19no Bolt for Connecting Essential disc and Bearing for Agarbatti Making Machine

19 No. TVS Bolt (High Tensile Hex Bolt)

Application:

Used in agarbatti machines to connect the essential disc (rotating disc that feeds or forms the agarbatti sticks) to the bearing set, ensuring proper alignment, rotation, and mechanical stability.

Detailed Description:

The 19 No. TVS Bolt is a high-tensile-grade hexagonal head bolt manufactured by TVS, a reputable Indian fastener company known for producing durable and precision-engineered fasteners. This bolt plays a critical role in the mechanical functioning of agarbatti machines by securely fastening the essential disc to the bearing set, allowing smooth and stable rotation during operation.

Specifications:

• Bolt Size: 19 No. (Corresponds to M12 or M14 depending on machine design; verify specific threading and length)
• Thread Type: Metric fine or standard pitch, fully or partially threaded
• Head Type: Hexagonal
• Material: High-tensile steel, Grade 8.8 or 10.9 (depending on load requirements)
• Coating: Zinc-plated or black oxide finish for corrosion resistance
• Length: Typically between 50mm to 80mm (verify with machine model)
• Tightening Torque: As per standard for grade and size (e.g., ~85 Nm for M12 8.8 grade)

Functional Role:

• Structural Integrity: Ensures rigid coupling between the rotating disc and the bearing unit, critical for continuous, vibration-free operation.
• Rotational Stability: Maintains alignment of the disc with the drive shaft, avoiding eccentric motion which can affect stick formation.
• Load Bearing: Withstands axial and radial forces generated during machine operation.
• Ease of Maintenance: Easily removable using standard spanners for disc or bearing replacement.

Installation Notes:

• Always use a matching TVS nut and washer for uniform torque distribution.
• Apply thread-locking compound if needed to prevent loosening due to machine vibrations.
• Ensure bolt tightness is according to torque specifications to avoid bearing misalignment or disc wobble.

Common Issues if Faulty:

• Loose connection: Causes misalignment, increased wear, or disc wobbling.
• Corrosion or fatigue: Leads to premature bolt failure.
• Wrong size: May strip threads or fail under load, risking machine damage.
