SURE-GRIP® BUSHINGS Bore and Key Seat Dimensions Sure-Grip Bushings are available from stock with all the bores and keyseats listed below. In some cases, as the bore increases in diameter, a shallow keyseat is provided—due to insufficient metal thickness. When this happens, Wood’s furnishes the correct rectangular key to suit at no charge. This does not affect the bushing’s ability to transmit the load. The rectangular key, or flat key as some call it, fits into the standard keyway in the shaft. DIMENSIONS (In Inches) Product No. (Continued—next page)
