Important technical information Types of operation Spring force Hydraulic and spring force Stroke Off-position: Support plunger retracted The support plunger contacts the workpiece by air pressure. The contact force is proportional to the air pressure less spring force. The support plunger will be locked by hydraulic pressure and can compensate forces in axial direction. For retraction, hydraulic and air pressure will be released. The support plunger retracts by spring force relatively slowly to its off-position. Off-position: Support plunger retracted The support plunger is extended by a...

Important technical information Contact force The workpiece must not be deformed by the contact of the support plunger. Therefore, the contact is made with spring force or pneumatically. Depending on the size, the spring forces are between 4 and 100 N. With hydraulically extendable work supports, the contact force is the smallest, when the distance between the contact bolt and the workpiece is the largest before getting in contact. Max. distance to the workpiece reduces the contact force Metallic wiper edge and wiper The metallic wiper protects the wiper underneath against hot swarf or high...

Important technical information Contact bolts Most of the work supports are delivered with a contact bolt in the support plunger. This contact bolt has a dome-head and hardened contact surface. Attention ! Never use the work support without contact bolt, since penetrating dirt and liquids impede the function. Protection cap The protection cap is designed to protect the wiper, if a strong coolant jet is directed at the support plunger or the metallic wiper edge. For some threaded-body work supports, protection caps are available as an accessory. Contact bolt Seal Dimension tolerances If not...
