How to order

Master Cylinder (Robot Side)
Model KWRY0010-M handles a payload of 3 kg.
Models KWR0070-M, KWR0120-M, KWR0250-M, and KWR0500-M handle payloads of 7 kg, 12 kg, 25 kg, and 50 kg respectively.

Tool Adapter (Gripper Side)
Model KWRY0010-T corresponds to the 3 kg payload.
Models KWR0070-T, KWR0120-T, KWR0250-T, and KWR0500-T correspond to payloads from 7 kg to 50 kg.

Payload at 0.5 MPa

001 = 3 kg
007 = 7 kg
012 = 12 kg
025 = 25 kg
050 = 50 kg

Port Option (Applicable to Master Cylinder Only)
Leave the field blank for no port
Use code F for a seat check port
Use code A for an air blow port

1 Please consider both the payload and allowable static moment when selecting the product.
2 It indicates holding force when air pressure becomes 0MPa after connecting and may not meet the specification.
Use the product within the Allowable Static Moment. Operating it at the Maximum Load Moment does not satisfy the specifications.
4 The mass of product is without options.
