FKG 3202-2RS 5202-2RS Angular Contact Ball Bearing 15x35x15.9mm Sealed

Description

Product Overview

The FKG 3202-2RS 5202-2RS angular contact ball bearing is engineered to meet the demanding requirements of modern industrial equipment. With an inner diameter of 15 mm, an outer diameter of 35 mm, and a width of 15.9 mm, the bearing provides a compact footprint while maintaining high load capacity. The bearing utilizes high‑quality chrome steel balls that are precision‑ground to achieve tight tolerances, ensuring smooth rotation and minimal vibration. A double‑sided rubber seal is integrated on both inner and outer rings, creating a barrier against dust, moisture, and other contaminants that could compromise performance. The seals are designed to be flexible yet durable, allowing for easy installation while maintaining long‑term sealing integrity. FKG’s manufacturing process includes rigorous heat‑treatment cycles that enhance hardness and wear resistance, extending the service life of the bearing under continuous operation. The bearing conforms to ISO 281 standards for dimensional accuracy and load rating, providing confidence in its reliability across a range of applications. Its design also facilitates easy mounting on standard shafts and housings, reducing downtime during maintenance or replacement procedures.

In addition to its mechanical attributes, the bearing is supplied in a compact packaging that protects the product during transit and storage. The package dimensions of 2.01 × 1.97 × 0.75 inches and a weight of 2.4 ounces make handling straightforward for warehouse personnel. The product is identified by the model numbers 3202-2RS and 5202-2RS, reflecting its interchangeable nature within FKG’s catalog. This interchangeability simplifies inventory management for distributors and end‑users alike, as the same bearing can be used in multiple machine configurations without the need for additional part numbers. The bearing’s performance is further validated by a five‑star customer rating, indicating high satisfaction among users who have deployed it in critical applications.

Material selection plays a crucial role in the bearing’s durability. The outer and inner rings are fabricated from high‑carbon alloy steel, which offers a balance of strength and toughness. The steel is subjected to a controlled quenching and tempering process that yields a surface hardness of approximately 60 HRC, providing resistance to surface fatigue and spalling. The rubber seals are composed of a synthetic elastomer that retains its elasticity over a wide temperature range, from -30 °C to +120 °C, ensuring consistent sealing performance even in harsh environments. This combination of robust materials and precise engineering results in a bearing that can sustain high rotational speeds, typically up to 12,000 rpm, without compromising stability or accuracy.

From a design perspective, the angular contact geometry allows the bearing to accommodate both radial and axial loads simultaneously. This dual‑load capability is essential for applications such as spindle drives, gearboxes, and high‑speed compressors where thrust forces are present alongside radial forces. The contact angle of the bearing is optimized to provide a high axial load rating while maintaining low friction coefficients, contributing to energy efficiency and reduced heat generation. The bearing’s internal clearance is carefully controlled to balance stiffness and flexibility, enabling it to adapt to thermal expansion without excessive preload. These engineering choices make the bearing suitable for precision equipment that demands tight tolerances and consistent performance over extended operating periods.

Quality assurance is integral to FKG’s production philosophy. Each bearing undergoes a series of non‑destructive tests, including ultrasonic inspection and magnetic particle testing, to detect internal defects before shipment. Dimensional inspections are performed using coordinate measuring machines (CMM) to verify compliance with specified tolerances. The final product is packaged with a protective sleeve and a moisture‑absorbing desiccant to safeguard against environmental exposure during storage. Documentation accompanying the bearing includes a detailed data sheet outlining dimensions, load ratings, material specifications, and recommended lubrication practices. This comprehensive information empowers engineers to make informed decisions when integrating the bearing into their designs, ensuring optimal performance and longevity.

Usage

The FKG angular contact ball bearing is ideally suited for high‑speed spindle applications in CNC machining centers, where precise positioning and rapid acceleration are required. Its ability to handle combined radial and axial loads enables it to support cutting tools that generate significant thrust forces while maintaining rotational accuracy. In robotic arms, the bearing provides smooth articulation at joint interfaces, allowing for repeatable motion paths and reduced wear on adjacent components. The double‑sided rubber seals protect the internal rolling elements from dust and oil splatter commonly encountered in manufacturing floors, extending service intervals and minimizing unexpected downtime.

Industrial compressors benefit from the bearing’s high‑speed capability and robust sealing, as the rotating shafts often operate at speeds exceeding 10,000 rpm. The bearing’s angular contact design ensures that axial thrust generated by the compressor pistons is effectively absorbed, preventing shaft deflection and maintaining balance. In medical imaging equipment, such as MRI and CT scanners, the bearing’s low vibration characteristics contribute to image clarity by reducing mechanical noise that could interfere with sensor readings. The bearing’s compact dimensions allow it to be integrated into tight mechanical envelopes without sacrificing performance.

Automated assembly lines frequently employ conveyor systems that rely on precision bearings to drive rollers and gear trains. The FKG bearing’s durability under continuous operation makes it a reliable choice for these high‑duty environments. Its resistance to contamination is particularly valuable in facilities where particulate matter, such as metal shavings or plastic dust, is prevalent. The bearing can also be used in aerospace ground support equipment, where reliability and ease of maintenance are critical for ensuring aircraft turnaround times remain within schedule.

For renewable energy applications, such as wind turbine gearboxes, the bearing’s ability to sustain high axial loads and operate under variable temperature conditions contributes to the overall efficiency of power generation. The rubber seals mitigate ingress of moisture and salt, which are common in offshore installations, thereby protecting the bearing from corrosion. In marine propulsion systems, the bearing’s corrosion‑resistant materials and sealing technology help maintain performance despite exposure to saline environments.

When selecting lubrication for the FKG angular contact bearing, engineers should consider the operating temperature range and load conditions. Synthetic grease with high temperature stability is recommended for applications where the bearing may experience temperature spikes, while oil lubrication can be advantageous in high‑speed scenarios to reduce friction further. Proper lubrication, combined with the bearing’s inherent design features, ensures that the bearing delivers consistent performance throughout its service life.
