SL11930 Three Row Full Loaded Cylindrical Bearing 150*210*88mm No Cage Heavy Industry Equipment Bearing GQZ
Product Overview
SL11930 is a three-row full complement cylindrical roller bearing with dimensions 150*210*88mm, designed without a cage and fully filled with cylindrical rollers to maximize load capacity. It belongs to SL11 series fixed-end bearing, capable of bearing huge radial loads and limited bidirectional axial loads simultaneously. The open structure fits circulating oil lubriion for heavy industrial continuous operation; optional 2RS double rubber seals are available for dusty, muddy harsh working environments. Inner and outer rings are made of high-purity GCr15 bearing steel with full heat treatment for high hardness and wear resistance. Dense roller arrangement ensures uniform stress distribution and strong impact resistance, widely used as core heavy-duty rotary components for steel mills, mining equipment and wind power machinery.
