Description

Standard light series ball slewing ring square section with internal gear with an average raceway diameter from 411 to 1,091 mm These slewing rings are not recommended for hanging loads. Vertical use must be limited due to clearance. These ball slewing bearings are also available without drilled holes, with identical part numbers, but differentiated by the last two characters: • - 00: without fastening holes • - 01: standard drilling Light series slewing rings with square sections have a slightly higher load capacity than the ones with a L-shaped profile. There are 3 different gear run-outs levels for each family (standard, low, very low).
