GBN Machine and Engineering Corp. has developed a new nailing head that incorporates many improvements over the existing machine.

The redesigned frame utilizes linear bearings to guide the driving head, chuck bars and board fence. These roller bearings offer less resistance to motion when compared to the oil-impregnated nylon-against-metal or metal-on-metal guideways that have been used until now.

Linear bearings also remove all unwanted clearance that standard guides require to operate. In addition, they do not require as much lubrication because they are sealed against contaminates entering the bearing or the loss of lubrication from the bearing.

GBN also has gone to tubular steel construction of the frame and most of its components; this allows for easier assembly and added strength and durability.

Other improvements include the driving head cylinder mounting, which now uses a clevis and pin at both ends, making it easier to service and maintain the machine.

All the improvements were aimed at reducing down time and making the machines truly user-friendly. Another benefit is longer stringer length up to 66 inches; stringer length previously had been limited to 60 inches.

All the improvements will become standard on new GBN nailing systems.
