Low temperature black chrome plating of the linear bushings is 5μm of fluoro compound chemically on a black film, and it has a long lasting antirust effect.
Moreover, it does not crack easily and it can endure repeated bending. The combination with the low temperature black chrome plated shaft is applicable for places where rust or reflection of light is not allowed
Salt water spray testing method conforms to JIS H8502

Linear Bushings, Rounding Flanged – Single Type --
MISUMI’s Linear Bushings, except for Lubrication Unit MX type, are coated with antirust oil, but not greased.
By selecting from the following greases, you can order a greased type.
Selecting L or G type allows great reduction of the grease dispersion caused by operation. (Comparison of Dust Raise amount shown below)
H Type (NSF H-1 Attestation) can be used in the situation which have potential of contacting foods.
Safety is guaranteed even in case grease sticks to food during food processing.
|Type||Product Name||Main Features|
(Made by Kyodo Yushi)
|High heat resistance and oxidation stability. Also,superior in adhesion and cohesion with less leakage.|
(made by NSK Ltd.)
|Limited dust generation and suitable for use in clean rooms. High corrosion resistance.|
|Applicable to lubrication in machining and packaging of food,drink,and medicine .(NSF H-1 Registration No. 043534)|
Farewell to frequent lube maintenance…
Linear bushing with integrated lube unit MX at last!
The MX lube unit supplies proper amount of lubrication by capillary action of it's fiber-pad material. Re-lubrication interval is greatly extended by constantly maintaining a film of lubricant between the shaft and the ball bearings.Four merit points for the customers
|1)||Greatly extended maintenance intervals.
Extended lubrication performance means lowered maintenance loads.
|2)||Cost reduction effects.
Lowered maintenance costs and reduced troubles caused by forgetting to add lubricants.
Keeps the surroundings clean, thus environmentally friendly.
|4)||No need for initial greasing.
Initial grease application is not required since lithium soap based grease is pre-applied to the lube unit and ball bearings.
Choose from 138 combinations based on sizes, shapes and surface treatments.
Definition: Distance which 90% of tested specimen can achieve without experiencing any flaking (fish scale-like surface damages).
The rated life can be obtained by the following formula based on basic dynamic load rating and applied load on the system.
| L: Rated life (km)
C: Basic dynamic load rating
P: Applied effective load (N)
When the applied effective load on the linear system is equal to the basic dynamic load rating C, the rated life L will be 50km. Similarly, when P=0.5 * C, the L=400km.
Under the condition of P=0.5 * C endurance testing, the linear bushing with MX Lube Unit achieved durability performance three times higher than the rated life.
