Lubrication

Kawada Linear Bushings require grease or oil as lubricant for optimal operation.

Our Linear Bushings come pre-lubricated from the factory. However, you may choose to apply additional/replacement lubrication as required.

This document will cover the basic principles of Linear Bushing lubrication.

Grease Lubrication

Before mounting the product onto the LM shaft, apply grease to each row of balls inside the Guide Ball Bushing. 

Thereafter apply grease as necessary, in accordance with usage and other conditions as required,

if housing with grease nipple & channel are present as shown in Fig.1, apply grease with a grease gun,
or apply grease directly to the LM shaft, after cleaning the shaft of any debris.

We recommend using high-quality lithium-soap group grease No. 2. (aka NLGI Grade 2 Grease)

Oil Lubrication

To lubricate, apply lubricant to the LM shaft one drop at a time, as needed, or through housing with grease nipple & channel
as shown in Fig.1 , in the same manner as when lubricating with grease.

Commonly used lubricants include turbine oil, machine oil, and spindle oil.

Grease Consistency

The most commonly used greases, such as those used in automotive bearings, would use a lubricant that is NLGI grade 2,
which has the stiffness of peanut butter.

Grades within this range can operate in a higher temperature range and at higher speeds than NLGI grades 000-0.

Greases for bearings are typically NLGI grade 1,2, or 3.
