Features

MX Lubrication Unit

Lubrication Unit MX has a fiber pad that contains the lubricant. The capillary action allows the lubricant to reach the mating surfaces.

As a result, an oil film is always formed between the balls and the shaft, significantly extending service intervals.

If an unbalanced load is applied due to the deflection of the handles to one side of the slide guide, the phenomenon of "Ball Retainer Misalignment" may occur.

Keep this in mind when designing.

Endurance Test Result

Test Conditions

Product:

LMU12 (Linear bushing before removing the oil protection against rust.)
LMU-MX12 (Linear bushing with lubrication unit MX)

Applied Load: 206N (50% against Basic Dynamic Load Rating 412N)
Average Speed: 42 m/min (0.7 m/sec)
Stroke : 100 mm
Lubricant: Grease, initial fill (LMU-MX12 only)
Shaft Material: 52100 Bearing steel 58 HRC
24 hours, continuously operated.

With 50% of basic load rating applied for testing, the Lubrication Unit MX Type has shown a 2.5 times higherdurability performance compared to the one without the MX lubrication unit.

*The data shown above are for reference only, and are not guaranteed by the supplier

Characteristics

Extended Maintenance Period:

Long durability of lubrication performance have resulted in significant reduction of maintenance work especially with machines and equipment environments where applying grease is not easy.

Environmentally friendly system:

Proper amount of lubricant to ball rolling surface at right time makes the system environment-friendly.

Cost Advantage:

Contributes to reduction of maintenance costs and product troubles caused by failing to lubricate.

Reduced Procedural Steps

No need to fill with grease prior to use because the product is already filled with Lithium soap-based grease in addition to the built-in lubrication unit.
