Technical Abbreviation: MR74

RCS Ball Bearings with metal shielding

are made from hardened stainless steel AISI 440 C .
tolerance class is ABEC-3 (P6, class 6)
the bearings meet the ISO 9001 and ROHS standards
they are already high quality lubricated, oil has anti-rust and noise suppresive properties
temperature range of -50°C to 150°C, low-noise and friction also at high speeds

Ball Bearings with metal shielding have a lower roll resistance, give more speed and battery duration.

Heat is better dissipated, therefore these bearings are more wear resistant especially at higher RPM.

On the other hand the metal seal does not protect as good as rubber sealed bearings against dust and dirt.

Ball bearings with metal shield are therefore most suitable for parts like motor, gearbox , clutch etc. and also for the suspension of cars that are not driven in the dirt.
