61814 Single Row Ball Bearing

61814 Single Row Ball Bearing - Compact Precision Solution for Space-Critical Applications

When your design requires a large 70mm bore diameter but faces severe radial space constraints, the 61814 Single Row Ball Bearing delivers the perfect engineering solution. This thin-section deep groove ball bearing combines robust load capacity with an exceptionally compact 10mm width profile. You get the structural benefits of a large shaft diameter without compromising your equipment's space efficiency. The product addresses the critical design challenge where traditional bearing series would create unacceptable bulk in precision machinery applications.

Design Structure and Working Principle

The 61814 features a specialized thin-section architecture optimized for space-constrained applications. The bearing consists of precision-ground inner and outer rings with deep raceway grooves that accommodate steel balls in a point-contact configuration.

Key structural elements include:

• Optimized raceway curvature that distributes loads evenly across the contact points
• Precision steel balls manufactured to strict sphericity tolerances
• Stamped steel cage that maintains proper ball spacing and guidance
• Compact cross-section design achieving maximum bore-to-width ratio

The working principle relies on rolling contact between the balls and raceways. This configuration generates minimal friction while supporting both radial and moderate axial loads simultaneously. The deep groove geometry provides inherent axial location capability in both directions.

Performance Advantages

Space Optimization

The 10mm width conveys greatest compactness without relinquishing the 70mm bore prerequisite. You accomplish ideal space utilization in congregations where each millimeter matters.

Low Grinding Operation

Reduced rolling component measure and optimized contact geometry result in lower beginning torque and running grinding compared to standard arrangement orientation. This interprets to progressed vitality productivity and decreased warm generation.

Versatile Stack Handling

Despite its compact profile, the bearing handles noteworthy outspread loads and direct pushed loads in both bearings. The profound raceway plan gives steady pivotal positioning.

High-Speed Capability

Lightweight development and adjusted cage plan empower dependable operation at speeds up to 6,000 RPM with appropriate grease, making it appropriate for high-performance applications.

Manufacturing Precision

Manufactured to ISO 492 guidelines with discretionary accuracy grades accessible. Steady dimensional exactness guarantees solid fit and execution in basic applications.
