UNION CB-170 2RS Hub Bearing | 25x32x4 | Precision Spare PartRestore the smooth, fast-rolling performance of your bicycle´s wheels with the UNION CB-170 2RS Hub Bearing. As a critical spare part for any cyclist´s toolkit, this high-quality bearing is engineered to replace worn-out or damaged components in your hubs, bringing back that factory-fresh feel and efficiency to your ride. Whether you are performing essential maintenance, undertaking a full hub rebuild, or seeking a durable upgrade, the CB-170 is designed for reliability and longevity.Unmatched Durability and Smooth PerformanceThe core of the UNION CB-170´s exceptional performance lies in its superior construction. Both the outer and inner rings are forged from high-grade CrMo (Chromoly) steel, a material renowned for its incredible strength, fatigue resistance, and ability to withstand high-impact forces without deforming. This robust foundation ensures the bearing maintains its precise shape under the demanding loads of cycling, from intense sprints to rough trails.Complementing the tough rings are the precision-engineered CrMo steel balls. Hardened to an impressive HRC 61-66 rating, these balls are exceptionally resistant to wear and pitting. Their perfect sphericity and smooth surface minimize friction, allowing your wheel to spin freely with minimal resistance. This translates directly into a more efficient ride, where more of your pedaling power goes into forward motion. The balls are held in perfect alignment by a sturdy Steel cage, which guarantees even load distribution and prevents binding for consistent, smooth rotation mile after mile.All-Weather Protection and Certified PrecisionEngineered for real-world cycling conditions, the UNION CB-170 features a highly effective 2RS sealing system. The dual rubber seals provide a formidable barrier against contaminants like dust, mud, grit, and water, which are the primary causes of premature bearing failure. This light touch seal design is optimized to deliver maximum protection without creating excessive drag, striking the perfect balance between safeguarding the bearing´s internals and preserving rotational speed.Inside, the bearing is pre-lubricated with premium MULTEMP SRL grease from the respected manufacturer Kyodo Yushi. This high-performance fat is specifically formulated to provide long-lasting lubrication across a wide range of temperatures, resist water washout, and inhibit corrosion, significantly extending the service life of the bearing and reducing maintenance frequency.With an ABEC-3 tolerance rating, this bearing adheres to strict manufacturing standards for precision and quality. This certification ensures a reliable fit and consistently smooth performance, making it a trustworthy choice for cyclists who demand dependable components.Technical Specifications:* Model: CB-170* Type: Radial Deep Groove Ball Bearings* Measure (IDxODxW): 25x32x4 mm* Outer and Inner Ring Material: CrMo (Chromoly Steel)* Balls Material: CrMo (Chromoly Steel)* Ball Hardness: HRC 61-66* Cage Material: Steel* Sealing: 2RS - Dual Rubber Seals (light touch)* Grease (Fat): MULTEMP SRL (Kyodo Yushi)* Tolerance: ABEC-3. tradeinn Bikeinn
