NK25B Standard Bore Sprocket
NK25B Standard Bore Sprocket

What is a Standard Bore Sprocket?
A standard bore sprocket is a type of sprocket that is commonly used in various industrial applications. It is designed to transmit rotational motion between two shafts by means of a roller chain. The standard bore sprocket consists of a circular disc with teeth that mesh with the chain, allowing for smooth and efficient power transmission.
Basic Structure and Customization of Sprockets
When customizing a sprocket, several factors need to be considered:
- Material: The material used for the sprocket depends on the specific application requirements. It can be made of high carbon steel, alloy steel, or stainless steel.
- Tooth Profile: The tooth profile determines how the sprocket engages with the chain. There are various tooth profiles available, each suited for different types of chains.
- Number of Teeth: The number of teeth on the sprocket affects the speed ratio and torque transmission of the system.
- Dimensions: The overall dimensions of the sprocket play a crucial role in determining its compatibility with the application.
- Bore Diameter: The bore diameter refers to the size of the central hole in the sprocket, which fits onto the shaft.
- Keyway: The keyway is a slot on the bore that allows for secure fitting of the sprocket onto the shaft.
- Surface Treatment: The sprocket can undergo various surface treatments, such as rust prevention and hardening, to enhance its durability and performance.
Materials and Manufacturing Process
Our sprockets are manufactured using high-quality materials and advanced manufacturing processes:
- Material: We utilize high carbon steel, alloy steel, or stainless steel, depending on the specific application requirements.
- Manufacturing Process: The sprockets undergo a series of processes, including material selection, cutting, stamping, forging, machining, heat treatment, surface hardening, rust prevention, and quality inspection.
Applications
Our sprockets find applications in various industries, including:
- Heavy Machinery and Equipment
- Food Processing and Packaging
- Chemical and Pharmaceutical
- Assembly Lines
- Logistics and Warehousing

Maintenance and Care
To ensure the longevity and smooth operation of the sprocket, regular maintenance and care are essential:
- Daily Inspection: Check for any signs of damage, misalignment, or wear.
- Cleaning: Remove any dirt, debris, or lubricant buildup from the sprocket.
- Lubrication: Apply a suitable lubricant to reduce friction and wear between the chain and sprocket.
- Adjustment and Calibration: Ensure proper tension and alignment of the chain to prevent premature wear.
Common Problems and Solutions
Some common issues that may arise with sprockets include:
- Skipping Teeth
- Breakage
- Excessive Wear
- Noise
- Chain Slippage
For each problem, there are specific solutions to address them effectively.
