프로파일형 레일 가이드

The dynamic load limit is the maximum load which should be applied to the carriage/pillowblock.

Tolerance describes the tolerance on 'H' as a function of carriage - rail assembly, measured from nominal dimensions.

Ball
Ball bearings used as the rolling element, standard profile rail design.

Roller
​Cylindrical rolling elements.  Increased load capacity and rigidity over ball bearing style.  Only available with a preload. (500 Series Only)

Ball Cage
Ball bearings separated by a retaining cage.  Increased running smoothness and lower noise at high speeds. (400 Series Only)

See images below

500 Series Ball
Double backed ball arrangement.  High accuracy and rigidity.

500 Series Roller
Double backed cylindrical roller arrangement.  Highest load capacity, accuracy, and rigidity of profile rail style product.

400 Series
Double faced ball arrangement.  Transport grade product that meets the needs of most applications.

MicroGuide
Miniature style profile rail.  Stainless steel construction in industry standard sizes.  Available in 5mm up to 15mm.

AccuMini
Miniature style profile rail.  Stainless steel construction.  Available in 10mm, 15mm, and 20mm.

Carriage preload eliminates internal clearances between the rail and carriage, minimizing elastic deformation caused by external forces, resulting in increased rigidity and zero backlash.

C = Dynamic load capacity

Plating options available on the carriage and rail.  Hard Chrome Plating is standard, but other options are available.  Please contact Thomson customer support for more information.

Additional Rubber Wiper
 

Metal Scraper
The Type 531 ZZ Metal Scraper made of stainless steel, serves as an added protection to the seal lips against large dirt particles, metal shavings or chips. Large contaminants are easily pushed away providing an extra level of protection to the seal lips. The Metal Scraper is easily installed in conjunction with the other optional modular accessories providing you with an easy upgrade to the standard seal. These can be easily installed on-site in the field or can be supplied from the factory.

Bellows Clips
Standard bellows are available for all assemblies. The bellows cover the entire length of the rail. The bellows are used to provide additional protection against dirt, dust and splashed liquids. Installation is simple and requires little time. Retrofitting is possible when the rail ends are drilled for the attachment of the end plate 531. Bellows are available in three styles:

• Type B “Low Profile” with outside dimensions that do not exceed the carriage
• Type C “High Compression”
• Type W “Walk On” capable of handling the harshest environments with a 90 kg load bearing capacity
• The bellow can be easily installed in conjunction with other optional modular seals providing you with a simple upgrade to the standard seal. These can be installed on-site in the field or can be supplied from the factory.

Long Life Lube Block
The 531 LL Lube Block is a solid lubricant that is a mixture of polymers, oils and selected additives that reduce the penetration of dirt, grit, and liquids into the ball path, preventing premature failures. The oil diffuses, lubricating the ball path surfaces by capillary action. Additional oil is supplied to the ball path surfaces from the polymer. For additional protection the assembly is packed with EP2 grease. There is no need for maintenance or additional lubrication during the life of the Lube Block filled bearing. The 531 LL Lube Block can be easily installed in conjunction with the other optional modular accessories providing an easy upgrade to the standard seal. These can be easily installed on-site in the field or can be supplied from the factory.

Oil Reservoir
The Type 531 OW oil reservoir is a cost effective, automatic lubrication system. It is constructed with an integrated oil reservoir that provides a uniform, consistent lubricating oil to the ball paths for extended periods of time. The Type 531 OW oil reservoir lubrication plate eliminates the need for a routine maintenance schedule, assures lubrication gets to the required points, can be refilled if required, and can operate up to 5000 km of travel. The Type 531 OW oil reservoir can be easily installed in conjunction with other optional modular accessories providing an easy upgrade to the standard seals. These can be easily installed on-site in the field or can be supplied from the factory.

Low Drag Seal

Additional features machined into carriage or rail.  Please see Thomson Profile Rail Linear Guides catalog for machining details.

Standard carriages are sold with oil preservative to protect the balls from corrosion during storage and transit. The carriages are available with the following assortment of lubricants. Additional greases are available upon request, please consult Thomson Application Engineering.
