Answer ‘DDU’ indicates that the bearing is equipped with contact rubber seals on both sides, offering excellent protection against contamination. ‘CM’ specifies a special radial internal clearance designed for electric motors, ensuring quieter operation. ‘NS7S’ refers to a specific type and fill of high-performance grease, also suited for motor applications. Question? Can I use this bearing in a high-speed application? Answer While the 6302 bearing is versatile, the ‘DDU’ contact seals introduce more friction than open or shielded bearings. This makes it ideal for moderate speeds where contamination is a concern. For very high-speed applications, an open (no suffix) or shielded (ZZ) version with a different clearance (like C3) might be more appropriate. Always consult the manufacturer’s speed rating for your specific load conditions. Question? Is this bearing interchangeable with an SKF 6302-2RSH or a FAG 6302-2RSR? Answer Yes, dimensionally it is a direct interchange. The basic dimensions (15mm bore, 42mm outer diameter, 13mm width) are standardized. The suffixes indicate similar features: ‘2RSH’ from SKF and ‘2RSR’ from FAG also denote contact seals on both sides. While grease and internal clearance specifications might have minor differences, for most general applications, they are considered functional equivalents. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
