Hardened S45C Steel Sleeve Bearings Self-Lubricating are designed to provide exceptional durability and smooth operation in a range of industrial applications. The use of hardened S45C steel ensures high strength and rigidity, making these bearings suitable for handling heavy loads and withstanding extreme operating conditions.
The self-lubricating feature of these bearings eliminates the need for regular lubrication, greatly reducing maintenance requirements and operational costs. This is achieved through the use of special coatings or alloys that create a low-friction surface, enabling smooth sliding action even under high loads and temperatures.
The hardened steel construction also provides excellent wear resistance, ensuring a longer lifespan for the bearings. This, combined with their self-lubricating properties, makes them a reliable choice for machinery, automotive components, and other industrial equipment where smooth and efficient operation is crucial.
Wh it's in rotating equipment, conveyor systems, or any other application where metal-to-metal contact occurs, Hardened S45C Steel Sleeve Bearings Self-Lubricating offer a robust and cost-effective solution for ensuring smooth and reliable motion.
Hardened S45C steel bushings material provides a maintenance-free bearing solution,particularly with high load, intermittent and oscillating motion. Solid lubricants within the cast iron combines the high load capability with wear resistance and low friction.
This is the most economical solution of sliding bearings. It is suitable for high load low speed application where impact and dust environment working conditions existed. In addition to the initial lubricating, periodically lubricating is necessary because marginal lubricating condition can result into a short duration of the bearings. It is not recommended to be used under dry condition and a proper lubrication system must be considered when use this kind of bearings.
Hardened S45C steel bearings. The heat treatment improves the wear resistance and impact resistance of the material. Oil grooves and deposits are available depending on the requirements. The oil grooves and deposits pattern ensure the oil or grease spread evenly on the bearing surface to improve lubricating performance. Combined with self-lubricating technology, the bearing surface could be coated or embedded with solid lubricants to improve its lubricating performance.
Hardened S45C steel, High-performance steel self-lubricating bearings are made of cast iron based metal with special lubricants embedded. The base metal withstands high load and the solid lubricant plugs provide the self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/lower temperature with low speed.
