Features
◇ Oilless, wear-resistant bushing is built in the guide sleeve
◇ With double buffer springs
◇ Non-rotating type can be selected
◇ Various buffer stroke specifications are available
Advantages
◇ Reduce product wear, improve the lifetime of the products
and reduce the noise
◇ Flexible contact with fragile workpieces, compensate the height
difference of workpieces
◇ Suitable for precise positioning of oval suction cup
◇ Suitable for various working conditions
Applications
◇ Suitable for handling heavy workpieces, such as steel plate
◇ Suitable for the working conditions that need flexible contact
and shock absorption when carrying objects, such as glass
◇ Suitable for use in harsh environment
◇ Non-rotating level compensator is suitable for oval suction cup
◇ Double spring buffer structure can prevent the impact on the
support rod end when handling the workpiece and turning it over

Structure
◇ (1) Vacuum generator connection
◇ (2) Spring
◇ (3) Mounting nut
◇ (4) Guide sleeve
◇ (5) Spring
◇ (6) Suction cup connection

◇ Note: 1. Pretightening force is spring elastic force when spring is compressed in nature state
2. Elastic force is spring elastic force when level compensator is compressed in 50% stroke, it is suggested that the actual working compressed
stroke of level compensator does not exceed 50% of its max. compressed stroke
3. Vertical load refers to the max. vertical tension that the level compensator can bear in static state
4. When the level compensator is installed horizontally, the workpiece will produce gravity perpendicular to the direction of the level compenasator,
If the gravity is bigger than the horizontal load range, the spring may get stuck
