Heavy-Duty 45# Steel Synchronous Pulley, 2-Groove Precision-Machined Assembly

Heavy-Duty 45# Steel Synchronous Pulley, 2-Groove Precision-Machined Assembly

Product Overview

A precision-machined, double-groove synchronous pulley designed for high-torque power transmission. Constructed from 45# steel, it features accurately cut tooth profiles that ensure zero slippage and perfect synchronization with HTD or similar timing belts. The assembly is engineered for applications requiring robust performance, offering excellent resistance to deformation and wear in continuous operation cycles.

This 2-groove synchronous pulley assembly is built to outperform in the toughest industrial environments. It combines robust 45# steel construction with precision CNC machining to deliver:

• Heavy-Duty Performance: Manufactured from 45# steel for superior tensile strength and long-term durability under high loads.

• Precision-Machined Accuracy: Guarantees perfect groove geometry and balance, minimizing belt wear and vibration for smooth, efficient operation.

• Reliable Synchronization: The dual-groove design maintains precise timing and power distribution across multiple belts, eliminating slippage.

FAQ

Q1: What are the primary advantages of using 45# steel for this pulley?
A: 45# steel (equivalent to AISI 1045) offers an excellent balance of high strength, good toughness, and machinability. It is significantly stronger and more wear-resistant than aluminum or cast iron, making it ideal for heavy-duty applications involving high loads, shock forces, and continuous operation.

Q2: Which synchronous belt profiles (pitches) are available for this 2-groove pulley?
A: We can manufacture this assembly to match all common industry-standard pitches, including:

• Metric Pitches: 3M, 5M, 8M, 14M

• T-Series (Trapezoidal) Pitches: T5, T10, T20

• HTD Pitches: 3mm, 5mm, 8mm

• Other Standards: XL, L, H
  Please specify your required pitch when inquiring.

Q3: What is the purpose of a double-groove design?
A: The dual-groove configuration serves two main purposes:

1. Increased Power Transmission: It allows the use of two belts to transmit twice the power of a single-groove pulley within the same space.

2. Enhanced Reliability: It provides redundancy and better load distribution, which is crucial for critical drives where failure is not an option.

Customization & Ordering

Q4: What customization options are available for the bore and mounting?
A: We offer a wide range of mounting solutions to fit your shaft and assembly needs:

• Plain Bore with Setscrews: Standard option for simple mounting.

• Keyway & Setscrews: Most common for secure torque transmission. We offer standard square keyways.

• Taper-Lock Bushings: A popular adapter system for easy installation and removal without heating or pressing.

• Custom Bores: Any diameter and tolerance (e.g., H7, press fit) can be manufactured to your print.

Q5: Can you produce this pulley according to my technical drawing?
A: Absolutely. We specialize in custom manufacturing. Providing your CAD model or detailed technical drawing is the best way to ensure the pulley meets your exact specifications for dimensions, tolerances, and features.

Performance & Durability

Q6: How is the pulley balanced, and why is it important?
A: Our standard pulleys are dynamically balanced to a G6.3 grade, which is sufficient for most industrial applications. Proper balancing minimizes vibration at high speeds, leading to smoother operation, reduced noise, longer bearing life, and increased overall system reliability. Higher precision grades (like G2.5) are available for high-speed applications.

Q7: What surface treatments do you offer to prevent rust?
A: 45# steel is susceptible to corrosion. We offer several surface treatments:

• Black Oxide: Provides a sleek black finish with mild corrosion resistance.

• Zinc Plating: Offers excellent corrosion protection (can be clear, blue, or yellow chromate).

• Powder Coating: Provides a thick, durable, and decorative coating in various colors.

Logistics & Support

Q8: What information do I need to provide to get an accurate quote?
A: To expedite the quoting process, please provide the following:

1. Pitch and Number of Teeth (e.g., 8M, 30 teeth).

2. Bore Specification (e.g., 25mm H7 with a 6x6mm keyway).

3. Quantity Required.

4. Preferred Surface Treatment.
   A technical drawing is the most effective way to convey all requirements.

Q9: What is your typical lead time for a custom order?
A: Lead times vary based on order complexity and quantity. Prototype samples can typically be delivered within 4-6-3 weeks, while production runs may take 6-8 weeks. We always communicate lead times clearly upon order confirmation.
