Metric & Inch Size

Bronze CuSn8P flange with wrapped bushing, featuring lubrication holes for optimal grease retention and minimized maintenance requirements.

Flange Bronze Bushing

Flanged bronze bushings typically feature a flange that can be fixed to specific parts of a machine. The bronze material provides excellent wear resistance and self-lubricating properties.

Wrapped bronze bearing

Wrapped bronze bearings are self-lubricating bearings where the bronze layer is wrapped around the outer or inner ring to reduce friction and wear.

Oilless thrust washer

Oilless thrust washers CuZn25Al5 are designed to operate without lubrication, usually made from wear-resistant materials such as bronze with graphite plugged.

Oilless wear Plate

Oilless wear plates are used to withstand sliding or rolling contact without additional lubrication, commonly used in sliding doors, guide rails, and similar applications.

Oilless Bushing

Oilless bronze bushings, solid bushing, bronze with lubricant plugs embedded are self-lubricating bearings that can operate effectively even without lubrication. Other commonly used bronze alloys: CuAl10Ni, CuSn12Pb, CuSn7ZnPb, Tin bronze, RG7 Bronze Bushing

Bronze backed bearings

Wrapped sliding bearing, bronze/PTFE sliding layer: Bronze-backed bearings have a layer of bronze on the backside, which enhances the bearing’s wear resistance and load-carrying capacity.

Stainless Steel bushings

Maintenance-free material due to the PTFE sliding layer: Stainless steel bushings offer excellent corrosion resistance and are typically used in environments where high corrosion resistance is necessary.

Thrust washer

Tin-plated steel/PTFE Thrust washers: such as steel sinter bronze with ptfe. are used to support axial loads; they can be flat or specially shaped to meet different application needs.

PreLubricating Bearings

Wrapped sliding bearing, wrapped bushing: Lubricating bearings are designed to reduce friction and wear, usually featuring oil grooves or holes to allow lubricant to reach the bearing’s friction surfaces.

Composite Bearings

Steel/POM sliding layer, DIN 1494/ISO 3547, Low-maintenance: Composite bearings are made from two or more different materials to enhance performance, such as a combination of bronze and PTFE, offering self-lubricating properties.

Bimetal bearings

Wrapped bushing, steel backing/bronze sliding layer: Bimetal bearings consist of two metal layers, usually a softer metal layer (like bronze) and a harder metal layer (like steel), to provide better wear resistance and load capacity.

Price & Delivery Time On Request, Bearings Push The Future, Power Rushed To Tomorrow. Custom Oilless Bushes

Custom oilless bushes bearings come with solid lubricant to form a permanent layer of solid lubrication film on the surface. The friction coefficient of bearings is smaller, the wear-resisting degree is higher, the service life is longer, and there is basically no need to add lubricating oil in use. Traditional Bearings Can Not Leave The Lubricating Oil When They Work. Once The Oil Is Broken, The Loss Will Increase Rapidly, The Maintenance Cost Is High And The Application Field Is Limited. Offering a number of clear advantages due to their simple design and cost effectiveness. Improve your equipment performance with Viiplus’ self-lubricating bearings.

Straight Type and flanged Oil-Free Bushing in various industries

The right lubrication for plain bearings: Although the applications for sliding bearings vary widely—from engine block bearings to mountain bike pedals—one thing remains constant: the best lubrication is the kind that isn’t needed. Securing and maintaining grease where necessary often poses challenges. Ensuring the smooth operation of the lubrication system is a significant task for both designers and users. Despite this, lubrication is essential. It allows sliding bearings to move smoothly, prevents corrosion, blocks the entry of dirt, and manages temperature increases due to friction. The variety of available lubricants, including greases, oils, and waxes, is extensive. However, sliding bearings do not require lubrication. Integrated solid lubricants ensure low friction, and their dry operation keeps dirt and dust at the bearing points minimal under any circumstances.

Oilless Bearing

Explore Our Extensive Range for Nearly Every Need Maintenance-Free Oilless Bearings at Factory Prices, Contact Us Today! An oilless sliding bearing excels in areas where lubrication is challenging or where long-term lubrication effects cannot be sustained.

What Are Self-Lubricating Bearings? In the broadest sense, machinery requires bearings to operate smoothly. Bearings are primarily categorized into rolling and sliding types.

Typical sliding bearings may seize or wear excessively under conditions of high load, specific motion types, contamination by foreign materials, temperature extremes, insufficient lubrication, and inadequate maintenance.

A self-lubricating bearing is designed to minimize or eliminate the need for lubrication. Even under harsh conditions where ordinary sliding bearings fail, self-lubricating bearings maintain optimal performance. They are noted for their resistance to wear and seizing, achieving superior mechanical performance without the need for maintenance. This makes them extremely versatile across various applications.

Bronze Plain Bearings

Our bearings are engineered with self-lubricating properties and are capable of superior performance in applications involving fluid lubrication, boundary lubrication, and dry friction, surpassing traditional plain bearings.
