FR 166 ZZ
Deep groove ball bearings
FR 166 ZZ
Deep groove ball bearings
Bearing with double-sided metal seal (ZZ). The seal helps protect the bearing from dust, dirt and other external contaminants while allowing low-friction rotation.
- Product description
- Technical details
- FAQ
A concentrated protective fluid intended for the preparation of coolant by mixing with water. The level of freeze protection is adjusted according to the selected mixing ratio (see table below). It is compatible with water in all proportions and with conventional coolants of the same chemical base.
Features and Benefits
- High chemical stability
- Long service life in cooling systems
- Reliable protection of metal components against corrosion and rust
- Efficient heat transfer and protection against overheating
- Neutral behavior toward rubber and plastic materials
- Low foaming tendency
- Free from silicates, nitrites, amines, and phosphates
- No deposit formation in the cooling system
Applications
- Cooling systems of modern gasoline engines
- Passenger cars
- Commercial vehicles
- Construction and agricultural machinery
Mixing Ratios
| Ratio (concentrate / water) | Protection down to |
|---|---|
| 40 % / 60 % | −20 °C |
| 45 % / 55 % | −25 °C |
| 50 % / 50 % | −35 °C |
| 55 % / 45 % | −40 °C |
Note: At concentrations below 33%, corrosion protection is insufficient.
The product is not suitable for use in an undiluted state.
Specifications and approvals
- BS 6580 – 1992/2010
- NF R15-601
- H373: May cause damage to organs
through prolonged or repeated exposure .
