Standard length ball bushing, with configurable pilot flange (circular, square or compact) that facilitates its assembly thanks to the fact that it can be screwed on. With automatic lubrication thanks to the integrated lubrication unit. Significantly extends maintenance periods for the bushing, which translates into cost reduction and time savings. Available in carbon steel or stainless steel (both hardened).

For MISUMI Linear Bushing, it is recommended to use the combination with MISUMI Shafts (hardened to g6 tolerance).

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.
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
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.
– When mounting the flanged type bushing with MX lubrication unit, do not use the lubrication housing as a pilot as shown in (2), because it may damage the housing. Instead, use the Flanged Type with Pilot as shown in (3).
– Do not disassemble the lubrication unit as this may cause failure or shorten the life of the product.

*The photo shows the condition of the shafts & linear bushings after the sliding test.
ー Low-temperature black chrome plating on linear bushings is a 5µm fluoropolymer layer chemically deposited as a black film, and it has a long-lasting rust preventive effect.
In addition, the coating is resistant to cracking from extreme and repeated bending.
ー Low-temperature black chrome-plated shafts are suitable for locations where rusting or light reflection is undesirable.
ーWhen used as an assembly with a linear shaft that is compatible with low-temperature black chromium plating, it is suitable for rust prone locations.
Note: The bore of the low-temperature chromium-plated Linear Bearing has no surface treatment.
Sliding Test Conditions
50 km sliding test was conducted with a 412 N load on the linear bushing.
No performance degradation after testing.

MISUMI linear bushings, with the exception of the MX type lubrication unit, are coated with anti-rust oil, but not with grease. By selecting the grease below, you can switch to one with grease application.
