Borelli Splined Coupling Halves – 13000 Series
The Borelli Splined Coupling Halves – 13000 Series are essential components for hydraulic applications and fluid contamination control. Manufactured entirely from heat-treated UNI 16CrNi4/Pb steel, they ensure structural reliability. Featuring DIN 5482A external spline profiles and DIN 5482B internal spline profiles, they are compatible with pump types ranging from 20-35 to 186.
The available product codes are: 13001, 13002, 13003, 13004, 13005, 13006, 13007, 13008, 13009, 13010.
The Borelli Splined Coupling Halves – 13000 Series are developed to meet the requirements of industries involving hydraulic components and fluid contamination control. The standard construction of these components uses UNI 16CrNi4/Pb steel, which undergoes specific heat treatments to optimize its operating performance. When coupling halves are identified by an asterisk, they are manufactured from quenched and tempered UNI 38NiCrMo4/Pb steel. This variant undergoes a nitriding treatment, known as Tenifer, which provides the component with a mechanical strength ranging from R = 95 to 105 kg/mm².
The mechanical interface of the 13000 Series is defined by strict geometric standards. The external spline profile complies with DIN 5482A, featuring dimensional configurations of 48×44, 58×53 and 72×66, corresponding to 23, 27 and 33 teeth respectively. The internal spline profile complies with DIN 5482B, offering dimensions ranging from 25×22 (14 teeth) to 50×45 (24 teeth), ensuring precise tolerances for the insertion of driving or driven shafts.
The series is designed for use with various types of hydraulic pumps. Supported models include pump types 20-35, 50, 75, 105, 140 and 186. In terms of dimensions, the overall length (dimension L) of the coupling halves ranges from a minimum of 40 mm for product code 13001 to a maximum of 68 mm for product code 13010. The largest external diameter (dimension A) ranges from 47.5 mm to 71.3 mm, while the coupling dimension (dimension C) ranges from 25 mm to 50 mm.
Distributed by Lube Team Hydraulic S.r.l., these coupling halves are intended for demanding industrial applications where precise rotational motion is essential. The components are designed for integration into complex systems, providing a stable and durable connection for hydraulic mechanical assemblies.
