A plain bearing in railroading is sometimes called a solid bearing, journal bearing, or friction bearing. Journal or plain bearings consist of a shaft or journal that rotates freely in a supporting metal sleeve or shell. There are no rolling elements in these bearings.
Plain Journal Bearing, in general, is the least expensive type of bearing. They are also compact and lightweight, and they have a high load-carrying capacity.
Construction of Plain Journal Bearings
Plain journal bearings, often referred to as sleeve bearings, bushings, sliding bearings, solid bearings, or friction bearings, are simple yet highly effective mechanical components. Unlike their rolling-element counterparts, such as ball bearings and roller bearings, plain journal bearings lack rolling elements. Instead, they rely on a layer of lubrication to create a low-friction interface between the bearing and the shaft it supports.
Plain journal bearings consist of two main components: the shaft and the bearing. The shaft is the rotating component, while the bearing, typically made of a low-friction material like bronze or babbitt, is housed in a stationary structure. The bearing is precisely machined to fit the shaft diameter and incorporates lubrication grooves and oil holes for effective lubrication.
When a plain journal bearing is in operation, a lubricant film is formed between the rotating shaft and the bearing. This film prevents direct metal-to-metal contact, reducing friction and wear. The lubricant film is maintained by the hydrodynamic action, where the relative motion between the shaft and the bearing creates a pressure gradient that draws lubricant into the contact zone.
Types of Plain Journal Bearings
There are several variations of plain journal bearings, each suitable for specific applications. Some common types include:
- a. Solid Sleeve Bearings
Solid sleeve bearings are the simplest form of plain journal bearings, consisting of a solid cylindrical sleeve that fits around the shaft. They are cost-effective and suitable for low to moderate loads and speeds. - b. Split Sleeve Bearings
Split sleeve bearings are similar to solid sleeve bearings but have a longitudinal split. This split allows for easy installation and removal without the need to dismantle the entire machinery. - c. Tilting Pad Bearings
Tilting pad bearings consist of multiple individual pads that are attached to a supporting structure. These bearings can accommodate misalignments and provide increased stability and load capacity.
Where is the Plain Journal Bearing Used?
Journal Bearings are used wherever movement is required. These applications range from Home Office Solutions to Agriculture and Equipment Parts to oil-free bearings for engines. Thus, in our everyday lives, nothing would work properly without a plain bearing.
Slide Plates Used In Farming
Slide plates are typically made from durable materials such as C86300, C93200, and C95400. Their primary purpose is to enhance the overall performance and longevity of agricultural equipment.

Journal Bearing Lubrication
All rotating machinery requires lubrication in order to function properly and reduce wear and tear. One component of rotating machinery that often requires lubrication is the journal bearing. Proper lubrication of plain journal bearings has many benefits. Lubrication extends the life of the bearing by reducing wear and also helps to protect the bearing from corrosion.
Bronzeoilless.com use bronze journal bearing with graphite to achieve self-lubricating. By friction, the solid lubricant in the bore or groove is transferred or counter-transferred to the friction surface, forming a well-lubricated, firmly adhered, and uniformly covered solid transfer film, which ensures good lubrication of the friction substrate during long-term operation.
Materials In a Journal Bearing
Journal Bearing is an important part of contemporary machinery and equipment, and is a very common mechanical hardware accessory, with it for better operation, then what material for bearings?
- Brass (H62 ,H65, H68 ,H70 ,H85 ,H90)
- Tin Bronze QSn5-5-5, QSn6-6-6, CuSn10Pb1,CuSn8,CuSn4,CuSn12

Bearing alloys, bronze, aluminum-based alloys and zinc-based alloys are all known as metallic materials.
What Is The Role Of Journal Bearing?
In terms of its role, Journal Bearing is to support and support the shaft. Unlike roller and ball bearings, journal plain bearings do not have any rolling elements. As a result, they are only capable of supporting radial loads, which stem from the weight of the shaft.
Self-lubricating Journal Plain Bearings
Plain Bearings are an important part of mechanical fittings. Responsible for the transfer or counter-transfer of solid lubricant from the hole or groove to the friction surface at high speeds, a well-lubricated, firmly adhered and uniformly covered solid transfer film is formed on the friction surface, substantially reducing frictional wear.
