Features & Benefits


• Both sides sealed to enhance durability and protect against contamination

• Steel construction ensures robust performance under high load conditions

• Rated static load of 6.55kN supports heavy machinery requirements

• High dynamic load capacity of 13.5kN for reliable rotation

• Designed with CN clearance for optimal performance in various axial and radial loads

• Compact deep groove design suitable for limited space requirements

Applications


• Used for Precision machinery fittings in automation equipment

• Suitable for Electrical motor assemblies where high-speed operation is required

• Ideal for mechanical devices requiring long-lasting performance

• Recommended for industrial ball bearings in manufacturing environments

How does the sealing arrangement impact performance?


The seals on both sides prevent dirt and moisture ingress, significantly enhancing the bearing's lifespan and operational reliability even in harsh environments.

What are the implications of the dynamic load rating in practical use?


The dynamic load rating of 13.5kN allows the bearing to efficiently handle substantial ongoing loads during operation, making it ideal for machinery that operates under heavy stress.

Can this bearing be used in high-temperature environments?


The steel material can withstand moderate temperatures, but for extreme conditions, it is advisable to evaluate the lubrication method and operating limits.

What clearance do I need for optimal usage?


The CN clearance offered is suitable for general applications, balancing the fit and function while accommodating regular movements between the shaft and housing.

Is replacement of this bearing straightforward?


Yes, the standard dimensions and design facilitate easy replacement with minimal adaptations necessary in existing setups.

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
