Series MGF Specific Product Precautions Be sure to read before handling. Refer to front matters 2 and for Safety Instructions and pages to 11 for Actuator and Auto Switch Precautions. Caution Selection Operate loads within the range of the operating limits. Select a model taking into consideration the allowable horizontal loads, rotational torque and eccentric loads that will apply. When used in excess of the applicable limit, eccentric loads applied to the tube guide will cause wear of the guide, increase the guide s deviation range, cause stress cracks and breaks on the mounting bolts, and decrease the life of the cylinder. Do not allow any dents, scratches, or other damage on the mounting faces of either the plate or end plate. The flatness of the mounting face may deteriorate, the guide's deviation range may increase and the sliding resistance may become greater. Do not allow hands or fingers near the cylinder during its operation. Your fingers may be caught between the body and the plate. If you need to come near the cylinder during its operation, install a cover on the cylinder. Caution Mounting from upper side Model MGF MGF MGF Bolt M6 x 1 M8 x 1.2 M x 1. Mounting For mounting the cylinder, use screws that meet the appropriate length and tighten within the limits of the maximum tightening torque. Maximum tightening torque (N m) 2 1 l l 7. Mounting from bottom side l Do not bring objects that are sensitive to magnetism near the cylinder. There is a magnetic built into the cylinder. Do not bring magnetic disks, cards, or tapes near the cylinder. Data may be lost. If the cylinder is operated vertically with heavy loads, measures must be taken to prevent rapid advancement of the piston rod when starting to operate in the downward direction. If the cylinder is operated vertically with heavy loads at the same pressure for both upward and downward directions, the starting speed in the downward direction may be highter than the speed controlled with a speed controller. In such cases, use a dual pressure control circuit as an pneumatic circuit. Example) Model MGF MGF MGF Bolt M8 x 1.2 M x 1. M12 x 1.7 Maximum tightening torque (N m) 18 6 6 l 7. Avoid use in environments where a cylinder will come in contact with coolants, cutting oil, water, adhesive matter, or dust, etc. Also avoid operation with compressed air that contains drain or foreign matter, etc. Foreign matter or liquids on the cylinder s interior or exterior can wash out the lubricating grease, which can lead to deterioration and damage of bearing sliding parts and seal materials, causing a danger of malfunction. When operating in locations with exposure to water and oil, or in dusty locations, provide protection such as a cover to prevent direct contact with the cylinder and operate with clean compressed air. When mounting a workpiece to the cylinder, do so only when the piston is retracted. Also make sure that the rotational torque applied to the cylinder body does not exceed the allowable rotational torque (given on page ). (Otherwise, the excessive rotational torque will damage the non-rotating mechanism and lead to a malfunction.)
