GEBK...S

GEBK...S Spherical Sliding Bearing - High Load Capacity and Misalignment Tolerance

Product Features

• High Load Rating: Designed to support significant radial and axial loads, suitable for heavy-duty industrial applications.
• Self-Aligning Capability: The spherical inner ring can accommodate angular misalignment, reducing edge stresses and extending service life in non-ideal installations.
• Corrosion Resistance: Available with surface coatings to protect against environmental corrosion, suitable for use in damp or chemically exposed environments.
• Maintenance-Free Operation: The sliding surfaces are lubricated with PTFE composite, eliminating the need for regular re-lubrication in most operating conditions.

Product Description

The GEBK...S spherical sliding bearing is engineered to provide reliable performance in applications requiring high static and dynamic load support with the ability to accommodate angular misalignment. Manufactured to DIN ISO 12240-1 standards, this bearing features a steel-on-PTFE composite sliding contact surface. The steel outer ring is precision-machined, while the inner ring is chromium-plated and ground. This configuration ensures a low-friction sliding surface and a long service life, reducing operational maintenance costs for machinery manufacturers and equipment operators. The GEBK...S series is commonly specified in designs for construction machinery, hydraulic cylinders, and agricultural equipment.

Application Areas

This spherical sliding bearing is specified for various industrial applications where robust performance and tolerance to misalignment are critical. Common use cases include:

• Hydraulic cylinder linkages in construction and mining equipment.
• Pivot joints and articulations in heavy-duty agricultural machinery.
• Suspension systems and steering mechanisms in commercial vehicles.
• Industrial automation and robotics for precise movement under load.
• Structural components in civil engineering projects, such as bridges and dams.

FAQ - Frequently Asked Questions for GEBK...S Spherical Sliding Bearings

1. What is the difference between a GEBK...S and a standard GE...DO bearing, and how do I choose the right one for a specific application?

The primary difference lies in the lubrication and maintenance requirements. A standard GE...DO steel-on-steel spherical plain bearing requires regular re-lubrication, making it suitable for applications with high loads and a defined maintenance schedule. In contrast, the GEBK...S steel-on-PTFE composite bearing is designed for maintenance-free operation. This makes it a more suitable choice for applications where access for re-lubrication is difficult or impossible, or where maintenance costs need to be minimized. The selection between the two depends on your specific operational conditions, including load type, speed, environmental factors, and maintenance strategy. We recommend a detailed review of your specific bearing requirements with our technical sales team for optimal product selection.

2. How does the GEBK...S bearing's misalignment tolerance affect its service life, and what is its operational temperature range?

The self-aligning capability of the GEBK...S series helps prevent premature failure by accommodating angular misalignment that can arise from housing bore inaccuracies or shaft deflection. This capability ensures that the load is distributed evenly across the sliding surfaces, which in turn reduces localized stress and extends the bearing's service life. The operational temperature range for this bearing is typically from -50°C to +150°C. However, the exact performance, particularly regarding static load capacity, can be influenced by temperature extremes. For applications operating at the upper or lower limits of this range, or in fluctuating temperature environments, it is essential to consult the detailed technical data sheets.
