#50 Roller Chain – 10-Foot Replacement Drive Chain, 5/8" Pitch

This #50 roller chain provides a 10-foot length for replacing drive chain on compatible garage door operators, gate operators, and other equipment specifying #50 roller chain. It transfers motion between matching sprockets and can be shortened to the required length using a suitable chain breaker.

Match the chain size, construction, and equipment requirements before ordering.

PRODUCT DETAILS

• Chain size: #50
• Supplied length: 10 feet / 120 inches
• Standard chain pitch: 5/8" (0.625")
• Standard inside width: 3/8" (0.375")
• Standard roller diameter: 0.400"
• Type: Roller drive chain

Pitch is measured between the centers of adjacent chain pins. Inside width is the space between the inner link plates, not the chain’s overall outside width.

COMPATIBILITY

For equipment designed to use #50 roller chain with matching sprockets and an approved connecting link.

Before ordering, confirm:

• Chain size specified in the equipment manual
• Pitch, inside width, and roller dimensions
• Required chain length and strand configuration
• Manufacturer’s load and operating requirements
• Condition and alignment of the existing sprockets

#50 chain is not interchangeable with #40 or #41 chain, which use a smaller 1/2" pitch. Select by chain specification rather than operator brand alone.

This is roller drive chain, not the loop-style hand chain used to manually operate a door hoist.

LENGTH AND CONNECTING LINKS

The supplied 10-foot length may require shortening for your application. Measure the required chain path and follow the equipment manufacturer’s sizing instructions.

Use a compatible #50 master link when the installation requires a removable connection. Master-link inclusion is not specified in this listing.

INSTALLATION NOTES

Disconnect equipment power, secure the door or gate, and relieve chain tension according to the manufacturer’s instructions before replacement.

Inspect sprockets for worn or damaged teeth. Set chain alignment, tension, and lubrication to the equipment specifications. Confirm free movement and reinstall all guards before operating.

SAFETY

Keep hands, clothing, and tools clear of chain and sprocket pinch points. Never adjust or lubricate a moving chain.

Do not use this drive chain as a lifting sling or load-suspension chain. Have a qualified technician inspect equipment with binding, damaged sprockets, or recurring chain failures.
