Product Information

This steel rod sleeve is made of high-hardness carbon steel, processed by precision turning, polishing and anti-rust treatment. It is corrosion-resistant, deformation-resistant and high in load-bearing capacity, and can adapt to high-frequency operation and complex working conditions for a long time. Compared with traditional sleeves, this steel rod sleeve has better fit and sealing performance, which can effectively prevent the rod body from wear and rust, avoid transmission deviation caused by loose connection, and buffer the impact force during the operation of the rod body, extending the service life of the rod body and the sleeve itself.

Recommendation: When ordering the steel rod sleeve, please provide parameters such as the diameter and length of the matching rod body to ensure that the steel rod sleeve fits the rod body accurately, give full play to its core role of protection and fixation, and ensure stable and efficient equipment transmission.

Materials and Properties

Carbon Steel Series
Low-Carbon Steel (C ≤ 0.25%): Examples include Q235. Offers good ductility, suitable for cold stamping and forming. Low cost but relatively low hardness.

Medium Carbon Steel (0.25%

High Carbon Steel (C≥0.6%): e.g., GCr15, features high hardness (HRC58-60) and strong wear resistance, suitable for high-load conditions.

Core Function of Steel Bushing

Friction Control

Reduce friction and wear between the shaft and bearing housing bore, protecting expensive shaft components

Load Support

Withstand radial and axial loads, ensuring stable shaft system operation

Positioning and Guidance

Maintain precise shaft positioning and concentricity, enhancing equipment operational accuracy

Vibration Absorption

Minimize noise and vibration during mechanical operation, improving stability

Steel bushings have become one of the most widely used sliding bearing components in the mechanical field due to their high strength, wear resistance, and adaptability. Selection requires matching appropriate materials and structures based on specific operating conditions (load, rotational speed, temperature, environment) to ensure efficient and stable equipment operation. For more specialized selection guidance, refer to relevant industry standards (e.g., GB/T 12613-2002 "Sliding Bearings - Rolled Bushings") or consult a professional transmission component supplier-Zhejiang Jiesheng Transmission Co., Ltd. We provide customized solutions and technical support.

FAQ

Q: How should steel shalt sleeve be maintained on a daily basis?

A: Regular inspection bushing wear, fit clearance, and presence of cracks, deformation, etc. Ensure good lubrication and change the lubricating oil or grease regularly as required by the equipment to prevent dry friction. Keep the shaft sleeve and its surrounding area clean to prevent dust and impurities from entering the fit clearance and accelerating wear. If the shaft sleeve is found to be severely worn or damaged, it should be replaced in time to avoid affecting the overall operation of the equipment.

Q: Steel shalt sleeve custom generally what is the process?

A: First of all, you need to provide us with details of the shaft sleeve technical requirements, including size, material, precision grade, surface treatment, etc. We will design the drawings based on these requirements. After communicating and confirming with you, we will start to prepare the raw materials and carry out processing and production. During the production process, multiple quality inspection procedures will be carried out to ensure that the bushings meet the standards. After production is completed, it will be packaged and dispatched.
