High Light Hybrid Ceramic Angular Contact Ball BearingSingle Row Angular Contact Bearing 20×47×14mmAngular Contact Ball Bearing 15° Contact Angle
1. Product Overview

S7204CD/HC is super precision single row angular contact ball bearing.

  • S: Universal matchable design
  • CD: 15° contact angle, high-capacity D internal geometry
  • HC: Hybrid construction, steel inner & outer rings + silicon nitride ceramic rolling elements with electric insulation capability

Open structure supports circulating oil lubriion. It bears combined radial load and one-way axial load. Single bearing can be arranged back-to-back (DB), face-to-face (DF) or tandem (DT) to withstand bidirectional axial loads. Ceramic balls reduce centrifugal force at high rotation speed, restrain electric erosion and lower operating temperature. Widely adopted on high-speed CNC spindles, frequency conversion servo motors, ball screw supports and high-precision rotary equipment vulnerable to stray current damage.

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

3. Core Advantages
  1. HC hybrid ceramic rolling elements achieve insulation performance, effectively avoid bearing electric pitting corrosion
  2. 15° CD high-capacity structure balances high-speed performance and load carrying capacity
  3. S universal matchable design, flexible for various duplex paired installation modes on site
  4. Low-density ceramic balls cut centrifugal load, realize higher limiting speed than all-steel bearings
  5. Open design adapts continuous circulating oil lubriion for long-term high-speed precision operation
  6. Customizable: P4/P5 precision grade, multiple preload classes, OEM laser marking, dedied high-speed grease
4. Appliion Scenarios
  • High-speed vertical & horizontal machining center main spindles
  • Variable frequency servo motors and generator rotary shafts
  • Precision ball screw fixed-end support assemblies
  • High-speed grinding machinery and automation precision transmission units
  • Rotary equipment exposed to stray electric current and electric corrosion risk
