Description
ISB slewing bearings in the ER1 standard series have one row of crossed roller bearings separated by spacers in Nylon and outer gear teeth.
They are comprised of forged rings, which are then machined to form an extremely rigid structure with square section rings.
The roller bearings rotate with very little clearance between the rollers and the raceways.
The deep fixing hole is indispensable and is always adapted for maximum performance. ISB slewing bearings in the ER1 standard series have standard market dimensions with single upper and lower lip seals in NBR. They are supplied pre-greased.
