Product catalog summary

Precision Parallel Grippers GPP Product Description: The GPP grippers are designed for demanding applications, capable of both internal and external gripping. They are double-acting and can be configured to open or close when depressurized. Proximity switches detect end positions, and the gripper body includes tapped holes for additional devices. Safety features include throttling orifices to prevent overloading, and high precision ball bearings ensure efficiency and reliability.

Applications: Used in revolver pivot units with rotary drives for precise workpiece handling without radial deviation.

Variants and Accessories: The GPP/GPPI/GPP-ISO grippers come in three sizes and variants, with dovetail mounting and ISO compatibility for robots. Accessories include clamping devices for proximity switches and exhaust throttles.

Gripping Force and Load Calculations: Examples of gripping force calculations for different configurations, including external and internal gripping with and without springs, are provided. Load factors and limit constants are detailed for safe operation.

Technical Specifications: Operate at pressures between 3-6 bar, with air as the medium. Feature a repeatability of ±0.005 mm and require no maintenance. Material composition includes aluminum, steel, bronze, and plastic.

Precision Parallel Mini Grippers GPPM: Designed for small parts in confined spaces, the GPPM grippers are dual-acting and feature a patented ball guide for precision and efficiency. Compressed air can be supplied in various directions to accommodate different installation requirements.

Installation and Configuration: The GPPM series can be installed using attachment drill holes or optional adapters with Quick-Set® size 20. Proximity switches can be attached to the housing using an attachment set. The GPPM-X allows air infeed and installation of proximity switches along the guide direction, while the GPPM-Y does so across the guide direction. The GPPMI variant allows air infeed from above without proximity switches.

Scope of Delivery: GPPMX and GPPMY come with a clamping device for proximity switches and two plug-type connections. GPPMI-X and GPPMI-Y include a clamping device for proximity switches.

Specifications: Available in two sizes with three variants each. Key parameters include gripping force, static forces, and load moments. Maximum permissible static forces per jaw are specified for different models.

Operating Conditions: Operating pressure ranges from 3 to 6 bar, with air as the medium, either oiled or unoiled, filtered to 5 µm. Ambient temperature should be between 10°C and 50°C, with relative humidity below 95% without condensation. Require no maintenance and have a warranty of two years from the date of delivery.

Universal Parallel Grippers (GPU/GPUI Series): Feature a robust, low-friction guide system for the jaws, utilizing cylindrical rollers for high efficiency. Compact, allowing multiple units to be mounted side by side. Offer high repeatability and gripping force relative to their weight.

Specifications: Available in four sizes, with varying gripping distances, piston diameters, and opening/closing times. Operate at pressures between 2 and 6 bar and are suitable for air, either oiled or unoiled, filtered to 5 µm.

Operating Conditions: Similar to the GPPM series, operate within a temperature range of 10°C to 50°C and require maintenance after 10 million cycles. Come with a two-year warranty.

Gripping Force Diagrams: Include diagrams illustrating the relationship between gripping force and various parameters such as pressure and distance, providing guidance on optimal operating conditions.

Long-Stroke Grippers GPL Product Description: Designed for gripping parts with varying dimensions, featuring robust, low-friction jaw guides with cylindrical rollers. Pneumatic connections and proximity switches are located on the housing's narrow side. An optional incremental encoder allows for precise finger positioning.

Applications: Can be used with proximity switches for interlocking gripping and with encoders for monitoring dimensions without complex systems.

Scope of Delivery and Accessories: Come with a clamping device for proximity switches and exhaust throttles. Special accessories and Quick-Set® are available.

Technical Specifications: Gripping force per finger (FS), static forces (Foy, Foz), and load moments (Mox, Moy, Moz) are defined with permissible values provided. Operate at 3-6 bar pressure with air filtered to 5 µm. Maintenance-free and have a 2-year warranty.

Size Variants: GPL-30-1 and GPL-40-1 offer different stroke lengths and weights, with specific opening and closing times. GPL-45-2, GPL-60-2, and GPL-75-2 provide larger stroke options and increased weight.

Universal Angular Grippers GWU/GWUI Product Description: Designed for external gripping, these grippers feature a double-acting pneumatic cylinder and jaws that open 180°, reducing handling movements. Include proximity switches and compressed-air supply on narrow sides.

Technical Specifications: GWU-16/GWUI-16 and GWU-20/GWUI-20 models offer adjustable opening angles, specific piston diameters, and operating pressures. Maintenance-free for up to 10 million cycles and have a 2-year warranty.

Load Definitions: Gripping force (FS), static forces (Foy, Foz), and load moments (Mox, Moy, Moz) are defined with permissible values for different mounting configurations.
