Bearing RU8509TM, Single row Cylindrical Roller Bearings 44.45X85X28.575mm

32207 bearings are high-quality and precision-engineered components designed to meet the demanding requirements of a variety of industrial applications.

Design:
The RU8509TM incorporates advanced engineering principles to achieve optimal performance:
Precision Geometry: Features a line contact design between rollers and raceways, distributing loads evenly across the bearing surfaces for maximum efficiency2
Separable Construction: The inner and outer rings can be mounted independently, simplifying installation and maintenance procedures2
Optimized Roller Profile: Specially contoured rollers minimize edge stresses and prevent stress concentration, enhancing bearing life2
Versatile Configuration: Available in NU design (outer ring with two fixed ribs, inner ring without ribs) for axial displacement capability2
Material Selection: Manufactured from high-grade bearing steel with precise heat treatment for superior hardness and fatigue resistance

Seals:
The RU8509TM offers flexible sealing options to suit various operating environments:
Standard Open Design: Allows for custom sealing solutions based on application requirements1
Optional Seals: Can be equipped with contact or non-contact seals (RS or ZZ type) for protection against contaminants
Lubrication Retention: Precision machining ensures minimal lubricant leakage while maintaining optimal lubrication distribution
Corrosion Protection: Special surface treatments available for applications in humid or chemically aggressive environments
Cleanroom Compatibility: Ultra-clean manufacturing processes make this bearing suitable for sensitive applications

Dimensions:
The RU8509TM features precise dimensional characteristics:
Bore Diameter: 44.45mm (1.75 inches) - precision ground to h6 tolerance
Outside Diameter: 85mm - machined to exacting standards for perfect housing fit
Width: 28.575mm (1.125 inches) - optimized for space-constrained applications

Load capacity:
The RU8509TM delivers exceptional load handling characteristics:
High Radial Capacity: Line contact design provides superior radial load capacity compared to ball bearings2
Moderate Thrust Capacity: Can accommodate limited axial loads in one direction (NJ design variant)2
Impact Resistance: Robust construction withstands shock loads and vibration
Speed Performance: Suitable for high-speed applications with proper lubrication

Temperature resistance:
The RU8509TM performs reliably across a wide temperature range:
Standard Operating Range: -30°C to +120°C with conventional greases
Extended Range: -40°C to +150°C available with special lubricants and materials
High-Temperature Option: Up to +200°C with high-temperature steel and lubricants
Thermal Stability: Maintains dimensional stability across the operating range
Temperature Monitoring: Compatible with temperature sensors for critical applications
Heat Dissipation: Optimized internal clearances prevent excessive heat buildup
