Power Drive AL50 Chain Coupling Cover 4.750 In

SKU CH-W1K1-ZYNKB

Transparent cast-aluminium chain coupling cover fits 4.750 in outside diameter and 2.0000 in width, tolerating 0.005 in parallel and 7° angular misalignment

  • Product colorTransparent
  • Protects chain coupling with durable cast aluminium construction
  • Fits 4.750 In outside diameter for precise alignment
  • Handles -25 to 150 °F operating temperature range
  • Allows 0.005 In parallel and 7° angular misalignment
  • Transparent cover enables quick visual inspection of coupling

Chain Coupling Cover 4.750 In

This transparent cast-aluminium cover fits over a chain coupling with an outside diameter of 4.750 In and a width of 2.0000 In. It is designed for maintenance teams who need to protect the coupling in industrial power-transmission setups. The cover operates reliably from -25 to 150 Degrees F.

Misalignment Tolerances

The cover accommodates parallel misalignment up to .005 In and end float up to .060 In. Angular tolerance is 7 Degree for couplings with 10 to 19 teeth and 1/2 Degree for those with 20 to 24 teeth. Buyers whose shafts exceed these limits cannot use this cover.

Installation Notes

The cover slides onto the coupling and is secured with the hardware supplied for use with 6AGR9 and 6AGR0 couplings. Misalignment beyond the stated tolerances is the most common cause of premature wear or noise. Verify shaft alignment before final tightening.

Questions about this item

What does the 4.750 In outside diameter mean when the cover is installed on a chain coupling?

The 4.750 In outside diameter is the overall width of the cast aluminum cover, so the installed assembly needs at least that much radial clearance around the coupling.

How do the angular misalignment tolerances of 7 degrees for 10T-19T and 1/2 degree for 20T-24T limit the shafts I can connect?

Couplings with 10 to 19 teeth can tolerate up to 7 degrees of angular offset, while 20 to 24 tooth couplings are limited to 1/2 degree, so shaft alignment must stay within the range for your tooth count.

What physical space and mounting provisions does the 2.0000 In wide cover require?

The cover is 2.0000 In wide, made of cast aluminum, and fits couplings such as 6AGR9 and 6AGR0; allow the stated end float of 0.060 In and parallel misalignment of 0.005 In when positioning shafts.
