ISOFLEX TOPAS NB 52 1 kg synthetic rolling and plain bearing grease, wide temperature range and excellent water resistance
Description
ISOFLEX TOPAS NB 52 1 kg is a high-quality synthetic grease for rolling and plain bearings, based on synthetic hydrocarbon oil and a barium complex soap. The special thickener provides excellent load-carrying capacity, very good resistance to water and process media and reliable protection against corrosion, oxidation and ageing.
Its wide service temperature range from -50 to 120 °C (with short peaks up to approx. 150 °C) makes ISOFLEX TOPAS NB 52 suitable for both precision mechanisms and heavily loaded bearing arrangements in automotive and general industry.
Advantages and unique features
- Synthetic long-term grease for rolling and plain bearings in a wide temperature range.
- Good load-carrying capacity due to the special barium soap thickener.
- High resistance to water and process media – stable lubricating film even in humid environments.
- Very good corrosion protection and excellent resistance to oxidation and ageing.
- Suitable for low-temperature operation – remains soft and lubricating down to approx. -50 °C.
- Can be used on electrical contacts and components, reducing electrical resistance at the lubrication point when properly applied.
- Good compatibility with many plastics and elastomers (material compatibility tests recommended before series use).
- Proven performance in many years of use in the automotive and machine-building industries.
Properties and applications
- Bearing grease: for high-speed and highly loaded rolling and plain bearings in motors, fans, pumps, precision gearboxes and electromechanical actuators.
- Low-temperature service: maintains lubricating properties from approx. -50 °C, ideal for outdoor equipment, refrigeration systems and other low-temperature applications.
- Electrical components: suitable for contacts and electrical parts where it can reduce electrical resistance at the friction point.
- Tooth flank lubrication: can be used for tooth flanks in precision gears, e.g. in actuators, positioning drives and control mechanisms.
- Resistance to media and water: stable lubricating film in the presence of water, aqueous emulsions and typical process media.
- Automotive and industrial use: for wheel bearings, seat adjustment mechanisms, auxiliary drives and many other applications requiring reliable long-term lubrication.

Storage recommendations
Store ISOFLEX TOPAS NB 52 in its original, tightly closed cans in dry and clean rooms, away from heat sources and direct sunlight. Avoid extreme temperatures; room temperature is recommended. Do not store together with foodstuffs or strong oxidising agents. After opening, protect the grease from contamination (dust, metal particles) and always use clean tools for dispensing. Dispose of used grease and empty containers according to local regulations and do not release the product into drains or the environment.
FAQ
1) What are the main applications of ISOFLEX TOPAS NB 52?
It is primarily used for high-speed and heavily loaded rolling and plain bearings as well as precision gear drives and actuators operating over a wide temperature range.
2) Is ISOFLEX TOPAS NB 52 suitable for low-temperature applications?
Yes, it provides reliable lubrication from approx. -50 °C, making it suitable for outdoor equipment, refrigeration systems and other low-temperature environments.
3) Can this grease be used in combination with plastics?
The product is resistant to many plastics and elastomers, but due to the wide variety of materials, compatibility tests should be carried out before series application.
4) How often should the grease be replenished?
ISOFLEX TOPAS NB 52 is a long-term grease; relubrication intervals depend on load, speed and operating conditions. In practice it allows longer relubrication intervals compared to conventional lithium greases, reducing maintenance costs.
5) What is the correct way to apply ISOFLEX TOPAS NB 52?
Apply the grease with a brush, spatula, grease gun or cartridge, ensuring the lubrication point is clean and properly filled. Avoid overfilling bearings and keep dirt and moisture away from the lubrication area.
