The patented SGS™ TGVS Series non-drive end shaft grounding system was developed specifically for applications with narrow outside axial clearance. Have a motor where the non-drive end is butted up against an obstruction? The TGVS will likely fit between the motor and obstruction. The TGVS requires only 1.0 inch outside axial clearance while still allowing access to the brush for infrequent brush maintenance. Maintenance can be done while the motor is in operation a unique feature of SGS™ non-drive end shaft grounding systems.
The axial distance between the end of the non-drive end shaft and the outside of the fan cover/end bell must be determined to within 1/8 to 1/16" accuracy.
A 1.0 inch diameter hole is needed in the fan cover/end bell to gain access to the non-drive end shaft. The end of the non-drive end shaft must not have a hole to allow for a 1/4 x 20 attachment bolt. If a hole already exists, then the bolt hole diameter, depth and TPI must be determined for custom adaptation.
