GQZ 7004-B-2RS Single Row Angular Contact Ball Bearing 20×42×12mm 40° Contact Angle Double Rubber Sealed

7004-B-2RS is standard single row angular contact ball bearing.

• B: 40° contact angle, superior axial load carrying capacity
• 2RS: Double-sided contact NBR rubber seals, effective against dust and water splash

  It bears combined radial load and one-way axial load. Single bearing can be arranged back-to-back, face-to-face or tandem paired to withstand bidirectional axial force. Sealed structure retains factory pre-filled grease for long maintenance-free operation. Suitable for medium-speed, dusty and humid working environments. Widely applied on hydraulic pumps, small spindles, packaging equipment, textile machinery and general automation rotary assemblies.

  Formal quotation will be sent within 24 hours upon your inquiry.
