Technical Information

Applications for Different Types of Grease

Type	Product Name	Main Characteristic
Type L	ET-100K (Made by Kyodo Yushi)	Excellent heat resistance and oxidation stability. Also high adhesion and cohesion with limited spatter or leakage.
Type G	LG2 (Made by NSK Ltd.)	Suitable for clean environments due to low particle generation grease. Also good anti-rust properties.
Type H	FGL (Lubriplate)	Suitable for the pharmaceutical, food and beverage industry (NSF H-1 Reg. NO.043534).

Support Information

Reference: Tolerance Range of Linear Bushing and Shafts made by MISUMI

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

Features

Linear bushings compatible with low-temperature black chrome plating

*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.

Linear bushing model compatible with low temperature black chrome plating.

Straight Type		Compatible Inner Diameter
	Single Type	Φ3～φ30
	Double Type	Φ5～φ30
Flange Type		Compatible Inner Diameter
	Single Type	Φ6～φ30
	Double Type	Φ6～φ30

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.
