Description
HD Crankshaft Bearings and FKM Oil Seals
HD (for Heavy Duty) crankshaft bearing set incl. FKM oil seals from Naraku. The bearing set contains 2x crankshaft bearings with polyamide cage and the matching crankshaft seals.
Heavy duty bearings are especially durable and long lasting. Only high quality SKF bearings with C4 bearing clearance are used. Ideal for street use or racing. The polymer plastic cage has higher elasticity and reduces friction, so the bearings run cooler and lighter. The bearings should not be permanently exposed to temperatures above 120°C, so they should not be used in engines with catalytic converters.
The premium oil seals made of high-quality FKM (fluoro-rubber) provide a reliable and long-lasting seal. The material is resistant to all engine oils and fuels and has optimum thermal properties.
We recommend always using new bearings and sealing rings when replacing the crankshaft.
Suitable for:
- Kymco and SYM vertical such as Kymco Fever KCA 50, KB 50, DJ 50, Curio 50 CX and Fever ZXII 50
- Honda Dio 50, Meteorite KB50, SYM Flash / Fancy and Daelim S-Five
Crankshaft bearings for motorcycle, scooter and moped
Crankshaft bearings ensure the smooth operation of engines, whether on scooters, motorcycles or mopeds. The crankshaft is an integral part of the engine and the associated bearings and seals must be in perfect condition.
A crankshaft bearing set consists of ball bearings and oil seals. They are usually sold as a complete set and must be replaced each time the crankshaft is installed/re-installed.
What are the symptoms of defective crankshaft bearings?
The main symptoms of a defective crankshaft bearing are:
- Unusual metallic noises coming from the direction of the crankshaft.
- Unusual vibrations of the vehicle.
Defective bearings must be replaced immediately, otherwise there is risk of further damage to the engine. There are many different tools for crankshaft removal or bearing pullers.
You can see how to change crankshaft bearings in our crankshaft disassembly and assembly tutorial.
