What Are 718 Series Angular Contact Ball Bearings?

The 718 Arrangement speaks to ultra-thin area precise contact ball orientation outlined to oblige combined spiral and pivotal loads in greatly compelled spaces. Classified beneath ISO measurement arrangement 18, these orientation highlight negligible cross-sectional tallness compared to standard bearing series.

You'll appreciate how these heading fathom basic industry torment focuses related to space-weight-rigidity trade-offs. The plan permits for bigger shaft distances across without expanding lodging estimate, successfully expanding your system's in general solidness whereas lessening pivoting mass.

Key Design Features

The orientation utilize high-purity vacuum-degassed bearing steel (GCr15/52100) with precision-ground raceways. The lean cross-section encourages fast warm scattering, pivotal for keeping up steady preload amid nonstop high-speed operation.

Core structural advantages include:

  • Optimized ball-to-raceway contact geometry
  • Precision-machined cage designs (Bakelite or Nylon)
  • Multiple contact angle options for load optimization
  • Universal matching capabilities for simplified installation

Performance Advantages

Ultra-High Speed Capability

The diminished cross-sectional measurements and optimized ball breadths empower breakthrough execution at extraordinary speeds. Lighter rolling components create less centrifugal drive, permitting your gear to keep up exactness and steadiness at higher RPMs than customary bearings.

Superior Stiffness-to-Space Ratio

When mounted in back-to-back (DB) or face-to-face (DF) setups, these heading give extraordinary minute unbending nature. You'll accomplish higher basic firmness without expanding your equipment's physical envelope.

Enhanced Warm Management

The lean segment plan advances fast warm scattering, avoiding warm development that may compromise preload settings. This warm solidness guarantees reliable execution amid expanded high-speed operation.

Precision Manufacturing

Manufactured to P4 or P2 resistance guidelines, these orientation convey running exactness with runout regularly underneath 2.5 microns. This exactness level bolsters your most requesting situating and movement control applications.

Industrial Applications

CNC Machine Tool Spindles

In precision machining centers, you'll find these bearings supporting grinding and milling spindles where high RPMs must coexist with exceptional radial stiffness. They prevent tool chatter while maintaining the precision required for superior surface finishes.

Industrial Robotics

For robotic arm joints and harmonic drive reducers, space constraints demand compact solutions. The 718 Series Angular Contact Ball Bearings withstand high tilting moments and complex loads from rapid acceleration and deceleration cycles.

Semiconductor Manufacturing Equipment

In wafer inspection stations and photolithography equipment, these bearings support precision positioning tables requiring nanometer-level accuracy in vacuum environments. Special vacuum-compatible configurations ensure reliable performance in these critical applications.

Medical Device Spindles

High-speed dental handpieces and surgical tools benefit from the low noise characteristics and smooth operation these bearings provide, often achieving noise levels below 35dB.

Contact Angle Selection Guide

15° Contact Angle (Type C)

Optimized for applications with primarily radial loads and maximum speed requirements. The reduced contact angle minimizes friction losses, making it ideal for ultra-high-speed spindles.

25° Contact Angle (Type AC)

Provides superior axial load capacity and increased stiffness. Choose this configuration when your application involves significant thrust loads or requires maximum moment rigidity.

40° Contact Angle

Best suited for applications with heavy axial loads while maintaining moderate speed capabilities.

Installation and Configuration Options

Universal Matching (SU)

Our precision grinding process ensures any two bearings can be mounted together in any arrangement without shims, automatically achieving preset preload. This feature simplifies your inventory management and assembly procedures.

Mounting Arrangements

  • DB (Back-to-Back): Maximum moment stiffness
  • DF (Face-to-Face): Optimal for applications with external moment loads
  • DT (Tandem): Increased axial load capacity
