Spherical plain bearing series W steel on steel, DIN ISO 12240-1, treated with molybdenum disulphide mos2, regreasable. For use on standard hydraulic cylinders to DIN 24333 and to DIN 24336 with floor piece or piston rod relays.
GEEW…ES radial spherical plain bearings are designed for applications requiring high load-carrying capacity, angular movement and reliable performance in articulated mechanical connections.
Also known as GE…LO in certain product designation systems, GEEW…ES belongs to the W dimensional series of radial spherical plain bearings. It features a steel-on-steel sliding contact design and is suitable for applications involving oscillating movement and angular misalignment.
The inner ring has a convex spherical sliding surface that moves against the matching concave surface of the outer ring. This construction allows the bearing to accommodate angular movement between connected components while transmitting radial loads.
GEEW…ES bearings are particularly suitable for standard hydraulic cylinder mounting arrangements, including cylinder base connections and piston rod connections.
Steel-on-steel sliding contact: Designed to support demanding loads in industrial articulated joints.
Angular movement: The spherical sliding design accommodates angular misalignment between connected components.
Relubrication capability: Lubrication grooves and holes facilitate grease replenishment and routine maintenance.
MoS₂ surface treatment: Molybdenum disulfide treatment on the sliding surfaces supports sliding performance and wear resistance.
Robust bearing construction: Hardened bearing steel rings provide a durable structure for demanding operating conditions.
Standardized dimensions: The W dimensional series is associated with DIN ISO 12240-1, making dimensional compatibility an important consideration when selecting replacement bearings.
One of the main applications of GEEW…ES spherical plain bearings is in standard hydraulic cylinders. They can be used at cylinder base mounting points and piston rod connections where the joint must transmit force while allowing pivoting movement.
These bearings are suitable for relevant mounting arrangements associated with DIN 24333 and DIN 24336. The exact bearing size and mounting configuration should be verified against the cylinder design.
Construction and earthmoving equipment often contains articulated connections exposed to heavy loads, vibration and repeated movement. GEEW…ES bearings may be used in suitable pivot joints and linkage mechanisms where their load ratings and movement characteristics meet the application requirements.
Agricultural equipment uses articulated linkages and pivot points to connect moving components. GEEW…ES bearings can be considered for applications requiring load transmission, angular movement and regular relubrication.
In industrial equipment, GEEW…ES bearings can support pivoting connections and articulated mechanisms where alignment variations occur during operation. They are suitable for applications in which a steel-on-steel sliding bearing and a planned lubrication schedule meet the operating requirements.
The main difference is the dimensional series and bearing configuration. GEEW…ES belongs to the W dimensional series and has an extended inner-ring design compared with the standard E-series configuration. This makes it suitable for particular hydraulic cylinder mounting arrangements.
When replacing a GE…LO bearing with a GEEW…ES bearing, or comparing it with a GE…ES model, always check the bore diameter, outside diameter, inner-ring width, outer-ring width, load ratings and permissible angular movement. Similar product designations do not automatically guarantee that all dimensions or performance ratings are interchangeable.
GEEW…ES bearings are maintenance-required bearings. Regular relubrication is important for maintaining suitable sliding conditions and supporting service life.
The lubrication interval and grease selection should be determined according to the operating load, movement, temperature, environment and manufacturer's recommendations. Applications with difficult maintenance access should be assessed carefully before selecting a maintenance-required bearing.
SPB Bearings supplies spherical plain bearings and related products for hydraulic equipment, industrial machinery and other articulated applications.
We understand that selecting the correct bearing involves more than matching the bore diameter. Dimensional compatibility, load requirements, angular movement, lubrication and installation conditions all need to be considered.
