Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting S16-029-20-R02 over a 85 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.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for S16-029-20-R02, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
To safeguard CHG Bearing S16-029-20-R02 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (85 mm x 178 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Standard batches of CHG Bearing S16-029-20-R02 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
