Principle of SS12AH-2/SS60H-2 Heavy Duty Series Stainless Steel Roller Chains
The SS12AH-2/SS60H-2 Heavy Duty Series Stainless Steel Roller Chains are designed to transmit power and bear heavy loads in mechanical transmissions. These chains are composed of interconnected roller links and pin links that rotate around a sprocket to transmit power.
The working principle of the Heavy Duty Series Stainless Steel Roller Chains is based on the fact that the rollers can reduce friction between the chain and the sprocket. As the chain moves around the sprocket, the rollers allow the chain to smoothly glide over the sprocket teeth, minimizing wear and tear on both the chain and the sprocket.
One of the key performance features of these chains is their ability to handle heavy loads. The rollers are designed to distribute the load evenly across the pins, thus preventing any one link from bearing the full load. Additionally, the pins are made of high-strength stainless steel, which allows the chain to withstand heavy loads without breaking or deforming.
The SS12AH-2/SS60H-2 Heavy Duty Series Stainless Steel Roller Chains are also designed to transmit power efficiently. The rollers reduce friction between the chain and the sprocket, allowing the chain to transfer power with minimal energy loss.

Maintenance and Care of SS12AH-2/SS60H-2 Heavy Duty Series Stainless Steel Roller Chains
- Regular lubrication: It is essential to lubricate the heavy-duty stainless steel roller chains at frequent intervals to reduce friction and prevent wear. Use a high-quality lubricant specifically designed for roller chains.
- Inspect for damage: Regularly inspect the chains for any signs of wear, corrosion, or damage. Replace any worn-out or damaged links promptly to ensure optimal performance.
- Cleaning: Clean the chains with a mild solvent or detergent to remove any dirt, debris, or contaminants. Use a soft brush to scrub gently, and rinse with clean water. Dry thoroughly before re-lubricating.
- Tension adjustment: Check the chain tension periodically and adjust it if necessary. Improper tension can lead to premature wear or breakage. Consult the manufacturer's guidelines for proper tensioning procedures.

Why Choose Our Stainless Steel Roller Chains?
Our SS12AH-2/SS60H-2 Heavy Duty Series Stainless Steel Roller Chains offer several key advantages:
- High Strength: Our stainless steel chains have a strength that is typically 60%-70% of carbon steel, surpassing the general strength of regular stainless steel.
- Material Options: We offer chains made from the 300, 400, and 600 series, providing a range of options to suit different applications.
- Tight Clearances: Our chains have small gaps and high precision, ensuring a tight fit.
- Superior Chain Plate Quality: Our chain plates undergo a heat treatment process that involves controlled deformation or stress relief during the cooling process, guaranteeing precise dimensions and mechanical performance.
- High-Pressure Surface Treatment: The chain plates undergo high-pressure processing to enhance the durability of the material.
- Uniform Plate Thickness: The chain plates are evenly thick, and the bright bands formed by double punching ensure a tight connection with small pipes and pins.
- Centralized Hole Positioning: All holes are perfectly centered on the chain plates, without any deviation.
- High Flatness of Chain Plates: The chain plates have excellent flatness.

How To Select Sprockets For Stainless Steel Chains?
When selecting sprockets for SS12AH-2/SS60H-2 Heavy Duty Series Stainless Steel Roller Chains, it is important to consider the pitch, number of teeth, bore size, and hub style. The pitch refers to the distance between the centers of two adjacent chain pins and must match the pitch of the chain. The number of teeth on the sprocket should be compatible with the number of chain links. The bore size should fit the shaft diameter to ensure proper alignment. The hub style can be either a Type A hub, which is suitable for most applications, or a Type B hub, which is used for higher torque loads.
Our company offers a wide variety of sprockets for stainless steel chains, including taper bushed sprockets, QD (quick detachable) sprockets, and finished bore sprockets. These sprockets are made from high-quality stainless steel to ensure durability, corrosion resistance, and long service life.
Please see the attached image for an example of stainless steel sprockets that we offer.
