PAGOW #40 Roller Chain Connecting Links – 5pcs Heavy Manganese Steel

Description

Product Overview

PAGOW #40 roller chain connecting links are engineered to meet the rigorous demands of high‑performance power transmission systems used in miniature motorcycles, go‑karts, and a variety of small‑engine equipment. Each link is fabricated from premium manganese steel, a material known for its exceptional tensile strength, wear resistance, and ability to maintain structural integrity under fluctuating temperature conditions. The pack includes five precisely machined master connector links, each measuring 0.4 × 0.89 × 0.69 in (10.2 × 22.7 × 17.5 mm), providing a seamless fit for standard #40 roller chains. The design incorporates a reinforced pin and bushing system that distributes load evenly, reducing the risk of chain elongation and ensuring consistent power delivery across the entire drivetrain.

These links are finished with a corrosion‑resistant coating that protects against rust and environmental degradation, extending service life even in harsh outdoor settings. The heavy‑duty construction is complemented by a compact profile that minimizes added weight while delivering maximum strength. The product dimensions of the packaging are 7.64 × 4.61 × 0.63 in, weighing only 1.45 oz, making storage and handling straightforward for both professional mechanics and hobbyist enthusiasts.

Usage

These master links are ideal for a range of applications where reliability and durability are paramount. They are commonly used in Baja Doodle Bug Motovox Mini Bikes, Harbor Freight Predator 212cc Go‑Kart carts, and other custom‑built racing machines that require a secure chain connection. The links excel in environments that experience rapid temperature changes, such as competitive racing events where chains are subjected to intense heating during operation and sudden cooling during breaks. Their ability to resist heat‑induced cracking makes them a preferred choice for users who demand consistent performance without the need for frequent replacements.

Installation is straightforward: simply align the master link with the existing chain ends, insert the pins, and secure them using the provided tool or a standard chain pin press. The design ensures a tight fit that eliminates any play, which is critical for maintaining precise timing and power transfer. Users can confidently employ these links in both new builds and retrofit projects, knowing that the product meets industry standards for safety and performance.

FAQ

What chain sizes are compatible with these master links?

The #40 master links are compatible with standard #40 roller chains, which are commonly used in mini‑bikes, go‑karts, and small‑engine equipment. They fit chains with a pitch of 0.5 in and a roller width of 0.25 in.

Can these links be used in high‑temperature racing environments?

Yes. The manganese steel construction and heat‑resistant design allow the links to withstand the intense heating that occurs during competitive racing, reducing the likelihood of heat‑induced cracking.

How do I install the master links correctly?

Align the master link with the ends of the existing chain, insert the pins, and press them firmly using a chain pin press or a compatible tool. Ensure the pins are fully seated to achieve a secure, gap‑free connection.

Do the links require any special maintenance?

Regular lubrication of the chain and periodic inspection for wear are recommended. The corrosion‑resistant coating minimizes maintenance, but cleaning the links after exposure to mud or salt will help preserve their appearance and performance.
