The different designs of maintenance free radial spherical plain bearings are listed in table 3. Their design depends on the size and series, with the main differences being the material or the design of the outer ring.

A characteristic feature of steel/steel radial spherical plain bearings is the outer ring, which is intentionally fractured so that it can be sprung apart to enable the inner ring to be inserted (fig.1). Therefore, these bearings are non-separable and easy to handle.

-> Clear discolouration and fusion is visible on the sliding layer of the seized bearing shells. The crack formation is above all recognisable in the area of the edge.

Steel/steel bearings ( fig. 6) are typically used in applications where operating temperatures or load frequencies are high, or where heavy or shock loads occur. The sliding surface of the inner ring is hard chromium plated and coated with a lithium base grease. To operate properly, steel/steel bearings must be provided with an adequate supply of lubricant. Depending on the operating conditions, the sliding surface of the outer ring may be equipped with various multi-groove patterns (figs. 7 and 8).

Heavy-duty spherical plain bearings (fig. 2) are manufactured with the multi groove system and are fitted with a LS heavy-duty (triple-lip) seal on both sides (fig. 3). As their name implies, these bearings are an excellent solution for applications under extreme environments and operating conditions such as:

As their name implies, the sliding contact surfaces of angular contact spherical plain bearings are spherical in shape and inclined at an angle to the bearing axis (fig. 1). Consequently, these bearings are well suited for accommodating combined (radial and axial) loads. Single angular contact spherical plain bearings can only accommodate axial loads acting in one direction. These bearings can be separated, enabling the rings to be mounted separately.

The permissible operating temperature range of maintenance-free radial spherical plain bearings depends on the sliding contact surface combination and the material of the seals ( table 3). However, if the load carrying capacity of the bearings is to be fully exploited, the temperature range must be narrowed. Depending on the application, it is possible to operate at temperatures above the upper limit for brief periods.

Overheating damage is the result of dramatic temperature development in the engine bearing shell, which goes hand-inhand with acute mixed friction. This is why heat cracks, discolouration and fusing are also always displayed for initial rubbing marks or seizure. The heat dissipation provided by the lubricant plays a central role here. If heat dissipation is no longer provided, this causes complete failure. Even with the initial signs of overheating, local changes to the microstructure occur and the integrity of the material is reduced. Heat cracks form at the affected areas.

The dimensions of metric maintenance-free radial spherical plain bearings are in accordance with ISO 12240-1:1998. The dimensions of inch bearings in the GEZ series are in accordance with ANSI/ABMA Std. 22.2-1988.

A standard assortment of heavy-duty spherical plain bearings is listed in the product table. On request, NEWORLD can manufacture and supply also other radial spherical plain bearings with the multi-groove system (designation suffix ESL).

The inner and outer rings of NEWORLD angular contact spherical plain bearings are made of bearing steel that has been through-hardened and ground. The sliding layer of fibre reinforced polymer, containing PTFE, is injection moulded onto the outer ring (fig. 4).

Radial spherical plain bearings have an inner ring with a sphered convex outside diameter and an outer ring with a correspondingly sphered but concave inside surface. Their design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing have to be accommodated, or where oscillating or recurrent tilting or slewing movements must be possible at relatively slow sliding speeds, often accompanied with heavy loads.

Spherical plain bearings with a steel/PTFE FRP sliding contact surface combination can be used for operating temperatures ranging from –40 to +75 °C. For brief periods, temperatures up to 110 °C can be tolerated, however keep in mind that the load carrying capacity of the bearing will be reduced at temperatures that exceed 50 °C. For additional information, contact the NEWORLD application engineering service.

of –50 to +200 °C, but their load carrying capacity will be reduced at temperatures above +150 °C. Bearings for higher temperature applications up to 300 °C, can be produced on request.

Depending on the bore diameter, metric bearings with a 2RS suffix have a double-lip seal made of a polyester elastomer or acrylonitrile-butadiene rubber on both sides of the bearing. Inch bearings with a 2RS suffix have a double-lip seal made of polyurethane on both sides of the bearing.

The bearings are manganese phosphated and the sliding contact surface is then treated with a running-in lubricant. This reduces friction and wear during the running-in period. To facilitate lubrication, all bearings, with the exception of some small sizes, have an annular groove and two lubrication holes in both the inner and outer rings.

Rod Seals are primarily used in pneumatic and hydraulic cylinders and have the task of sealing the incoming and outgoing cylinder rod.

The dimensions of spherical plain bearings in the GE, GEH and GEG series are in accordance with ISO 12240-1:1998. Bearings in the GEM series, which have an extended inner ring, have a non-standard inner

ring width, but otherwise have the same dimensions as GE series bearings. Inch spherical plain bearings in the GEZ series are in accordance with the American Standard ANSI/ABMA Std. 22.2-1988.

Upon request, inch steel/steel angular contact spherical plain bearings are also available as double direction angular contact spherical plain bearings. Double direction bearings can be used instead of two angular contact bearings in a face-to face arrangement, or as a high capacity radial bearing. Double direction angular contact spherical plain bearings consist of two outer rings and a standard inner ring. NEWORLD supplies these bearings with (GEZPR .. S series) or without (GEZP .. S series) a shim between the two outer rings. The shim simplifies installation and optimizes axial internal clearance within the bearing (fig. 9).

The radial load component of a combined load should not exceed 50% of the axial load component. When radial loads are larger, it is advisable to combine thrust bearings with radial bearings in the GE dimension series ( fig. 2). Thrust spherical plain bearings are separable, e.g. shaft and housing washers can be mounted separately.
