Enduro Bearings Deep Groove Ball Bearing 61902 15 mm x 28 mm x 7 mm

The 61902 Deep Groove Ball Bearing by Enduro Bearings with dimensions 15 mm x 28 mm x 7 mm

The 61902 steel ball bearing from Enduro Bearings has an inner diameter of 15 mm, an outer diameter of 28 mm and a width of 7 mm. It is fitted with an LLU double lip seal on one side and a thinner LLB seal on the other. In order to meet the ABEC-5 standard, this bearing must meet extremely high requirements for roundness of the bearing balls, tolerances of the inner and outer diameters, alignment of the running surfaces as well as low noise. Like all ABEC-5 bearings from Enduro Bearings, it features R64 hardened grade 5 chrome steel bearing balls, making it suitable for high-precision use. The balls move in vacuum-manufactured run surfaces made of 52100 carbon chrome steel, which are particularly sturdy and durable. The nylon graphite ball bearing cages have virtually no friction, and ensure constant double-sided supply of Rheolube 374A grease.
