6004-2RS (ID=20mm, OD=42mm, Thickness=12mm) 6004 2RS bearings are shielded on both sides to keep lubricant in Made of carbon steel carbon, durability and resistance to deformation under heavy loads ABEC 1 (P0) tolerance, Z2 noise level for most general use Static load of 5050 newtons and load dynamic 9400 newtons Product Normal precision single row, pre-lubricated. The ball bearings with deep groove are one of the most widely used bearings. They are used to support radial and axial loads in both directions. With low friction and high speed, ball bearings are cost effective and low maintenance. Carbon steel bearings are better in toughness than chrome steel bearings after quenching. These economical bearings are widely used in areas with low Mohs hardness requirement. Suitable for all kinds of industrial equipment, micro-s, small rotary s, office equipment, etc. Selection Guide: Shields (Z/ZZ Designation Suffix) - High Speed. Protect from dirt and debris. Sealed (Designation Suffix RS/2RS) - Manufactured from sheet steel reinforced nitrile butadiene rubber (resistant to oil and liquids). Lower limit speed than shield bearings. Specifications: Model: 6004-2RS Seal Type: Double Shield Inner/Outer Race Material: Carbon Steel Cage Material: Stamped Steel Inner Diameter (d): 20mm Outer Diameter ( D): 42mm Thickness (B): 12mm Dynamic load capacity (Cr): 9400N Static load capacity (Cor): 5050N Accuracy class: P0 (ABEC-1) Noise level: Z2 Number of packages: 4 pieces
