Hardened Ground Bearing Linear Shafts are specialised CF53 steel shafts with an induction-hardened outer layer, designed for linear motion applications. Often referred to as linear or precision shafts, these components are integral to various mechanical systems. Characterised by their high material quality, surface hardness, and precise dimensions, they provide a robust and wear-resistant solution for linear motion. Whether used as linear shafts with ball bearings and rollers, guide shafts with plain bearings, or in other mechanical applications, these Hardened Ground Bearing Linear Shafts offer unparalleled performance and longevity.

Hardened Ground Bearing Linear Description

Choosing the right Linear Shaft

Use these Solid Hardened Ground Bearing Linear Shafts where corrosion resistance is not required and weight is not a premium.

If corrosion resistance is required use Chrome Plated Solid Hardened Ground Bearing Linear Shafts
If weight is a premium use Hollow Hardened Ground Bearing Linear Shafts

Pros

Cost-Effective: Among the 3 types of linear shafts we stock, solid shafts present the most budget-friendly option. Chrome Plated Linear Shafts are 20% more and Hollow Linear Shafts are 50% more.
Enhanced Durability: Compared to Chrome Plated Linear Shafts the induction-hardened surface makes them less susceptible to scratches or damages, ensuring a longer lifespan.
Diameter Tolerance: Our Solid Linear Shafts have the highest diameter tolerance: h6 (+0,-0.008 to -0.013mm)
Deflection Considerations: Compared to Hollow Linear Shafts, in scenarios where the shaft is horizontally oriented, as the magnitude of the applied load escalates, solid shafts become the preferable choice for optimal performance.

Cons

Corrosion Resistance: Compared to Chrome Plated Linear Shafts, they do not offer protection against rust and corrosion. This may be important when used in environments where exposed to moisture, chemicals, or other corrosive elements.
Cleanliness: Compared to Chrome Plated Linear Shafts they may accumulate more dirt, grime, or other contaminants. This can be important in industries where cleanliness is crucial, such as in food processing or medical applications.
Weight: Compared to Hollow Linear Shafts, they may not be suitable in situations where weight is a premium, such as in aerospace or certain automotive applications.

Key Features

Material: Made from CF53 Steel a high-grade carbon steel known for its exceptional strength and resilience. Its unique composition offers excellent wear resistance and toughness, making it an ideal choice for Hardened Ground Bearing Linear Shafts.
Surface Hardness: The Hardened Ground Bearing Linear Shafts boast a minimum surface hardness of 59HRC, a feature that contributes to their exceptional wear resistance. This level of hardness not only enhances the shaft’s durability but also ensures consistent performance under demanding conditions, making them suitable for various industrial applications.
Diameter Tolerance: Precision engineered with a diameter tolerance of h6 (+0,-0.008 to -0.013mm), these shafts are meticulously crafted to meet exact specifications. This tight tolerance ensures a perfect fit and alignment within mechanical systems, providing smooth operation and reducing the risk of wear and failure.

Cut-to-Size: Cut to +/- 0.2mm with manual deburring for a perfect finish, each shaft is tailored to your exact requirements. We charge per millimetre, with no additional cutting fees. This approach provides a cost-effective solution so you receive your Linear Shafts project ready.
Versatility: Suitable for a wide range of applications, the Hardened Ground Bearing Linear Shafts are a versatile solution for various mechanical needs. Whether used as linear shafts with ball bearings and rollers, guide shafts with plain bearings, stretch and guide rollers, hinge pins, or other general mechanical applications, these shafts are designed to adapt to diverse requirements. Their robust construction and precision engineering make them an ideal choice for industries seeking reliability and flexibility in their components.

Customisation Guide

We offer a broad selection of customisation options for our linear shafts.
Read the guidelines below for help choosing the correct customisations for your project.

1.0 - SHAFT DIAMETER

Choose from a range of shaft diameters. This diameter is the outer diameter of the shaft.

2.0 - Required Length

Required length is the total length of the linear shaft in millimetres (mm).

A liquid-cooled machine is used to cut the linear shaft. This ensures that the shaft remains cool during the cutting process, preserving the diameter tolerance.

We will manually de-burr the ends of the shaft with a small chamfer.

Please note the linear shafts are delivered with a protective oil coating. This coating is not intended as bearing lubrication. We recommend removing this coating with Isopropyl Alcohol or a similar solvent. After removal, be sure to apply an appropriate bearing grease tailored to your specific application.

If the protective oil coating is removed and the shafts are not greased accordingly, they will become vulnerable to corrosion and rust.

Loads & Deflection

The subsequent tables illustrate the maximum loads and deflections for the Hardened Ground Bearing Linear Shaft under various load conditions.

To calculate the beam deflections, the formulas provided in this resource have been used: https://mechanicalc.com/reference/beam-deflection-tables

For additional assistance, a helpful beam deflection calculator is available at: https://deflection.app/?language=en

To calculate the maximum column load, the formulas provided in this resource have been used: https://tribby3d.com/blog/column-buckling/ (A value of 1.3 has been used for K)

Please be aware that the figures provided are indicative only. They primarily consider beam/column deflection under a static load. However, real-world performance of a beam/column can also be influenced by factors such as dynamic loads, shear stress, bending stress, torsion, buckling, fatigue, resonance, and the specific material properties of the beam/column. Therefore, it is strongly advised to conduct personal design calculations and consider these additional factors to ensure the chosen profile is suitable for the specific application. Furthermore, we recommend applying appropriate safety factors for your industry to these calculated values. Common safety factors range between 2 and 3 for non-critical applications, providing an additional margin of safety against unforeseen circumstances or inaccuracies in the calculations.
