate thickness
- Pin diameter and length
- Minimum and average tensile strength

219H vs 219SH: Complete Comparison
| Specification | 219H | 219SH |
|---|---|---|
| Pitch | 7.774 mm | 7.774 mm |
| Inner Width | 5.00 mm | 4.60 mm |
| Roller Diameter | 4.59 mm | 4.59 mm |
| Outer Plate Thickness | 1.0 mm | 1.3 mm |

| Average Tensile Strength | 850 kgf | 1,200 kgf |
The two chains have the same pitch and roller diameter, but different inner width, plate thickness, pin dimensions, and strength.
Higher tensile strength does not automatically make one chain better for every application. Dimensional fit and operating conditions also matter.
Main Differences Between 219H and 219SH
Inner Width
219H = 5.00 mm; 219SH = 4.60 mm. This difference affects the relationship between the chain and sprocket.
Plate Thickness
| Plate | 219H | 219SH |
|---|---|---|
| Outer | 1.0 mm | 1.3 mm |
| Inner | 1.2 mm | 1.4 mm |
Pin Dimensions
| Pin | 219H | 219SH |
|---|---|---|
| Diameter | 3.01 mm | 3.02 mm |
| Length | 11.7 mm | 12.0 mm |
Tensile Strength
| Strength | 219H | 219SH |
|---|---|---|
| Minimum | 750 kgf | 1,000 kgf |
| Average | 850 kgf | 1,200 kgf |
Always consider working conditions, sprocket alignment, lubrication, speed, and load, not just tensile strength.
How to Choose the Right 219 Chain
1. Confirm Chain Type
Check the chain marking, technical drawing, purchase record, or existing sample. If unsure, send a sample to the manufacturer for verification.
2. Check Dimensions
Verify pitch, inner width, roller diameter, plate thickness and height, pin diameter, and pin length. Pitch alone is not enough.
3. Inspect the Sprocket
Ensure sprocket size, tooth condition, width, engagement, and alignment are compatible. A worn sprocket can shorten the service life of a new chain.
4. Confirm Length
Provide the number of links, existing chain length, sample, or desired finished length. For OEM and wholesale orders, confirm the required length before production.
5. Consider Operating Conditions
Engine output, speed, load, shock loading, operating frequency, lubrication, dust, and alignment can all affect chain wear and service life.
Sprocket Compatibility
Chain and sprocket must work as a matched set.
Mismatching can cause poor engagement, excessive noise, rapid wear, vibration, derailment, or premature failure.
Always inspect sprockets when replacing a chain. If the teeth are badly worn, replacing both the chain and sprocket may be necessary.
For OEM builders, sourcing chain and sprockets from one supplier can simplify specification control.
Installation and Maintenance
Alignment
Keep the drive and rear sprockets properly aligned. Misalignment can create lateral forces and uneven wear.
Tension
Do not over-tighten the chain. Excessive tension stresses chain and drivetrain components, while too much slack can increase the risk of derailment. Follow the equipment guidelines for proper adjustment.
Lubrication
Regular and suitable lubrication reduces friction between moving chain components. The lubrication method should be selected according to the operating environment.
Sprocket Inspection
Check for abnormal tooth wear, damage, uneven wear, and poor chain engagement. Replace the sprocket if its condition affects chain performance.
Chain Inspection
Look for elongation, stiff links, damaged rollers, plates or pins, excessive side play, corrosion, or unusual operating noise. Early detection can help prevent transmission problems.
When to Replace a 219 Chain?
There is no fixed replacement interval for every 219 chain. Service life depends on load, power, speed, lubrication, alignment, sprocket condition, operating frequency, and environment.
Inspect the chain regularly. If you see significant wear, elongation, damaged components, or poor sprocket engagement, replace the chain and check the sprockets at the same time.
For B2B Buyers
Distributors, wholesalers, OEM manufacturers, and maintenance companies should consider more than unit price when sourcing a 219 go kart chain.
- Consistent dimensions – Ensure pitch, width, roller, plate, and pin specifications remain consistent across production batches.
- Stable quality – Repeat customers need the same specification for future orders.
- Custom lengths – Different applications require different link counts. Confirm the required length before ordering.
- OEM solutions – Requirements may include custom lengths, packaging, private labeling, technical drawings, matching sprockets, or special production.
- Bulk orders – Specify quantities and packaging requirements in your RFQ for accurate pricing.
How to Order 219H or 219SH
Provide as much detail as possible in your RFQ:
- Chain designation
- Required quantity
- Number of links / required length
- Application
- Sprocket information
- Technical drawing or sample
- Packaging requirements
- OEM requirements
If you are uncertain which version you need, send a sample or drawing. The manufacturer can verify the dimensions before production.
