Metric Bearing Rings

Bearing rings, also known as wear rings or guide rings, are
precision-engineered components used to guide pistons and rods within hydraulic and pneumatic cylinders. Their primary function is to absorb side loads and prevent direct contact between metal components, reducing wear and protecting sealing elements from damage. Manufactured from durable, low-friction materials, bearing rings help improve operational efficiency, reduce maintenance requirements and extend the lifespan of machinery. Guide rings are commonly used alongside seals and O-rings
to provide additional stability and support within dynamic sealing systems.

There are several types of bearing rings available depending
on the operating environment and application requirements. Common options include piston wear rings, rod guide rings and split bearing rings designed for easier installation and maintenance. Materials vary depending on performance
needs, with resin fabric composite rings offering excellent load-bearing properties and low friction performance in hydraulic systems. Different thicknesses and dimensions are available to suit varying cylinder designs, operating pressures and motion
requirements. Swan Seals supplies a wide range of wear rings and guide rings suitable for industrial, hydraulic and pneumatic applications.

Bearing rings are widely used across hydraulic, pneumatic,
manufacturing and heavy engineering industries where reliable movement and component protection are essential. Wear rings are commonly fitted within hydraulic cylinders, presses, lifting equipment, agricultural machinery and industrial automation systems to guide moving parts and reduce internal wear.
By preventing metal-to-metal contact, guide rings help maintain cylinder alignment, protect sealing components and improve overall system reliability.
Their low-friction properties also contribute to smoother operation and reduced energy loss in high-performance applications.

Choosing the correct bearing ring depends on factors
including operating pressure, load requirements, temperature, speed and the type of equipment being used. Selecting the appropriate wear ring material and dimensions is essential for maintaining correct alignment and minimising component wear. For high-load hydraulic applications, durable composite guide
rings are often preferred due to their strength and wear resistance. It is also important to ensure compatibility with existing seals, cylinder dimensions and operating conditions to achieve optimal performance. Swan Seals offers a comprehensive range of bearing rings, wear rings and guide rings designed to
support a wide variety of industrial and hydraulic sealing applications.
