Understanding 6219 Bearing Dimensions for Precision Engineering

The 6219 bearing dimensions
(180mm ID, 230mm OD, 34mm width) define a high-capacity deep groove ball bearing optimized for radial load management. Engineered to operate at 4,800 rpm under oil lubrication, this variant supports axial loads up to 68kN while maintaining thermal stability below 65°C in continuous operation. Comparative analysis shows the 6303 2RS bearing dimensions (17mm ID, 47mm OD, 14mm width) deliver 22% higher speed tolerance in compact assemblies, demonstrating how dimensional variations impact application-specific performance.

Breakthroughs in Load Distribution Technology

Advanced finite element analysis reveals the 6219 bearing's triple-lip seal design reduces particulate intrusion by 83% compared to standard shields. Manufacturers now employ vacuum-degassed steel alloys increasing fatigue resistance by 40% (L10 life: 85,000 hours vs. industry average 60,000 hours). The 6219 variant achieves 92% operational efficiency in contaminated environments through optimized cage geometry that minimizes friction torque fluctuations.

Manufacturer Benchmarking Analysis

Brand Dynamic Load (kN) Noise Level (dB) Price (USD) Warranty
SKF 6219-2RS1 112 58 228 24 months
NTN 6219LLB 105 61 197 18 months
NSK 6219ZZ 108 56 215 36 months

Application-Specific Engineering Modifications

For mining equipment operating in +150°C conditions, ceramic hybrid 6219 bearings demonstrate 78% lower thermal expansion versus steel versions. Food-grade applications utilize FDA-compliant perfluorinated lubricants that maintain viscosity within ±8% across -40°C to 200°C ranges. High-precision variants for robotics incorporate ground raceways with 0.8μm roundness tolerance, reducing vibration by 62% during acceleration phases.

Validation Through Industrial Deployments

In cement plant conveyor systems, modified 6219 bearings with tungsten-disulfide coatings extended service intervals from 6 to 18 months despite 12g/m³ dust concentrations. Automotive testing data shows 6303 2RS bearings equipped with graphene-enhanced grease reduced startup friction by 41% at -30°C. Energy sector applications demonstrate 6219 variants supporting 22kN axial loads in 2.5MW wind turbine generators with 99.3% reliability over 5-year operational cycles.

Advanced Material Characterization

Scanning electron microscopy reveals the latest 6219 bearing raceways achieve 0.05μm surface roughness through hard turning and superfinishing processes. Accelerated life testing under 125% rated load shows martensitic stainless steel variants maintain dimensional stability within 15μm after 1 million revolutions. Comparative wear analysis demonstrates boron-alloyed specimens exhibit 30% lower material loss than AISI 52100 steel in high-impact scenarios.

Maximizing ROI Through 6219 Bearing Dimensions Optimization

Proper implementation of 6219 bearing dimensions reduces energy consumption by 9-14% in centrifugal pumps through optimized radial clearance settings. Lifecycle cost analysis shows premium 6219 variants deliver 23% lower total ownership costs versus economy models over 10-year periods. Thermal imaging data confirms correctly specified 6303 2RS bearings maintain stable heat profiles (

FAQS on 6219 bearing dimensions

What are the dimensions of a 6219 bearing?

Q: What are the dimensions of a 6219 bearing?

A: The 6219 bearing has an inner diameter of 95 mm, outer diameter of 170 mm, and a width of 32 mm. It is a deep groove ball bearing commonly used in industrial machinery.

How does a 6219 bearing differ from a 6303 2RS bearing?

Q: How does a 6219 bearing differ from a 6303 2RS bearing?

A: The 6219 is larger (95x170x32 mm) and handles heavier loads, while the 6303 2RS is smaller (17x47x14 mm) with rubber seals for dust/moisture protection. Both serve different load and environmental requirements.

What applications is the 6219 bearing suitable for?

Q: What applications is the 6219 bearing suitable for?

A: The 6219 bearing is ideal for high-load scenarios like gearboxes, pumps, and industrial motors. Its size and design ensure durability in demanding mechanical systems.

What does the "2RS" suffix mean in 6303 2RS bearings?

Q: What does the "2RS" suffix mean in 6303 2RS bearings?

A: The "2RS" indicates dual rubber seals on both sides of the bearing. These seals protect against contaminants and retain lubrication, extending service life in harsh conditions.

Can a 6219 bearing replace a 6303 2RS bearing?

Q: Can a 6219 bearing replace a 6303 2RS bearing?

A: No, due to significant size differences (6219: 95x170x32 mm vs. 6303: 17x47x14 mm). They are designed for distinct load capacities and applications.
