Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
Deep Groove Ball Bearings
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
