ENDURO BEARINGS Deep Groove Ball Bearing 61803 17 Mm X 26 Mm X 5 Mm

High-end product among steel bearings: the 61803 LLU/LLB ABEC 5 by Enduro Bearings
In order to meet the ABEC 5 standard, a bearing must meet extremely high requirements for the roundness of the balls, tolerances of the inner and outer diameters, alignment of the running surfaces and low noise.
ABEC 5 bearings from Enduro Bearings feature R64 hardened 5th degree chrome steel balls, making them suitable for high precision applications. They move in vacuum-formed treads made of 52100 carbon chrome steel, which are particularly resistant and durable. The nylon graphite ball bearing cages have virtually no friction, and ensure constant double-sided supply of Rheolube 374A grease.
