The Bobbin Race Cover (part # 352075), also known as a Race Gate or Shuttle Race Cover, is a specialized plastic gate that holds the shuttle and bobbin case securely within the race assembly of Singer zigzag sewing machines. This critical component prevents the shuttle from falling out during high-speed zigzag operations and ensures the bobbin area remains properly aligned for consistent stitch formation.

Specifications:

• Part Number: 352075
• Alternate Part Number: 352074
• Type: Replacement (aftermarket)
• Material: Plastic construction
• Made in USA
• Function: Secures shuttle and bobbin case in race assembly

Machine Compatibility:

Fits Singer models: 237 Fashion Mate (all variations), 239, 293, 293B

Function & Benefits:

This race cover is essential for proper bobbin area operation on zigzag machines. It prevents the shuttle from dislodging during the side-to-side needle motion of zigzag stitching, maintains proper alignment of the bobbin case within the race assembly, and ensures consistent stitch quality during both straight and zigzag sewing. Without a properly functioning race cover, the shuttle can shift or fall out, causing jamming and stitch problems.

Common Issue:

The original plastic race covers on these models are prone to cracking over time due to age and stress from repeated use. A cracked or broken race cover cannot properly retain the shuttle, leading to bobbin area problems. This replacement cover restores proper function and prevents shuttle movement.

Installation Note:

Replace a damaged, cracked, bent, or missing race cover to restore proper shuttle retention and bobbin area function. Ensure the cover is properly seated and secured to prevent shuttle movement during operation.
