MaterialCast Iron
FinishColor Coated

The NTN bearing unit is a combination of a radial ball bearing, seal, and a housing of high-grade cast iron or pressed steel, which comes in various shapes. The outer surface of the bearing and the internal surface of the housing are spherical so that the unit is self-aligning.

The inside construction of the ball bearing for the unit is such that steel balls and retainers of the same type as in series 62 and 63 of the NTN deep groove ball bearing are used. A duplex seal consisting of a combination of an oil-proof synthetic rubber seal and a slinger, unique to NTN, is provided on both sides.

Simple Yet Essential: Pillow Block Bearings

Pillow block bearings are a fundamental yet versatile component found in various machines. They provide support for rotating shafts that run parallel to the mounting surface. This seemingly simple design plays a crucial role in numerous applications, including conveyor systems, industrial fans, farm equipment, jib cranes, and even car washes.

Superior Performance and Smooth Operation

Pillow block bearings utilize rolling elements, which offer a significant advantage over linear ball bearings. The low coefficient of friction and larger rolling elements enable them to achieve speeds up to 2.5 times faster. This translates to better overall performance, smoother travel, and a reduction in both vibration and noise.

Clarification on Rolling Elements

It’s important to note that pillow block bearings themselves are not the rolling elements. They house these elements, typically ball or roller bearings, which are designed to minimize friction between a rotating shaft and the housing. These rolling elements play a vital role in reducing friction between a moving object and the supporting surface, not just vehicles on roads. Additionally, pillow block bearings can handle both radial and axial loads, ensuring proper shaft alignment and support.
