013.50.1025.03K 1200 mm 880 mm 1130 mm 1025 mm 130 mm Frequently Asked Questions about 013.50.1025.03K Four-Point Contact Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the 013.50.1025.03K Four-Point Contact Ball Slewing Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Sourcing 013.50.1025.03K directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Four-Point Contact Ball Slewing Bearings.
To ensure optimum performance of CHG Bearing 013.50.1025.03K 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 880 mm bore. For the 1200 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
To extend the trouble-free lifespan of CHG Bearing 013.50.1025.03K, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
