Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 133.30.2130.03 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (1910 mm x 2320 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Standard batches of CHG Bearing 133.30.2130.03 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.
Yes, 100% of 133.30.2130.03 Three-row Cylindrical Roller Slewing Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
Model 133.30.2130.03 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 1910 mm) and steep thermal gradients between inner and outer rings.
