Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 012.60.2000.12 with a precision bore diameter (d) of 1825 mm, an outside diameter (D) of 2178 mm, and a nominal ring width (B) of 144 mm. This configuration yields an effective cross-sectional wall thickness of 176.5 mm and an envelope ratio (D/d) of 1.19, delivering compact rigidity for OEM machinery housings.
Standard batches of CHG Bearing 012.60.2000.12 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.
To ensure optimum performance of CHG Bearing 012.60.2000.12 Four-Point Contact Ball Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 1825 mm bore. For the 2178 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 012.60.2000.12, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
