General DPN

Bishop-Wisecarver Group (BWG) has announced it has acquired Specialty Motions, Inc.’s (SMI) linear actuator product line.

Complementing BWG’s existing line of high-end linear actuators, the addition of the SMI4Motion product offering will enable BWG to expand the markets it serves by offering a wider range of linear actuators that meet the diverse requirements and product specifications of its customers.

Located in Southern California, SMI has been creating and developing motion control and automation devices, components and systems since 1990 under the same owner and management.

Its product line includes linear actuators from simple manual stages to ball screw actuators including push pull type, to multi-axis, miniature precision or high-performance customizable linear motor systems.

This extensive product offering will complement BWG’s range of belt, chain, lead screw and ball screw actuators covering applications from low load to heavy duty and from fast to slow speeds, including corrosion-resistant versions to accommodate food and laboratory applications.


“This acquisition reaffirms BWG’s commitment to offer its customers the best and most comprehensive product lines, ultimately making it easier for them to do business with BWG,” said Pamela Kan, president of Bishop-Wisecarver Group.

“We are proud to add the  SMI4Motion linear actuators to our expansive product line-up as SMI has a long-standing reputation of delivering high quality, accuracy and performance in all of its products.

“SMI linear actuators are highly customizable and follow the BWG design methodology. This broadens our capability to offer and design the most complete linear motion solution regardless of the technology.”

“We are extremely pleased to transition the SMI4Motion product line to a company that shares our same culture, history of innovation and vision,” said Thomas and Dorothy Corey of Specialty Motions, Inc.

“This is not only an exciting day for our two companies, but also for existing and future SMI4Motion customers who will benefit from the BWG umbrella and access to a more expansive linear motion product line-up.”

As part of the agreement, BWG will acquire SMI’s designed and manufactured line of linear actuators, which includes the following products:

Easy Slide Ball Slides Series
ECO33 Linear Actuator
ECO60 Linear Actuator
MP Series Linear Actuators
Simple Slide Linear Tables
Slick Stick Linear Actuator
Steady Rail Linear Stage Driven
Steady Rail Linear Stage Manual
TwinLite Linear Actuator
XLA 9 Linear Actuator
XLA 15 Linear Actuator
X-TREME Nano-Precision Linear Actuator

SMI will also transfer to BWG its SMI4Motion machine tools, tooling, equipment, inventory, supplies, and intellectual property related to the SMI linear actuators. The SMI web site and toll free number will now redirect customers to

“To ensure a seamless transition, the SMI4Motion linear actuator product lines will be integrated immediately into the BWG product line and made available to all current and future customers,” said Aldo DeAmicis, VP of Operations at Bishop-Wisecarver Group.

“We are excited to carry on SMI’s established legacy of innovative actuator designs and on-time delivery, and look forward to providing all customers of linear motion technology with the best products, service and customer support.”

New orders for SMI4Motion linear actuators are expected to ship in approximately 3 to 6 weeks for standard configurations as SMI transitions all the SMI4Motion machine tools from Corona, CA, to the BWG manufacturing facility in Pittsburg, CA. The two companies expect to complete the initial transition in August 2015.
