1/4" x 1-1/2" Machine Key for CPLG5016 Chain (Grade 1018 Steel)
The Fastenal 1/4" x 1/4" x 1-1/2" Machine Key (0953162) is a high-precision, undersized square key designed to link rotating shafts to gearboxes, sprockets, and pulleys. Within Tommy Car Wash Systems, this crucial piece of hardware is specifically deployed inside the Drying Rack Coupler & Chain assembly and various Conveyor Belt mechanical drive lines.
When an electric motor spins, a machine key ensures that torque transfers cleanly to the drive gears without the shaft slipping inside the housing. This specific model features an undersized tolerance profile, allowing a slightly easier, slip-fit slide into worn or tightly packed keyways during field maintenance—saving you time when completing critical on-site repairs.
Key features and benefits include:
- Targeted System Fitment: Factory-dimensioned to fit the exact keyways found inside Tommy conveyor drive rollers and drying rack chain coupler shafts.
- Undersized Tolerance Profile: Specifically manufactured slightly below nominal 1/4" dimensions to slip smoothly into standard keyways without requiring heavy filing or forcing.
- Dependable Carbon Steel Build: Forged from Grade 1018 low-carbon steel to handle continuous high-torque starting and stopping cycles along the main conveyor belt.
- Preventative Backup Essential: Because keys act as intentional mechanical shear points to protect expensive gearboxes during severe system jams, keeping a few of these in your backroom prevents long-term tunnel closures.
