- 25mm Diameter 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. 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 /- 0.5mm 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 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. Pros and Cons 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 Cons 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. 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. 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.
