This shielded deep groove ball bearing belongs to the 6210 series and is offered in multiple shielded variants: 6210, 6210Z, 6210ZZ, and 62102Z. It is a single row bearing with a bore of 50 mm, outer diameter of 90 mm, and width of 20 mm, sold as 1 piece. Key benefits Shielded design options (Z, ZZ, or 62102Z) provide protection against dust and help retain lubricant, improving durability in challenging environments. Deep groove geometry delivers smooth operation, low friction, and reliable performance under typical radial loads with moderate axial load capability. Single row configuration offers a compact, costeffective solution for many applications requiring standard 50x90x20 mm dimensions. Widely compatible with standard housings and shafts that accept a 50 mm bore. Key attributes Model family: 6210 series; variants include 6210, 6210Z, 6210ZZ, 62102Z Dimensions: bore 50 mm, outer diameter 90 mm, width 20 mm Bearing type: deep groove ball bearing, single row Shielding options: Z (single shield), ZZ (double shield); 62102Z indicates double shielding in the variant naming Quantity per unit: 1 piece Use cases Replacement bearing in a conveyor roller, idler, or similar support where space is limited and shielding is beneficial to keep contaminants out. Drive pulley, fan, or small motor assembly requiring reliable radial support with protective shielding. Agricultural equipment, workshop machinery, or lightindustrial pivots and linkages that require a compact, shielded 50x90x20 mm bearing. Notes Confirm fit by matching bore (50 mm), outer diameter (90 mm), and width (20 mm) to the housing and shaft. The listing covers multiple shielded variants; choose 6210, 6210Z, 6210ZZ, or 62102Z according to the desired level of sealing.
