132.50.3150.12K1 1725 mm 2868 mm 1950 mm 3432 mm 270 mm Frequently Asked Questions about 132.50.3150.12K1 Three-row Cylindrical Roller Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 132.50.3150.12K1 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (2868 mm x 3432 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
For international ocean and air freight, CHG Bearing packs 132.50.3150.12K1 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
Standard batches of CHG Bearing 132.50.3150.12K1 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 132.50.3150.12K1 Three-row Cylindrical Roller Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 2868 mm bore. For the 3432 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
