Single row deep groove ball bearings for electric lawn mowers
The typical design of an electric lawn mower has an armature shaft (vertical axis electric motor) on which the cutting blade is mounted through a safety clutch device.
The bearing characteristics include:
- Contacting rubber seals on both sides to prevent ingress of dust/grass and grease leakage
- Cages made of pressed steel or plastic (glass fiber reinforced polyamide)
- The use of grease with an operating temperature range of -30 to +130 °C
an internal radial clearance dependant upon the fitting tolerances - normally ISO CN or C3.
