Back-up (Sendzimir mill) bearings

Back-up bearings (for Sendzimir mills) are widely used in multi-roll cold rolling mills, featuring a thick outer ring wall. Their advantages include a simple geometric design, high manufacturing precision, and superior radial load-carrying capacity. Most commonly employed in multi-roll cold mills that roll stainless steel and silicon steel strips, these bearings have recently seen expanded applications—thanks to the growing popularity of eight-roll mills—in supporting rolls of general-purpose wide and thin-plate rolling mills, thus broadening the scope of Sendzimir bearing usage. Given the substantial radial loads these bearings endure, the outer ring must be robust enough to prevent raceway fractures caused by the intense forces generated during the rolling process.

Product Description

Back-up bearings (for Sendzimir mills) are widely used in multi-roll cold rolling mills, featuring a thick outer ring wall. Their advantages include a simple geometric design, high manufacturing precision, and superior radial load-carrying capacity. Most commonly employed in multi-roll cold mills that roll stainless steel and silicon steel strips, these bearings have recently seen expanded applications—thanks to the growing popularity of eight-roll mills—in supporting rolls of general-purpose wide and thin-plate rolling mills, thus broadening the scope of Sendzimir bearing usage. Given the substantial radial loads these bearings endure, the outer ring must be robust enough to prevent raceway fractures caused by the intense forces generated during the rolling process.

Sengimil bearings feature exceptionally thick outer rings, with the primary tolerance requirement being the variation in wall thickness. When used in groups, these bearings must also be sorted according to their specific wall-thickness differences. Sefler-produced Sengimil bearings can be categorized into P4 and P2 classes according to ISO 492 standards, with each class adhering to a prescribed tolerance for wall-thickness variation, as outlined in the production agreement signed with the customer.

Frequently Asked Questions

How to choose the right deep groove ball bearing?

When selecting deep groove ball bearings, there are several key factors to consider. First is the load requirement—make sure you understand how much load the equipment will experience during operation. Second, rotational speed is another critical factor; ensure the chosen bearing can handle the expected speed without issues. Additionally, environmental conditions such as temperature and humidity will also influence your bearing selection.

What is a deep groove ball bearing?

Simply put, a deep-groove ball bearing is a type of rolling bearing with a deep raceway, consisting primarily of an inner ring, an outer ring, steel balls, and a retainer. Its design enables it to handle both radial loads and moderate axial loads, making it widely used in a variety of mechanical applications.

Fault Diagnosis of Thin-Wall Bearings

If the thin-wall bearing exhibits unusual noises or vibrations, users should promptly perform a fault diagnosis. Common issues include insufficient lubrication, overload conditions, and improper installation. Regular inspections and maintenance can effectively prevent major failures from occurring.

Lubrication methods for thin-walled bearings

Lubrication is key to ensuring the smooth operation of thin-wall bearings. Common lubrication methods include oil lubrication and grease lubrication. Oil lubrication is ideal for high-speed and high-temperature applications, while grease lubrication is better suited for low-speed and sealed environments. Choosing the right lubrication method can significantly enhance the efficiency of thin-wall bearings.

Installation precautions for thin-wall bearings

When installing thin-wall bearings, many users may overlook certain details. First, make sure the mating surfaces are smooth and free of damage before installation to prevent any harm to the bearing during the process. Additionally, be sure to use specialized tools during installation—avoid pressing the bearing directly with your hands, as this could lead to unnecessary deformation.

How can the lifespan of thin-walled bearings be extended?

To extend the service life of thin-walled bearings, start by ensuring that the operating environment remains clean. Regularly cleaning and lubricating the bearings with the appropriate type of oil can significantly reduce wear. Additionally, pay attention to the proper distribution of loads and avoid overloading—both of these measures are crucial for maximizing durability.
