SKF 6304NR Single Row Deep Groove Ball Bearing- Open Type 20mm I.D, 52mm O.D / 1262543

SKF High Temperature Deep Groove Ball Bearing. SKF Ball Bearings are designed to deliver increased reliability, reduced complexity and decreased environmental impact in high operating temperatures. Features: Excellent performance in hot conditions, dry environments and low rotational speed applications Temperature range -30°C to 150°C Suitable for high and very high speeds Steel/Ceramic ball material Plain race type Low friction Available in many designs, variants and sizes Why choose Deep Groove Ball Bearings? For their versatility - channelling radial and axial loads they are widely used in many industries Cost efficient - due to low friction torque the temperature remains low therefore reduces the energy cost of running in equipment such as the conveyor belt Low maintenance - no additional lubrication after installation Applications: Agricultural industry Food processing Machine Tools Material handling Medical/Pharmaceutical Printing Wind energy What is the inner ring diameter? A range between 6 mm to 40 mm What is internal/external design? 2RS1 - Contact seal NBR on both sides 2RSH - Contact seal NBR on both sides Z, 2Z - Shield on one or both sides 2RSL - RSL low-friction contact seal on both sides of the bearing 2RZ - RZ low-friction non-contact seal on both sides of the bearing 2ZNR - Shield on both sides, snap ring groove in the outer ring, with snap ring NR - Snap ring groove in the outer ring, with an appropriate snap ring E - Reinforced ball set Cage Design TN9 - Glass fibre reinforced polyamide 66 cages, rolling element centred Stainless steel Lubrication GJN - Grease with a polyurea thickener of consistency 2 to the NLGI scale for a temperature range -30°C to +150°C (normal fill grade) VT162 - Lubricated with Klueber Isoflex Topas NB52 grease WT - Grease with a polyurea thickener of consistency 2 to 3 to the NLGI Scale for a temperature range –40°C to +160 °C LHT - Grease with a lithium thickener of consistency 2 to 3 to the NLGI Scale for a temperature range –50°C to +140 °C HT - Grease with a polyurea thickener of consistency 2 to 3 to the NLGI Scale for a temperature range –40°C to +150 °C (normal fill grade) Accuracy/Clearance C2 - Radial internal clearance smaller than normal C3 - Internal clearance greater than normal C4 - Radial internal clearance greater than C3 C5 - Radial internal clearance greater than C4
