LoPro® – Linear Actuators

LoPro linear actuators are an actuated linear motion system based upon proven DualVee guide wheel technology for smooth and quiet motion over long lengths. Actuation options include AT series belt, ANSI roller chain, lead screw, and ball screw. LoPro linear actuators are also available in a non-actuated version. LoPro linear actuators provide a tough, cost effective, low friction, low profile modular solution, built to withstand a wide range of operating environments. Complete systems include your preference of wiper or basic wheel plates, and may be mounted or un-mounted. Support beams are available in aluminum or steel to meet application demands and to provide ease of installation. A wide variety of gantry brackets are available to form complete LoPro gantry systems.

Belt Driven Actuator Options 

LoPro belt drives are ideal for long lengths and high speeds. Belt drives feature AT style reinforced polyurethane belting. Belt drive systems may be mounted to either steel or aluminum support beams, and come with your choice of wiper wheel plate or basic wheel plate. Corrosion resistant versions are available, as are multiple wheel plates.

Chain Driven Actuator Options 

Chain drives are available with standard and corrosion resistant ANSI roller chain. The chain driven LoPro is ideal for vertical hoisting and large load actuation over long lengths. Aluminum and steel support beams may be used to mount the chain drive. Other options include basic and wiper wheel plates, with or without multiple wheel plates.

Lead Screw Actuator Options 

LoPro lead screws feature either BY or NTBY nut types to meet your backlash needs. Metric and inch leads are also available in lead accuracies to 0.0006 in/in (mm/mm). Lead screw systems may be selected with steel or aluminum support beams and with preference of basic or wiper wheel plates.

Screw Driven Actuation

Ball Screw Actuator Options 

Metric ball screw driven LoPro ball screw actuator systems are accurate to 0.004 in/ft (0.1 mm /300mm). Ball screws are available in standard and corrosion resistant forms to meet environmental constraints. Basic or wiper wheel plates may be selected, as well as steel or aluminum support beams.

Ball Screw Actuation

Wheel Plate Options LoPro Wheel Plate Assembly

There are two choices for wheel plate assemblies - wiper wheel plates and basic wheel plates. Wiper wheel plates are available with your choice of DualVee guide wheels and provide the lowest height solution. Basic wheel plates are the more economical choice and come with Integral DualVee wheels and your choice of either lubricators or wheel covers. Both the wiper wheel plate and the basic wheel plate are intended to run on track plate assemblies.

Support Beam Options Aluminum Support Beam 

Support beams are available in extruded aluminum or steel beam. The extruded aluminum beam comes with T slots for quick and easy mounting of brackets and other aluminum framing members. Steel support beams are made to ASTM A500 Grade A standards and provide a high modulus, making them a rigid mounting option.

Motor Mount Options Motor Mounts

Our new line of motor mounts is designed to fit any manufacturer's motor or gearbox.  Each motor mount is supplied as a kit, complete with shaft coupling and mounting hardware.  Standard or custom mounting solutions can be provided within five days.

Track Plate Assemblies 

Track plate assemblies combine your choice of single edge DualVee track with an easy to mount aluminum base. The aluminum base is made from high precision anodized aluminum alloy. Track plate assemblies are easily butt-jointed to provide infinite lengths.

Gantry Brackets

A wide variety of gantry brackets are available to form complete LoPro gantry systems.  The gantry bracket allows numerous gantry configurations to be built by offering flexibility in the types of LoPro systems that can be assembled together and in the relative positions and orientations of the stages to each other in the assembly.  Procedures for creating the most common stage configurations for gantry systems can be found in the LoPro Gantry System Assembly Manual. 

Custom Options

From completely custom systems to adding mounting holes, our application engineers are ready to assist you with any customization needs.

 

Questions

Has LoPro been certified for clean room use?

No. 
 

Can LoPro be readily made into a gantry type system?

Yes, there are standardized gantry adapter brackets for attaching LoPro actuators together into multi-axis solutions. Many possible configurations are possible. X-Z configurations are popular for pick and place applications. X-X’ Y configurations are used for large rectangular areas. Full 3-dimensional configurations of X-Y-Z are also possible.  Gantry bracket kits enable simple attachment configurations.
 

What is the maximum length available for a LoPro?

LoPro actuators can be made in virtually unlimited lengths. BWC has supplied LoPro belt driven actuators with 80 feet of linear travel stroke. Actuators with travel lengths of 10 feet or less are made with single piece track plates.  Actuators requiring travel lengths longer than 10 feet require multiple track plates joined together. Truck delivery methods limit complete assemblies to around 50 feet long fully assembled. When longer travel lengths are required, or when it is easier for a customer to handle and install a long system, the actuator can be supplied in sections for field assembly.
 

What accessories are available on LoPro?

There are many accessories for LoPro actuators that are designed to help save installation time. Adjustment wrenches are available to field adjust wheel plate preload to the linear guide track. Drive shaft keys are supplied on lead screw and ball screw actuators but the drive keys are optional on the belt and chain versions. Motor mounts can be provided for any motor manufacturer and are provided within the standard actuator lead-time. Gantry bracket kits allow the attachment of actuators to each other to create multi-axis solutions. Sensor mounting kits are available for mounting travel limit sensors or home switch sensors to the support beams while sensor flags can be added to the wheel plate assemblies.

 

What is the maximum operating temperature for a standard LoPro system?

A standard system is capable of operation up to 140 degrees F. However, a LoPro unit can be customized to increase its operational temperature capabilities. Please call the application engineering team for assistance.
 

Can LoPro track be plated or surface treated?

LoPro Tracks can be plated to increase corrosion resistance. Available coating/plating options include Electroless nickel, Armalloy, Black-oxide, Thin Dense Chrome, and Zinc. Please consult an Application Engineer about plating and surface treatment options.
 

What are the benefits of a chain driven system?

Chain driven systems work very well in dirty environment as well as near high temperatures such as ovens. The design also offers ease of repair.
 

What is the process used to anodize LoPro carriage plate assemblies and track plates, and what type of aluminum is used?

LoPro track and carriage plates are made from either 6005A-T5 or 6061-T6 aluminum, and are clear anodized (type II, Class I).
 

What is the highest temperature the belt can work in?

170oF is the highest temperature the belt can work in, before it begins to deform and the teeth begin to soften.
 

What are the differences between sizes 2S and 2L on belt and chain driven systems?

The 2L sprockets and pulleys have larger pitch diameters than the 2S versions:
Sprockets: 2L - 3.111 inches; 2S - 1.449 inches
Pulleys: 2L - 3.133 inches; 2S - 1.504 inches

The drive and idler end assemblies for the 2L are also larger than the 2S versions. The drive ends also differ in the shaft diameter (20mm and 12mm respectively), and shaft protrusion length (1.973 inches and 1.445 inches respectively). The 2L and 2S belts are both 16mm wide, but have different teeth pitch lengths (AT10 for the 2L, and AT5 for the 2S), as well as different load ratings. The 2L and 2S systems also use different support beams.
