Bearings for extreme use
The TOPLINE bearing range integrates SNRs latest technological innovations and provide a suitable solution for the most extreme operating conditions.
The range breaks down into 4 families, the bearings can sustain temperatures from -60°C to +200°C and rotating speeds up to 700,000 N.Dm.
Technical data:
- Steel cages,
- Available in sealed (fluorinated elastomer or Viton seal, depending on the Series) or protected version (lower cost baffles suitable for high rotating speeds).
- Greases selected for their excellent performance in application, and submitted to thorough testing. Grease is accountable for 70% of bearing failures. Therefore, the utmost care exercised in greases selection now contributes to bearing quality, while guaranteeing reliability and extending service life.
Applications examples: Electrical motors, alternators, industrial ventilation, compressors, heating pumps, driers, frigorific facilities, photocopiers, couplers, textile machines, ski lift/ chairlift compressors
Series:
FT150 - FT 150 ZZ (T° up to 150°C) 6000 FT, 6200 FT, 6300 FT
HT200 - HT200 ZZ (T° up to 200°C) 6200 HT, 6300 HT
HV ZZ (Speed up to 700,000 N.Dm) 6000 HV, 6200 HV
LT - LT ZZ (T° up to -60°C) 6000 LT, 6200 LT

F600: A technical bearing range for slow motion handling at high temperatures
Fitted with a steel sheet cage, the F600 range bearings receive a specific surface treatment making them more resistant to oxidation and thermal shocks, and allowing operations between 200°C and 350°C.
Suitable for slow handling at high temperatures, they require a rotating speed of less than 50 RPM and moderate loads. Radial clearance was increased to compensate for thermal expansion deviations between the 2 rings and for neighbouring component distortions.
The F600 series also includes:
- F604 bearings, suitable for high pollution environments, with a high temperature lubricant and protected by two integral baffles,
- F605 bearings, for limestone baking oven, of open design, stabilised up to 350°C temperature, without surface treatment.
The special treatments of the F600 series can be applied on request to other bearing symbols and types (e.g. spherical roller bearings). Please contact SNR`s technical departments.
Applications examples: oven carriages, transport rolls, conveyors, porcelain works, glass making, foundries, cement plants, brick plants…
Series: F600 (standard), F604 (greased and protected), F605 (limestone process)
6000, 6200, 6300
