7000 Angular Contact Ball Bearing | Single Row High Precision Axial And Radial Bearings
The 7000 series angular contact ball bearing is a high-precision single-row rolling bearing designed to bear combined radial and unidirectional axial loads. Different from self-aligning bearings, it features a unique contact angle structure that enables simultaneous dual-load bearing capacity, delivering high rigidity, low friction and high-speed stability. Widely configurable with multiple sealing types and industrial materials, the 7000 bearing is a core precision component for high-speed, low-vibration and high-precision industrial transmission equipment.
7000 Bearing Sealing Types And Functional Advantages
7000 series angular contact bearings support multiple mainstream sealing structures to adapt to different working environments, effectively preventing grease leakage and external impurity invasion:
Open Type: No sealing cover on both sides, featuring minimal rolling resistance and excellent heat dissipation. It supports frequent lubrication replacement, suitable for clean indoor environments, low-dust workshops and equipment with independent oil supply systems, ideal for ultra-high-speed precision operation.
Z / ZZ Metal Shield Seal: Equipped with single-sided or double-sided thin metal dust covers. It blocks large particles and dust with low friction loss, retaining high-speed performance. Perfect for dry, low-dust industrial scenarios and general high-speed mechanical equipment.
RS / 2RS Rubber Contact Seal: Single or double-sided rubber contact sealing structure with tight fitting. It effectively isolates moisture, fine dust, oil dirt and corrosive particles, realizing full internal grease sealing. Suitable for humid, dusty and complex workshop environments with no frequent lubrication conditions.
