What is Case Hardening?

Case hardening is a heat treatment process used to selectively harden the surface of a metal, usually low-carbon steel.  The goal is to create a part with the following qualities:

  • Hard, wear-resistant surface: This outer layer offers superior resistance to scratches, abrasion, denting, and fatigue caused by repetitive stress.
  • Tough, ductile core: The inner core maintains higher ductility and toughness, providing the part with the ability to absorb impacts and resist deformation without breaking.

Benefits of Case Hardening

  • Enhanced Wear Resistance: The hardened surface dramatically improves resistance to abrasion, scratches, and indentation.
  • Improved Fatigue Strength: Case hardening helps prevent cracks from forming and propagating under repetitive stress and loads, extending the part's lifespan.
  • Maintains Core Toughness: Unlike through hardening, the core remains relatively soft, providing shock resistance and preventing catastrophic brittle fractures.
  • Cost-Effective: It's often more cost-efficient to case harden a low-carbon, less expensive steel than to use a high-carbon steel for the entire component.

Machining Considerations

  • Hardened outer surface will increase tool wear on O.D. Turning operations such as parting, grooving, facing.
  • Recommend use of specialised turning inserts (e.g. CBN Tipped inserts)
  • Suitable for griding operations (e.g. Cut-Off wheel, surface grinding flat features)
  • Ductile core allows end drilling & tapping without the need for specialised tooling.

This makes aluminum extrusions a good choice for applications where high strength is required, such as in load-bearing structures.
Corrosion resistance
Aluminum is naturally resistant to corrosion, making it a good choice for applications in harsh environments. The surface of aluminum is protected naturally through oxidation, which prevents rust. This natural protection can be enhanced by anodizing or other finishing processes. This makes aluminum extrusions a good choice for applications where exposure to moisture or chemicals is a concern.
Aluminum extrusions can be customized to meet the specific needs of an application. This is done by varying the cross-sectional shape of the extrusion, as well as the alloy and temper of the aluminum. This makes aluminum extrusions a versatile material that can be used in a wide variety of applications.
Aluminum extrusions are often a cost-effective alternative to other materials, such as steel or stainless steel. This is due to the relatively low cost of aluminum and the efficiency of the extrusion process. This makes aluminum extrusions a good choice for applications where cost is a factor.
Other benefits
In addition to the benefits mentioned above, aluminum extrusions also offer a number of other benefits, including:
Non-magnetic: Aluminum is non-magnetic, making it a good choice for applications where magnetic fields are present.
Seamless construction: Aluminum extrusions are seamless, which makes them resistant to leaks and corrosion.
Easy fabrication and assembly: Aluminum extrusions are easy to fabricate and assemble, making them a good choice for complex applications.
Aluminum profile extrusions offer a number of benefits that make them a popular choice for a wide variety of applications. If you are looking for a strong, lightweight, corrosion-resistant, and customizable material, then aluminum extrusions may be a good option for you.

Kawada Linear Bushing Lubrication Guide

Oct 2, 2021


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.
