SKF, a world leader in bearing technology, also manufactures and supplies angular contact ball bearings to meet requirements for pump manufacturers.
Pumps are used in a variety of industries where a high degree of reliability is required. In order to meet these severe operating conditions, SKF has created a new generation of contact angular ball bearings which increase pump service life with benefits such as increased safety factors, reduced vibration and heat generation and increased service intervals and machine uptime.
Bearings are exposed to high combined axial and radial loads, moderate to high speeds, and in some cases, high temperatures and SKF Explorer single row angular contact ball bearings comfortably meet the demands of pumps. Angular contact ball bearings are manufactured to P5 running accuracy and P6 dimensional accuracy to better meet the demands of pump OEMs.
Single row angular contact ball bearings are engineered for combined loads, high speeds, marginal lubrication and are resistant to conditions of mild contamination, while the double row angular contact ball bearings are specially designed for combined loads and high running accuracy. The single row angular contact ball bearings usually operate with small axial clearance or a light preload to accurately locate the shaft and eliminate the harmful effects of ball skidding.
SKF Explorer double row angular contact ball bearings are used extensively in medium duty pumps due to excellent load and speed capabilities as well ease of mounting. A bearing with a pressed steel cage is typically used for these applications. These bearings have a 30° contact angle to accommodate high thrust and shock loads encountered during cavitation.
These new generation single and double row angular contact ball bearings feature cleaner steel, less impurities and a unique heat treatment process to provide temperature stabilisation up to 150°C. The process provides more durable raceways that are less sensitive to spalling and contamination damage.
