The world leader in Linear Motion (LM) technology, THK Co. Ltd Japan, also supplies its LM Guide with Caged Ball Technology, which provides significant performance improvement over conventional products.

1. QUIET OPERATION THAT MINIMISES METAL CONTACT

Traditionally ball bearings in their initial stage of development were not caged, resulting in high noise levels, short service life and lack of performance at high rotating speeds.

The Caged Ball LM Guide boasts a long service life and superior high-speed performance in the same manner as roller bearings, while reducing the maintenance needed.

2. ORDERLY BALL MOVEMENT

The standard LM Guides consists of four rows of balls that recirculate within the LM block onto the LM rail with ball-to-ball contact whilst running on the raceways of a particular LM Rail. This results in a shortage of grease life, therefore, shortening the service life.

Caged Ball LM Guides consist of four rows of balls that recirculate within the LM block, onto the LM rail with no ball-to-ball contact whilst running on the raceways of a particular LM Rail. Hence Caged Ball technology.

The Caged Ball technology has the benefit of an absence of collision noise between the balls for quiet operation. Furthermore, an orderly ball movement with accurate alignment of balls as well as stable movement due to the elimination of sudden variations in friction.

3. ORIGINAL CAGE STRUCTURE EXHIBITING EXCELLENT HIGH-SPEED PERFORMANCE

A cage structure results in high-speed performance as the use of balls eliminates heat generation caused by friction.

4. GREASE HOLDING STRUCTURE (CONSECUTIVE GREASE POCKETS) FOR LONG-TERM, MAINTENANCE-FREE OPERATION, LONG SERVICE LIFE

Grease holding structures (consecutive grease pockets) constantly provide lubrication to ensure long-term, maintenance-free operation and a long service life.

Many bearing resellers have the common problem of identifying THK’s model number of a particular LM (Linear Motion) Guide System from the product’s model number.

The serial number, located at the top of the block, is usually mistaken for the model number.

The model number however is located on the side of the LM Block (opposite the ground reference surface section on the one side of the LM Block) with THK’s distinctive logo on the left followed by the model type on the right.

TO ACCURATELY IDENTIFY THK’S PRODUCT MODELS, RESELLERS HAVE TO TAKE NOTE OF THE FOLLOWING:

M Value [the dimension from the bottom of the rail to the top of the block]

W Value [the dimensional width of the block

L Value [the dimensional length of the block

B (width) [the dimensional bolt hole pitch in line with the width of the LM Block)

C (length) [the dimensional bolt hole pitch in line with the length of the LM Block]

S Value [the bolt value]

K Value [the dimensional height of the LM Block]

Using these values will guarantee the correct identification of your LM Guide model series and ensure that your supplier delivers the accurate product as needed.
