Quick Summary
- 1A scene from Nikolai Gogol's 'Dead Souls' features a carriage with a wooden wheel hub, representing the earliest form of a bearing.
- 2Historians date the first spoked wheels with such hubs to the third millennium BCE.
- 3By the 19th century, steel sliding bearings were already used on the Tsarskoye Selo Railway, though they were imported from England.
- 4Today, sliding bearings remain vital in industry and transport, existing in both high-tech and ancient forms.
A Literary Wheel and a Timeless Invention
The opening scene of Nikolai Gogol's Dead Souls presents a curious conversation between two peasants. They stand outside a tavern, observing the carriage of the protagonist, Chichikov. Their debate is not about the man inside, but about the vehicle itself. They question whether the carriage's wheel could make the journey to Moscow or even to Kazan. This brief, humorous exchange captures a moment in time, but it also inadvertently documents a piece of engineering history that spans millennia.
The carriage in question is a spring wagon, a vehicle typical of the provincial gentry of the era. The peasants, without needing to approach closely, can see the wheel's construction: a rim bound in leather, spokes, and a central hub. This hub, the stepitsa or wheel nave, is the focal point of the entire mechanism. It is the component that allows the wheel to turn on its axle, and it represents the very first iteration of a bearing.
The Ancient Sliding Bearing
The hub described in Gogol's work is a sliding bearing in its most primitive form. It was a wooden block, almost certainly carved from oak or elm, which fit over the axle. To reduce friction, it was lubricated with birch tar. This simple design is not unique to 19th-century Russia; it is a direct descendant of the earliest wheeled vehicles. Historians of technology generally date the first spoked wheels with this hub construction to the third millennium BCE, with some cautious estimates placing it at the turn of the third and second millennia BCE.
The fundamental components have remained consistent for thousands of years:
- A spoked wheel structure for strength and reduced weight
- A leather-bound rim acting as a primitive tire
- A central wooden hub (the bearing) that fits over the axle
This ancient design, born in the same era as early civilizations, was still in use in the Russian countryside well into the 19th century, a testament to its functional durability.

The Industrial Revolution Arrives
While Chichikov's carriage relied on a wooden hub lubricated with tar, the industrial world was already advancing. In the same historical period, a new technology had arrived in the country: the steel sliding bearing. These were not the simple wooden blocks of old, but manufactured components featuring a grease box for more effective lubrication. This innovation was critical for the new machinery of the age, enabling higher speeds and greater loads than wood could withstand.
The adoption of this technology in Russia is clearly illustrated by its use on the Tsarskoye Selo Railway. This line, connecting St. Petersburg with the imperial residence at Tsarskoye Selo, was one of the first railways in the Russian Empire. The wheels of its steam engines and passenger wagons were equipped with these advanced steel bearings. However, this progress came with a dependency; the components were not yet produced domestically and were imported from England, the epicenter of the Industrial Revolution.
A Legacy of Motion
The journey of the bearing did not end with the steam age. The sliding bearing, in both its ancient wooden form and its modern steel incarnation, continues to be a cornerstone of mechanical engineering. Its applications are vast, spanning nearly every sector of industry and transportation. The principle of a component sliding on an axle, while simple, remains effective for countless uses.
Today, the technology has evolved far beyond the wooden hubs of Gogol's characters or the early steel bearings of the Tsarskoye Selo Railway. Modern sliding bearings are crafted from high-technology materials and can feature complex, intricate designs. Yet, the original concept persists. The fundamental need to reduce friction between moving parts connects the wheeled vehicles of the third millennium BCE directly to the complex machinery of the 21st century.
From Literature to Modern Factories
The simple conversation between two peasants in Gogol's Dead Souls serves as an unexpected historical marker. It captures a transitional moment where ancient, wood-based technology coexisted with the new, steel-driven industrial world. The wheel hub, a component so fundamental it was often overlooked, is revealed as a critical piece of engineering with a history as old as civilization itself.
From the spoked wheels of ancient chariots to the high-speed trains of today, the principle of the bearing has remained essential. Its evolution from a carved wooden block to a precision-engineered steel component mirrors the broader story of human technological progress. The next time you hear the sound of a turning wheel, consider the silent, sliding bearing that makes the motion possible—a direct link to the world of Chichikov and the dawn of engineering.

Frequently Asked Questions
The article traces the history of the sliding bearing, a fundamental mechanical component. It uses a scene from Nikolai Gogol's literary work 'Dead Souls' as a starting point to explore the evolution of this technology from ancient times to the modern industrial era.
The novel's opening scene features a detailed description of a carriage wheel, including its wooden hub. This hub is identified as the earliest form of a sliding bearing, providing a literary snapshot of a technology that was thousands of years old even at the time the book was written.
The first known sliding bearings, in the form of wooden wheel hubs, date back to the third millennium BCE. Historians associate their appearance with the development of the first spoked wheels, a technology that revolutionized transportation and warfare in ancient civilizations.
The 19th century was a period of transition. While traditional wooden hubs lubricated with birch tar were still common in rural areas like those depicted by Gogol, advanced steel sliding bearings were already in use for industrial applications. These were imported from England and used on the country's first railways, such as the Tsarskoye Selo line.
