Description

ISB inner rings offer the possibility to adopt more advantageous and correct solutions when the shaft cannot be used as a rolling groove for the bearing. Inner rings are available with different width and in two different series: IR and LR. IR are well finished whereas LR are cheaper and usually combined with bearings open or closed end, both rings are supplied with a chamfer to facilitate their mounting. IR rings are available in different versions as per customers requirements: greater precision (P5 and P6 tolerance class), C2-C3-C4 radial clearance and with lubrication hole. LR rings are hardened and well finished even if lateral surfaces are not grinded; special executions are not available, only standard types.
