In 1968, R&I Manufacturing Company started out with a single product called the DURA-SLIDE linear positioning device. It was a tough, economical unit designed for the small parts assembly operation. Since then, the product line has grown, along with the company's reputation for high-quality, low-cost part placement devices.

From automatic parts to intricate electronic components, R & I grippers, escapements, slides and pick-and-place units work hand-in-hand with the leading names in the automatic assembly business.

DURA-GRIP Angular Grippers

DURA-GRIP Part Placement Devices are designed to provide a low cost gripping unit for use on transfer mechanisms. These air operated units grip parts internally or externally offering the designer a wide latitude in finger tooling arrangements.

Available in two or three finger grip models, DURA-GRIP units are ruggedly constructed with a minimum of moving parts. Utility tapped holes permit mounting the unit from the top or the side with additional cap styles for dovetail mounting. These same holes can be used to mount "stripper" devices too. All units are shipped completely assembled, ready for mounting and attaching tooling.

DURA-GRIP Parallel Grippers

The air actuated Parallel Grippers are self-centering, and allow a single finger design to handle a "Family of Parts", various sizes and or diameters. The fingers are fully guided through the entire stroke.

The fingers are thru hardened and ground tool steel. They are actuated by a sleeve roller, running in a 45¡ groove. The sleeve shaft is double end supported.

The Grippers are available in:
• English or Metric
• Finger position, opening/closing adjustable stops
• Plain or dove tail top caps
• Stripper mounting holes are standard on both sides
• Special designs or modifications available upon request

DURA-SLIDE Linear Slides

• Non-powered Linear Slides - Linear positioning devices
• Air Slides - Pneumatic linear positioning
• Air Shuttles - 2 and 3 position shuttling devices.

DURA-TRANS Bi-Directional Transfer

Bidirectional Transfer Device provides a practical low-cost method for automatic work positioning. The unit is extremely compact and eliminates the need for complex, expensive work positioning mechanisms. The DURA-TRANS unit that provides the horizontal motion has been tested under actual operating conditions with up to 160 million inches accumulated travel with negligible wear.

DURA-TAC Rotary Actuators

DURA-TAC is R&I Manufacturing's line of Rotary Actuators offering the high quality construction and durability expected by the automation industry.

The DURA-TAC line offers both economic and premier rotary actuators with many features to meet a wide range of design requirements.

Dura-Tac Rotary Actuators can be used for:
• as a rotary escapement
• as a rotary transfer
• for rotary motion
• as an orienting device
• as an air-operated change position device

DURA-TRANS Pick and Place

Pick-and-Place Transfer Device is designed to provide an economical and efficient part transfer mechanism. Sturdy and compact in construction, the unit is operated by a pneumatic rotary actuator controlled by a 4-way air control valve. The unique slotted cam with three cam followers provides a smooth transition of rotary motion to linear movement.
