FAQs about Ball-Lock Clamping Receptacles

Clamping force refers to the force generated when three balls pull in the Clamping Pin, pulling the plate inward.
For lock-equipped models, tensile strength refers to the maximum load that can be withstood when the Ball-lock Clamp is pulled in the locked state.
For non-locking models, the clamp will disengage if a force exceeding the clamping force is applied.
If a force exceeding the clamping force is applied, a gap may occur between the plates.

Please refer to the technical data of each product below for details.

Part Number Clamping Force (N) Tensile Strength (N)
QCBA0816A 7 7
QCBA0816B 15 15

Note: If a tensile load exceeding the clamping force is applied, the clamp may disengage.

Part Number Clamping Force (N) Tensile Strength at Failure (N) Max. Gap Between Plates (mm)
QCBAS0820A 7 1800 0.4
QCBAS0820B 15

Note: The tensile strength value applies when the safety lock is engaged.

No.
The Mechanical Strength values do not include a safety factor.
These values represent the load levels at which failure can occur and should not be considered allowable loads.

Part Number Shear Strength at Failure (N) Tensile Strength (N)

Note: The tensile strength value applies when the safety lock is engaged.

Durability testing is conducted under no-load conditions, focusing on repeated clamping and unclamping of the clamper.
The results of the durability tests are shown below for reference when evaluating product suitability.

Yes, the product can be used with a single receptacle and clamping pin set.
However, we recommend using locating pins to prevent the plate from rotating.
