Description

30mm Diameter Hollow Hardened Ground Bearing Linear Shafts are specialised CF60 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 Hollow Hardened Ground Bearing Linear Shafts offer unparalleled performance and longevity.

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 h7 (+0,-0.018 to -0.021mm), 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 +/- 0.5mm 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 Hollow Hardened Ground Bearing Linear Shafts are a versatile solution for various mechanical needs, being hollow they are especially suited for where weight is a premium. 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.

Pros and Cons

Use these Hollow Hardened Ground Bearing Linear Shafts where corrosion resistance is not required and weight is a premium. If corrosion resistance is required use Chrome Plated Solid Hardened Ground Bearing Linear Shafts. If weight is not a premium use Solid Hardened Ground Bearing Linear Shafts.

Pros Cons
  • Weight Reduction: Hollow shafts are lighter than solid shafts of the same diameter. This can be beneficial in applications where weight is a premium, such as in aerospace or certain automotive applications.
  • Rotational Applications: In applications where the shaft needs to rotate at high speeds, a hollow shaft can reduce the moment of inertia, making it easier to accelerate and decelerate.
  • Deflection Considerations: Hollow shafts, when compared to solid shafts of identical diameter, exhibit reduced deflection due to their inherent weight. In scenarios where the shaft is horizontally oriented and minimal to no external load is anticipated, hollow shafts offer superior resistance to sagging. However, as the magnitude of the applied load escalates, there’s a threshold beyond which solid shafts become the preferable choice for optimal performance.
  • Diameter Tolerance: Our Hollow Linear Shafts still have a very good diameter tolerance but it is slightly lower than our solid induction hardened shafts: h7 (+0,-0.018 to -0.021mm) vs h6 (+0,-0.011 to -0.013mm)
  • Straightness Tolerance: Our Hollow Linear Shafts still have a very good straightness tolerance but it is slightly lower than our solid induction hardened shafts: (+/-0.1 to +/-0.2mm) vs (+/-0.2 to +/-0.3mm)
  • Deflection Considerations: For heavy loads solid shafts become the preferable choice for optimal performance.
  • Cost: Hollow shafts cost roughly 50% more than our solid shafts.

Application

Linear Shafts are engineered for versatility and reliability, making them suitable for a wide array of industrial applications. These shafts excel in precision environments such as automated machinery, robotics, and CNC machines, where their high surface hardness and tight diameter tolerance ensure smooth and consistent performance. Additionally, they are ideal for use in linear motion systems with ball bearings and rollers, guide shafts with plain bearings, stretch and guide rollers, and hinge pins. Their robust construction and exceptional wear resistance make them a dependable choice for demanding applications in the automotive, aerospace, and manufacturing sectors. Whether for heavy-duty machinery or delicate precision equipment, these linear shafts deliver unparalleled performance and longevity.

Customisations

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

1.0 – 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.
