Modern pneumatic and manual clamps enable fast and repeatable locking of linear guides without the risk of damaging the guiding surfaces. Solutions of this type are widely used both in industrial applications and in systems requiring high positioning accuracy.

What are linear guide clamps used for?

Linear guide clamps are responsible for:

• maintaining the position of a linear axis,
• increasing guide system rigidity,
• eliminating micro-movements and vibrations,
• locking movement during operation or maintenance,
• stabilizing moving components,
• protecting vertical axes against falling.

Clamps can be used with both profile rail guides and linear shafts from various manufacturers, including HIWIN, THK, INA, SKF, and Bosch Rexroth.

Pneumatic Clamps for Linear Guides

Pneumatic clamps use compressed air to activate the clamping mechanism. This enables fast, repeatable, and automatic locking of linear axes in industrial systems.

Main advantages of pneumatic clamps:

• high holding force,
• fast response time,
• easy integration with machine automation systems,
• high durability and resistance to intensive operation,
• precise axis positioning,
• compact design.

Pneumatic clamps are very often used in CNC machines, pick&place systems, robotics, and automated production lines. Popular solutions include Zimmer pneumatic clamps based on a wedge mechanism that provides high holding force and excellent system rigidity.

Manual Clamps for Linear Guides and Shafts

Manual clamps are designed for manual locking of linear axis movement. This solution is especially appreciated in applications requiring ease of use, low operating costs, and occasional positioning.

Most commonly used in:

• assembly stations,
• manual adjustment systems,
• semi-automatic machines,
• service and auxiliary applications.

Manual clamps feature a simple design, easy installation, and quick locking of linear guides or shafts without the need for pneumatic power supply.

Clamps for Profile Rail Guides and Linear Shafts

Depending on the application type, clamps can be designed for:

• profile rail guides,
• round and shaft linear guides,
• linear modules,
• vertical and horizontal axes,
• positioning systems.

A properly selected clamp increases the rigidity of the entire linear system, improves positioning accuracy, and reduces the risk of uncontrolled axis movement.

Main Features of Linear Clamps

• high operating precision,
• high holding force,
• compact dimensions,
• easy integration with automation systems,
• compatibility with popular linear guides,
• resistance to intensive industrial operation.

Depending on the design, clamps may operate manually, pneumatically, hydraulically, or electrically. Solutions combining clamping and braking functions are also available.

FAQ – Frequently Asked Questions

What is a linear guide clamp used for?

A clamp is used for locking, positioning, and increasing the rigidity of a linear axis.

What is the difference between a clamp and a linear brake?

A clamp is mainly responsible for stable positioning and motion locking, while a brake is designed for dynamic stopping and safety functions.

Where are pneumatic clamps used?

Most commonly in industrial automation, robotics, CNC machinery, and linear systems requiring automatic axis locking.

How to choose a clamp for a linear guide?

The selection depends on the guide type, rail size, required holding force, and application type.
