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
