Technical Specifications

Dimensions

The SN217, SN218, and SN219 series have specific dimensions that are carefully designed to ensure compatibility with different shafts and machinery. The SN217 has a bore diameter suitable for medium - sized shafts, while the SN218 and SN219 have slightly larger bore diameters, allowing them to accommodate larger shafts. This range of sizes makes it possible to choose the most appropriate bearing housing for a particular application.

Material and Construction

These pillow block bearings are made from high - quality materials. The housing is typically constructed from cast iron or steel, which provides high strength and durability. The internal components, such as the bearing inserts, are made from special alloys that can withstand high loads and friction. The precision machining of these components ensures a perfect fit and smooth operation.

Key Features

Corrosion Resistance

One of the significant features of these bearing housings is their corrosion - resistant property. In industrial environments, bearings are often exposed to moisture, chemicals, and other corrosive substances. The surface treatment of these bearing housings, such as galvanizing or painting, protects them from rust and corrosion, extending their service life.

High - Temperature Resistance

They can operate effectively in high - temperature environments. The materials used in their construction are selected to withstand elevated temperatures without losing their mechanical properties. This makes them suitable for applications in industries such as steel manufacturing, glass production, and automotive engines, where high temperatures are common.

High - Speed Capability

These pillow block bearings are designed to handle high - speed rotations. The internal design of the bearing inserts reduces friction and heat generation, allowing the bearings to operate smoothly at high speeds. This is crucial for applications such as machine tools, pumps, and fans, where high - speed operation is required.

Application Areas

Industrial Machinery

In industrial machinery, these bearing housings are used in conveyor systems, where they support the rotating shafts that move materials. They are also used in printing presses, where high - speed and precise rotation are essential for accurate printing.

Agricultural Equipment

Agricultural machinery, such as tractors and harvesters, also benefit from these bearings. They provide reliable support for the rotating components in these machines, ensuring smooth operation in harsh agricultural environments.

Automotive Industry

In the automotive industry, these bearings can be found in various parts of the vehicle, such as the engine, transmission, and wheels. Their high - performance characteristics contribute to the overall reliability and efficiency of the vehicle.

Installation and Maintenance

Installation

Installing these pillow block bearings is relatively straightforward. However, it is important to follow the manufacturer's instructions carefully. The housing should be properly aligned with the shaft, and the bearing inserts should be installed with the correct tools to ensure a proper fit.

Maintenance

Regular maintenance is essential to ensure the long - term performance of these bearings. This includes regular cleaning to remove dirt and debris, lubrication to reduce friction, and inspection for signs of wear or damage. By following a proper maintenance schedule, the service life of these bearing housings can be significantly extended.

The NSK, NTN, Fyh, NACHI, Asahi, and SKF pillow block bearings in the SN217, SN218, and SN219 series offer a combination of high - quality brands, excellent technical specifications, and outstanding features. They are suitable for a wide range of applications and can provide reliable performance in various industrial environments.
