Deep Groove Ball Bearings FAG 6011 -RSR

The 6011-RSR deep groove ball bearing from FAG Wälzlager, measuring 55x90x18 mm and featuring a single-sided RSR seal, offers targeted protection against contamination whilst allowing for flexible relubrication.

The 6011 -RSR deep groove ball bearing is a single-row rolling bearing from FAG Wälzlager, manufactured to standard tolerance class P0/PN or ABEC 1. It has a 55 mm bore, an outer diameter of 90 mm and a width of 18 mm. The design, made from standard rolling-bearing steel 100Cr6 with a sheet steel cage, primarily accommodates radial and axial forces in both directions. Thanks to its standard radial clearance, this bearing is suitable for precise shaft guidance at conventional operating temperatures.

What is the 6011-RSR deep groove ball bearing suitable for in practice?

Design engineers and maintenance personnel primarily use the 6011 -RSR deep groove ball bearing in rotating assemblies subject to contamination on one side only. The dimensions, designed for a 55 mm shaft, meet typical requirements in general mechanical engineering. Thanks to the flangeless cylindrical outer ring, the bearing fits precisely into standard housings. It is suitable for installations where one side needs to remain protected from dust, whilst the open opposite side allows lubricant to enter via the internal space.

What is the function of the single-sided RSR seal on this bearing?

The RSR design features a single-sided seal that repels dirt and moisture on the outer side. At the same time, the other side of the bearing remains open, allowing lubricating oil or grease from inside the housing to reach the rolling elements unhindered. When designing the system, take into account the permissible temperature range of -30 to +100 degrees and the standard radial bearing clearance. This requires the bearing seats to be precisely aligned to prevent stress build-up during operation.
