Detailed Safety Instructions

Caution

1.This product allows leakage from the lip. When selecting a product, pay attention to the following points and perform the suction test on the actual application. (1) Since the lip of the mark-free pad is made of hard resin, it reduces suction marks compared to rubber vacuum pads, but it does not completely prevent suction marks. The degree of reduction of suction marks varies depending on the environment and the workpiece. (2) Ensure that the flow rate of the vacuum source is as large as possible. Also, it cannot be used to hold a vacuum. (3) Select a sensor suitable for the operating conditions. (4) The inside of the flexible adapter of this product may wear out due to its structure and depending on usage. When using Vacuum Pads Mark-free Series in clean-room, make sure that the dust emission from the abrasion does not affect to the product and production line in advance.

2.This product has a flexible adapter with a stroke of 1 mm, but it is only intended to follow the slightest inclination of the workpiece. If a buffer function is required, it should be used in conjunction with a spring-loaded holder. When using a spring-loaded holder, please minimise the lateral force on the sliding part. Wear of the holder may cause malfunction and dust generation.

3.There is no anti-rotation structure between the flexible adapter and the resin pad. Note that this product is not suitable for rotary transport.

4.Be sure to clean the suction surface of the vacuum pad before use. Deposits may remain as suction marks. When cleaning, be careful not to scratch the suction surface, and do not use organic solvents.

5.Special stainless steel used in this product is not for the purpose of rust prevention. Rust may be generated depending on the operating environment.

6.When attaching the flexible adapter to the actual equipment or pad holder, refer to the tightening torque in the following table, tighten it using the appropriate tool, and confirm that there is no loosening.

7.The resin pad mounting screws to the flexible adapter may loosen due to creep. Check regularly and retighten to the tightening torque shown in the following table. If there is no improvement by retightening, replace it with a new resin pad.
