° 45 ° 45 ° 45 ° 45 A 66 A-I-5.3 LA Series Fig. I-5•9 LA Series (1) High rigidity and high load carrying capacity A set of three ball grooves is made on both sides. This contributes to the increased rigidity and load carrying capacity. The top and bottom groove are formed in the circular arc, with a closer radius of ball, which ensures great rigidity and load carrying capacity. With the gothic-arch center groove, rigidity and load carrying capacity are further increased. (2) Moderate friction A well-balanced combination of 2-point contacts at the top and bottom grooves and 4 points contact at Fig. I-5•10 Super rigidity design the center groove provides moderate friction while ensuring rigidity by appropriate preload. (3) Load distribution four directions Contact angle is set at 45 degrees in all grooves, dispersing the load to four rows irrespective of load direction. This realizes equal rigidity and load carrying capacity in vertical and lateral directions and provides well-balanced design. (4) Strong against shock load Load from any direction, vertical and lateral, is Grinding wheel received by four rows at all times. The number of the row which receives the load is larger than in Fig. I-5•11 Rail grinding other linear guides, making this series stronger against shock load. W (5) Highly accurate Fixing the measuring rollers is easy thanks to the Master roller gothic-arch groove. Ball-groove measuring is accurate and simple. This benefits a highly precise and stable processing. (6) The dust protection design h The rail's cross section is designed as simple as possible. Furthermore, the improved seal enhances the sealing function. Inner seal is available as an option.

HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.
Trican Well Service
GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
