133.45.2240.03K 2479 mm 2019 mm 3185 mm 2870 mm 231 mm Frequently Asked Questions about 133.45.2240.03K Three-row Cylindrical Roller Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 133.45.2240.03K over a 2019 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
The CHG Bearing 133.45.2240.03K is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
To safeguard CHG Bearing 133.45.2240.03K against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (2019 mm x 2479 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Built for demanding industrial environments, the 133.45.2240.03K Three-row Cylindrical Roller Slewing Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
