Ball Bearing 20x47x31mm UC204/UC204-12 Vikye Insert Bearings

Description

Product Overview

The Vikye UC204/UC204-12 ball bearing is engineered to meet the demanding requirements of modern industrial and scientific applications. With dimensions of 20x47x31mm (approximately 0.79×1.85×1.22 inches) and a weight of just 10.55 ounces, this insert bearing delivers a perfect balance between size, weight, and performance. Constructed from premium-grade ball bearing steel, the bearing exhibits high hardness and superior wear resistance, ensuring a long service life even under continuous operation.

Each bearing features a compact, precision‑machined design that reduces overall assembly space while maintaining optimal load‑carrying capacity. The steel balls are uniformly distributed within the inner and outer races, providing smooth rotational motion and minimizing vibration. The UC204 model is compatible with a broad spectrum of machinery, from small hand tools to larger power transmission equipment, making it a versatile component for engineers and technicians alike.

Key specifications include a standard bore size of 20mm, an outer diameter of 47mm, and a width of 31mm. The bearing conforms to ISO standards for insert bearings, guaranteeing interchangeability and ease of replacement. Its robust construction also offers resistance to corrosion and temperature fluctuations, allowing reliable operation in harsh environments.

Usage

Designed for a wide variety of machinery and tools, the UC204 bearing excels in applications where precision and durability are paramount. It is commonly employed in gearboxes, motor shafts, conveyor systems, and robotic joints, where reducing friction directly translates to increased efficiency and lower energy consumption. The bearing’s compact footprint enables installation in confined spaces, such as compact CNC machines, portable power tools, and custom‑built automation rigs.

Beyond industrial settings, the bearing is suitable for hobbyist projects, including 3D printer upgrades, drone motor assemblies, and DIY mechanical prototypes. Its high‑strength steel composition ensures that even in high‑speed or high‑load scenarios, the bearing maintains stability and prevents premature wear. Users can expect consistent performance whether the bearing is operating at moderate speeds in a workshop or at high RPMs in a production line.

Installation is straightforward thanks to the standardized dimensions and the inclusion of a retaining sleeve that simplifies mounting onto shafts and housings. The bearing’s design also facilitates easy removal for maintenance or replacement, reducing downtime and maintenance costs. Whether you are an OEM supplier, a maintenance engineer, or a maker building a custom device, the UC204 bearing provides the reliability needed for continuous operation.
