Sliding Instead of Rolling
DryLin® R linear bearings work through the use of sliding elements, in contrast to the design of recirculating ball bearing systems. In practice, these iglidur® elements made of high performance polymers can be manufactured from all iglidur® materials. Thus, the DryLin® R linear technology has the advantages of all of the different iglidur® bearing materials. iglidur® J is the best material for most linear applications because of its excellent wear and low coefficient of friction. Therefore, DryLin® R linear plain bearings are designed using this material.
The Most Important Properties of DryLin® R Linear Plain Bearings:
- maintenance free
- dirt resistant
- lightweight
- extremely quiet operation
- resistant to corrosion
- high static loading capacity
- resistant to shocks and vibrations
DryLin® R linear plain bearings are designed for dry running. Dirt, dust, and other abrasive media are not drawn into the bearing surface by grease or oils.
In contrast with the recirculating ball bearings, The performance of DryLiny® R bearings is not effected by the length of travel. Therefore, there are no restrictions on minimum stroke length for DryLin® R linear bearings.

Model SB
The most widely used series. Used for heavy loads since the spherical contact area has a large width. The outer ring is split at two points, enabling the inner ring to be accommodated.
Model SA1
This type of Spherical Plain Bearing is widely used in Europe. The outer ring is split at one point, and the width and thickness are smaller than model SB. Thus, this model can be used in small space.

It has two layers - sliding layer and backing layer. Sliding layer consists of filament-wound PTFE and Synthetic fiber that has low frictional and wear-resistant performance. Backing layer consists of filament-wound fiberglass impregnated into epoxy resin. It has good load capacity with low friction and stick-slip-free operation at slow speed.
Mostuf composite bearings are filament-wound composite bearings with a self-lubricating inner surface backed with a high-strength, fiber-reinforced thermoset composite. Composite bearings are standard components for manufacturers involved in heavy industrial equipment, farm equipment, pneumatic and hydraulic cylinder manufacturers, as well as valve and actuator manufacturers. Essentially, composite bearings are ideal for high-load, low speed applications or where lubrication is difficult or costly.

RBC has been a pioneer in spherical plain bearing technology since
inventing the fractured outer race design many years ago. Since that
time, RBC has continued to introduce industry leading innovations such
as high misalignment, angular contact, extended inner ring, tapered
bore, and extended lubrication groove spherical plain bearing designs.
These advanced products are used wherever pivoting, high load bearing
applications are found. Most typically, RBC spherical plain bearings
are employed in hydraulic cylinder rod ends, vehicle suspensions,
heavy equipment articulated joints, and other severe duty uses.
Industries served include off-highway mobile construction equipment,
large agricultural machinery, mining equipment, forestry products, and
other large equipment requiring bearings that provide misalignment
capabilities while carrying high loads.

Description of bearing types
Male, female or spherical bearings are ready-to-use mechanical components, based on the journal bearing principle.
These components are used in mechanical construction to transmit static or dynamic forces at different angles.
Male and female bearings are sometimes called tips or ends.
Spherical bearings are sometimes just called bearings.
The design of bearing components is governed by the DIN / ISO 12240 standard, which also specifies the overall and interface dimensions and with neighbouring mechanical components.
Bearing components can be self-lubricating or fitted with grease nipples.
Spherical bearings supplement ball bearings or other casings in slow movements. They are also ale to withstand high loadings because of the larger surfaces in contact..
The body of spherical bearings can be made from various materials: standard steel, high grade steel, stainless steel or aluminium

They can support slight axial forces as well as radial forces and are suitable for alternating dynamic loads. Sealed spherical plain bearings are protected against contamination and spray water by lip seals. Large spherical plain bearings of d = 320 mm and above belong to the premium grade X-life.
Axial spherical plain bearings
Axial spherical plain bearings comprise shaft and housing locating washers with ELGOGLIDE®. They are preferably used to support axial forces and are suitable as support or base bearings. Large spherical plain bearings of d = 220 mm and above belong to the premium grade X-life.

deva.eco sliding bearings are thin-walled, rolled bronze parts with lubrication deposits. They can take high loads and enable compact, economic bearing design solutions.
There are three basic designs:
deva.eco 9 with rombic shaped rolled lubrication pckets. This design is mostly used in applications where nearby design elements, such as gears, are oil-lubricated. Likewise these bearings can be used with standard pumpable greases or lubrication pastes.
deva.eco 8 has lubrication pockets like deva.eco 9 but filled with solid lubricant to allow operation without additional lubrication. If higher lubrication performance is required deva.eco 7 is better suited. This type includes punched holes aslubrication deposits and is used for applications which are frequently relubricated. Due to the shape of the lubrication deposits this type is less suitable for oil lubrication.

Our metal-backed, PTFE-based (polytetrafluoroethylene) polymer bearing materials have a common structure, consisting of a steel backing bonded to a porous bronze sinter layer. This bronze sinter layer is impregnated and overlaid with the filled PTFE bearing lining.
The steel backing provides mechanical strength, while the bronze sinter layer provides a strong mechanical bond between the backing and the bearing lining. This construction promotes dimensional stability and improves thermal conductivity.
These polymer bearing linings, being predominantly PTFE, offer exceptionally low friction.
