FDA/USDA and 3A-Dairy Compliance Brochure features Linear Motion Components from LM76!
E. Longmeadow, MA -- Motion Control Components - Linear Motion Food processing and beverage plants' wash down areas are unique environments that undergo harsh treatment from high pressure washers, steam, and a multitude of caustic chemicals used in the cleaning and sanitizing production equipment. OEMs and maintenance departments need to select components that will not trap contaminating debris and can be thoroughly evacuated following Sanitation Standard Operating Procedures (SSOPs). SSOPs are detailed schedules and procedures specifying what to clean, how to clean, how often to clean, and the record keeping used for monitoring.
A helpful component selection guide from LM76, "Linear Bearings, 6 Simple Steps - FDA Compliance, Wash Down Compliance," details the linear motion components available from LM76 that are FDA/UDSA/3A-Dairy compliant.

This low profile gantry is just 141.5 mm (5.571 in.) high. The table top measures 380 mm x 380 mm (14.961 in. x 14.961 in.)
Available motor mounts include NEMA 17 and NEMA 23 mounts for steppers or servo motors with encoders. Constructed using a strong extruded alumiunm frame, the dual X axes design, and 4 precision leadscrews provides ± 50 microns of repeatability on axis.
White Paper - Life Expectancy for Single vs. Double Nuts by Steinmeyer!
Life expectancy equations provided by some manufacturers only cover nuts having two-point contact. But what about four-point nuts? And what about the effects of preload?
BURLINGTON, MA --Motion Control Components - The fundamental determining factor of life expectancy is duty cycle, which includes load, thrust, speed, and duration of the travel. Calculating these forces is commonly understood. But preload is a very important factor in ball screw life calculations and must always be considered. In cases where the applied external load is low, preload can determine as much as 90% of the life.
Steinmeyer engineers have developed a preload graph that consists of two curves: each representing the force-deflection curve of one ball nut in a double nut configuration.
Dyadic SCN6 Integrated Electric Actuators rated to 500N max. thrust!
Greenville, DE -- Motion Control - Servo2Go.com has just added remarkable new additions to its broad range of cost-effective 24V electric linear actuators from Dyadic Systems. The SCN6 series actuators are compact yet powerful integrated mechatronic cylinders that feature a motor, encoder, drive and actuator in one integral package
Dyadic Systems has developed the linear actuator drive mechanism such that the screw and nut are optimized for high accuracy, long life and low cost while delivering high speed and peak thrust.
Application - Rotary Table from Intellidrives Tackles Big Wafers!
INTELLIDRIVES's Direct drive rotary servo tables.
Philadelphia, PA, -- Motion Control Components and Systems - The ACR-335UT direct drive rotary table from IntelLiDrives adapts linear motor technology, coupled with precision bearings, to provide faster and more accurate handling of the 300 mm semiconductor wafers.
The 335 mm diameter center opening in the ACR-335UT rotary table easily accommodates large 300 mm (12 inch) semiconductor wafers, allowing for extraction of the chip dies from the wafer during semiconductor assembly manufacturing processes or dual side wafer inspection.
AB25A100 Panel Mount Servo Drive Provides Centralized Control & Offers High Bandwidth & Quick Response Times!
Greenville, DE -Motion Control Components - The AB25A100 PWM servo drive from Advanced Motion Controls is designed to drive brushless and brushed DC motors at a high switching frequency. A single red/green LED indicates operating status. The drive is fully protected against overvoltage, under-voltage, over-current, over-heating and short-circuits across motor, ground and power leads. Furthermore, the drive can interface with digital controllers or be used stand-alone, and requires only a single unregulated DC power supply. Loop gain, current limit, input gain and offset can be adjusted using 14-turn potentiometers.
Motion Control Application - A wasp shows the way!
Fall River, MA -- Motion Control Components Application - In tumor treatment, neurosurgeons today use a thin, rigid needle to inject medication into the affected brain tissue. This carries a relatively high risk of injuring healthy tissue, because a rigid needle only allows the surgeon to enter a certain region of the brain, following a straight path. The ideal solution would be a flexible operating tool.
This is where the London Imperial College comes in. In recent years, a team led by Prof. Rodriguez y Baena worked on developing a flexible robotic needle capable of reaching the deeper regions of the brain, while simultaneously avoiding especially sensitive areas. The young researchers sought to imitate the special mechanism employed by female wood wasps that use their thin but very strong drill-like stings to lay eggs inside the wood of trees.
Pegasus Series 1 Linear Bearings - For When A Linear Bearing Simply Cannot Fail!
E. Longmeadow, MA Motion -- Control Components - Linear Motion - LM76 has developed the most corrosion resistant linear bearing available. In space, deep under the sea, or in the harshest environments when there can be no "Plan B," Pegasus Series 1 Linear Ball Bearings can be counted on to perform. In some applications linear bearings will not move for days, weeks, months or even years, however, when called on to perform they must work as if they just came out of the box. LM76's Pegasus Series 1 Linear Bearings feature Silicon Nitride (SiNi) Ceramic Balls in a shell with retainer and end caps all made from 440 Stainless Steel and then ArmorloyTM coated.
Six-Axis Linear and Rotary Positioning Stage from H2W Technologies, Inc!
