Heavy-Duty Trailer Turntables for Agricultural & Commercial Vehicles

DescriptionA trailer ball bearing turntable plays a vital role in linking tractors, trailers, or trucks, allowing smooth turning while effectively transferring towing forces. Our turntables find extensive applications across heavy-duty full trailers, light truck trailers, agricultural trailers, and various specialized vehicles and industrial equipment. Since 1999, WONDEE Autoparts has been pioneering in this field by introducing China’s first trailer turntable designed specifically for the international market.Product Highlights and Technical DetailsCrafted to automotive-grade standards, our turntables deliver reliable performance backed by rigorous quality control.Quality Management: We adhere to the IATF16949:2016 automotive quality system and ISO9001:2015 standards.Compliance: All products meet or exceed JT/T651-2006 and LY/T1292-1998 technical requirements.Materials: Manufactured using QT500-7 ductile cast iron, ensuring tensile strength above 500 MPa for enhanced durability.Clearances: Radial clearance is controlled within ≤ 0.65 mm, tighter than the European benchmark of 0.70 mm; axial clearance is ≤ 0.90 mm, also better than the European standard of 1.00 mm.Precision: Dimensional deviations in height and diameter remain within ±0.5 mm, far surpassing the European tolerance of ±3.0 mm.Surface Quality: Ball rail surface roughness measures Ra 0.8 μm, with overall surface roughness at Ra 3.2 μm; flatness is maintained at ≤ 0.15 mm.Dust Protection: Equipped with a dual-stage dust-proof design to ensure long-lasting operation under harsh conditions.Comprehensive Turntable InformationWONDEE offers a variety of turntable series to meet your needs.SeriesUA type, UB type, U type, ZA type, ZB type, UC typeAxial Capacity2 Ton ~ 22 TonSize/Diameter300 mm ~ 1200 mmHeight45 mm ~ 94 mmBearing Ball RaceSingle-row ball race, double-row ball raceMounting HoleDrilled or undrilledStandardsIATF16949, ISO9001-2015, JT/T651-2006 & LY/T1292-1998Turntable Models and ReplacementsWe provide a wide selection of turntables, including models that serve as replacements for major brands like JOST, Buer, and BPW.UA Type Turntables with Single-Row Ball RaceItem No.ØA (mm)C (mm)Tonnage (ton)ReplacementTS1000-92UA0110009210KLK SO 1000-24TS1000-90UA0110009010KLK HE 1000-22TS1090-80UA011090806.5KLK HE 6TS880-80UA01880805KLK HE 5ZA Type TurntablesItem No.ØA (mm)C (mm)Tonnage (ton)ReplacementTS1050-56ZA011050565KDL 900-6 WTS750-56ZA01750563KDL 900-3 WTS520-56ZA01520562KDL 900-1 WZB Type TurntablesItem No.ØA (mm)C (mm)Tonnage (ton)ReplacementTS950-58ZB01950584.5KLK 950NTS850-52ZB01850523.5KLK 850NTS750-52ZB01750523KLK 750NTS500-52ZB01500522KLK 500NManufacturing and Quality ControlOur factory occupies over 25,000 square meters and is equipped with more than 50 sets of machinery. We employ over 70 people, including 6 engineers. Our production process is meticulously managed, from mould making to final warehousing. Quality control includes metallographic analysis, radial and axial clearance measurements, and pressure and tensile tests.The production process follows these steps: Mould Making → Sandbox Making → Steel Blank Casting → Machining → Hole Drilling → Hole Threading → Assembling → Grease Filling → Finished Product QC → Painting → Packing → Warehousing.Packing and LogisticsWe ensure proper packing, warehousing, and container loading for our trailer turntables.
