Inch-size steel-on-steel spherical plain bearing with 2RS double-side seals
SPB GEWZ…ES-2RS radial spherical plain bearings are designed for heavy-duty applications requiring high load-carrying capacity, angular movement and additional protection against dust and external contaminants.
The GEWZ…ES-2RS series features inch-based dimensions and a steel-on-steel sliding contact design. Compared with the open GEWZ…ES version, GEWZ…ES-2RS is equipped with two seals, one on each side of the bearing.
These seals help prevent dust, dirt and other external contaminants from entering the sliding contact area, helping keep the bearing surfaces cleaner and reducing the risk of contamination-related wear.
Inch-based dimensions: Suitable for equipment designed around imperial measurements.
Double-sided seals: Two seals help protect the sliding contact surfaces against dust and external contaminants.
Steel-on-steel sliding surfaces: Designed for heavy-duty applications involving substantial loads.
Angular movement capability: Accommodates oscillating and angular movement within the specified limits.
Additional contamination protection: Particularly useful where dust and dirt may reach the bearing during operation.
GEWZ…ES-2RS bearings can be considered for heavy-duty articulated connections where additional contamination protection is desirable, including:
Construction machinery: Pivot joints and linkage mechanisms exposed to dust and dirt.
Agricultural machinery: Articulated connections operating in outdoor or dusty environments.
Hydraulic equipment: Selected mounting and linkage arrangements requiring inch-based dimensions.
Industrial machinery: Heavy-duty joints where protection against external contaminants is important.
Bearing selection should take into account the actual loads, movement, operating temperature, lubrication arrangement and environmental conditions.
The main difference is the sealing arrangement.
GEWZ…ES: Open bearing design without additional side seals.
GEWZ…ES-2RS: Two additional seals, one on each side, to help prevent dust and external contaminants from entering the bearing.
The sealed version offers additional protection in contaminated environments. However, the seals should not be interpreted as a guarantee of complete waterproofing or a fully sealed system.
GEWZ…ES-2RS bearings require maintenance according to their specific design and operating conditions. The seals help protect the sliding area from external contaminants, but they do not necessarily eliminate the need for lubrication.
The referenced product specifications state a permissible operating temperature range of −30°C to +130°C. Please confirm the applicable limits against the relevant SPB product specification.
SPB Bearings offers spherical plain bearing solutions for industrial machinery and demanding articulated applications. GEWZ…ES-2RS combines inch-based dimensions, a steel-on-steel sliding structure and double-sided seals to help protect against dust and external contamination.
