Product Description

The U205 maintenance-free bearing is a robust 140mm self-lubricating bearing designed for industrial applications requiring durability and reduced upkeep. With a 25mm inner diameter and 24mm width, it features a steel-backed polymer composite layer for frictionless operation under heavy loads (static: 47kN, dynamic: 31kN). Operating within -40°C to +200°C, this U205 bearing 140mm variant eliminates external lubrication needs, making it ideal for high-speed machinery, conveyor systems, and automotive components. Its self-lubricating design ensures consistent performance in dusty or humid environments while minimizing wear. Key advantages include extended service life, zero maintenance, and compatibility with moderate axial/radial loads, though it is not recommended for extreme chemical exposure or ultra-high-temperature scenarios exceeding material limits.
