SMW Autoblok is pleased to introduce our newest air chuck design: the BIG BORE® BB-EXL-SC2G. This front-end spring clamp power chuck features an extra long jaw stroke of 1.5 inches, as well as increased safety monitoring to keep up with the changing demands of the oil and gas industries.

For optimal productivity and efficiency, the BB-EXL-SC2G utilizes spring clamping and pneumatic unclamping, cutting costs with lower air consumption.


To expedite the set up process, this air chuck has a step mode for partial opening and clamping when shimming. As a self-centering chuck, it has an open and clamp time of less than three seconds.

SMW Autoblok BIG BORE® BB-EXL-SC2GAvailable with the optional control unit, the stroke control of the BB-EXL-SC2G monitors both the pressure and stroke to ensure that pipes stay in place and won’t allow the jaw to move if the pressure is too low.

To maintain the increased up time, the BB-EXL-SC2G is Proofline® sealed for low maintenance. The permanent grease lubrication helps the chuck retain constant grip force for more efficient turning.
