U.s. Tsubaki 6020SB Plain Bore Roller Chain Coupling

Product Description

The U.S. TSUBAKI 6020SB is a plain bore roller chain coupling designed to connect two shafts in power transmission applications. It accepts a 1-inch bore diameter and features a coupling outer diameter of 5.04 inches, making it suitable for moderate-torque drive systems. The coupling uses a standard roller chain design, allowing the chain to flex slightly and accommodate minor shaft misalignment during operation. Licensed technicians and mechanical contractors typically install this component in industrial and commercial machinery settings where shaft coupling is required.

This coupling is used in a range of power transmission setups including conveyor systems, pumping equipment, fans, and general industrial machinery. The plain bore configuration means the installer machines or specifies the keyway and set screw arrangement on-site to suit the specific shaft. It is appropriate for both new installations and replacement of worn or failed couplings in existing drive trains.

Key Features

• Plain bore design allows field-machined keyways and set screws to match shaft specifications
• 1-inch bore diameter for compatibility with standard shaft sizes
• 5.04-inch coupling outer diameter suitable for moderate-torque applications
• Roller chain coupling style provides minor misalignment tolerance between connected shafts
• Compact package dimensions of 6 x 6 x 4.5 inches for straightforward handling and storage

Compatibility

Designed as an OEM-style replacement or new-installation plain bore roller chain coupling for standard power transmission drive systems requiring a 1-inch bore shaft connection.

Installation Notes

Installation should be performed by a qualified mechanical technician. Disconnect and lock out all power sources before removing the existing coupling or fitting the new one. The plain bore must be finish-machined to the required keyway and set screw pattern before mounting on the drive and driven shafts. Verify shaft alignment after installation to minimize coupling wear and bearing load.
