SKF VA series deep groove ball bearings are single row bearings with stainless steel cage and metal shields, designed to withstand elevated temperatures. They are used in applications where heat is constant, such as ovens, industrial fans and process equipment. MR Accesorios Industriales sells this line, backed in the industry.
The designation of these bearings combines the basic size with suffixes that indicate special characteristics. For example, in 6003-2Z/VA201, the 6003 corresponds to the size of the 60 series, the suffix 2Z indicates two metal shields (one on each side) and VA201 is the SKF code for an execution suitable for high temperatures. The suffix VA208 identifies another thermal variant within the same category. Knowing these codes allows you to choose the right bearing according to the working temperature and the type of sealing.
These bearings are used in industries where heat is a critical factor: industrial ovens, dryers, induced draft fans, clinker conveyors and process equipment in chemical or food plants. In Argentina, they are commonly found in the cement, ceramics, glass and metal heat treatment industries. Their construction with stainless steel cage and metal shields makes them suitable for environments with elevated temperatures and the presence of dust or vapors.
To select the right bearing, take into account the maximum operating temperature, the type of load (radial, axial or combined) and environmental conditions. The VA series is intended for high temperatures, but it is essential to verify that the lubricant and seals withstand that regime. During mounting, ensure correct alignment between shaft and housing, and avoid impacts that could damage the seals. Proper lubrication and internal clearance also influence performance and service life.
When replacing a bearing, it is common to look for equivalents between brands. Although each manufacturer has its own codes, deep groove ball bearings with suffixes indicating sealing and high temperature usually have equivalents in other brands. The important thing is to compare the main dimensions (bore, outer diameter and width) and the service conditions.
