Low-profile lock nut rams (sometimes called pancake cylinders) have a low height when fully retracted, allowing them to be used in tight or confined spaces. They have a shorter stroke length than standard lock nut rams. Lock nut rams have an integrated locking ring that helps secure heavy loads for short periods of time.

General purpose lock nut hydraulic rams are used for most common lifting and support applications. They have a locking ring around the piston that can be tightened to maintain the correct height and help support the workpiece for short periods of time.

Lightweight lock nut rams are made out of aluminum to reduce weight compared to standard steel cylinders, making them more portable and easier to move. Lock nut hydraulic rams have a locking ring to help secure heavy loads for short periods of time.
