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
