Deep groove ball bearings are suitable for high speeds. KBC deep groove ball bearings are heat-treated in such a way that they can be used at operating temperatures of up to 120 degrees. KBC supplies deep groove ball bearings with shields(Non-contact steel plate seals) or seals(Contact seals) on both sides. All these bearings are filled at the manufacturer's plant with a high-quality grease, tested to KBC specifications. Sealed bearings get to be sealed completely by labyrinth formed between seal groove on inner ring and shield bore. Sealed bearings are divided into two types depending on existence of contact between seal lip and bearing inner ring, namely contact and non-contact types. Non-contact seals, which create small and long labyrinth, have better sealing quality than shield type, although they produce about same torque performances. Contact seals are excellent sealers, but their torque and permissible speeds are inferior than those of shield or non-contact types.
