Lubrication

Lubrication is essential to linear motion system. Without lubrication, the friction of rolling parts
increases and might be the main factor of service life shortening.

A lubricant :

(1) Reduces friction on moving parts, thereby to prevent wearing due to raise in temperature.
(2) Forms an oil film on rolling surfaces, thus decreasing stress that develops on the surfaces and
safeguarding the system against rolling fatigue. (3) Covers metal surfaces with an oil film, thereby preventing rust.
To tap the full function of a linear motion system, lubrication is essential to meet the system service
conditions.
※Even the linear motion system is sealed, it cannot completely prevent the leakage of lubricants no matter how negligible the amount of
leakage is at any given time. It is therefore necessary to replenish the lubricant periodically according to the operating conditions.

Classification of Lubricants

Primarily grease and sliding surface oil are used as lubricants for linear motion systems.
In general a lubricant must :
(1) Form a strong oil film.
(2) Reduce wear as much as possible.
(3) Have high wear resistance.
(4) Have high thermal stability.
(5) Be non-corrosive.
(6) Be highly rust-preventive.
(7) Be free from dust and some moisture.
(8) Be free from significant fluctuations in consistency against repeated agitation of grease.

Lubricants in General Use

Lubricant	Classification	Item
Grease	Lithium-based grease (JIS No.2) Urea-base grease (JIS No.2)	1. Daphne Eponex Grease No.2, (Idemitsu Kosan) or equivalent. 2. AFB-LF GREASE (THK ) ,It excels in extreme pressure property and mechanical stability. 3. AFA GREASE (THK), it is ideal for long-stroke, high-speed LM Guide operations.

We suggest our customer to take account of E2 self-lubricant system, E2 self-lubricating kit is run by a high oil content of reservoir and optimization of film forming design adequate and proper amount of lubricant to grooves of rails, make supplementary periodically up to 4000km, end users can install or replace E2 lubrication reservoir kit by themselves easily and directly without moving the block out. Please contact NJSKT for obtaining further information. More >>

The interchangeable type of block and rail are packed separately, Even customers instal it by themselves, They still can reach accuracy standard as expected.rnFor non-interchangeable type of block and rail, NJSKT already has implemented installation and measurements, When customers receive the product, Any improper behavior to disassemble, Interchange or change block direction will affect product warranty.

Please noted the Linear guides products have been through preservative treated before leaving our warehouse, If customers will not use the products within a month, We highly suggest our customers to do regular anti-rusty work in light of temperature in different area. More >>

We agents brands of HIWIN, CPC, TBI always provides the best solution for customers while using linear guides in particular environment such as chrome-plating process for anti-corrosion, Please contact NJSKT for immediate support for your needs. More >>

The standard applicable temperature is within -20 to 80 degree, we shold be mindful of actual temperature in where we are and choose appropriate lubricant to fill.
