Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 011.60.2500.12, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
To safeguard CHG Bearing 011.60.2500.12 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (2325 mm x 2678 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Model 011.60.2500.12 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 2325 mm) and steep thermal gradients between inner and outer rings.
The Open Type engineered for 011.60.2500.12 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
