Technical Overview of Splined Bars<\/h3>\n

The Borelli Splined Bars – 14000 Series<\/strong> are essential components in hydraulic mechanical transmission systems. These bars are part of Borelli’s extensive range of transmission components, which also includes splined coupling halves, splined couplings and chain couplings. Their precise engineering design ensures accurate and efficient power transmission. All geometric and manufacturing specifications comply with established industrial standards, allowing these bars to be integrated into complex hydraulic systems and machinery.<\/p>\n

Construction Features and Materials<\/h3>\n

The standard construction of the 14000 Series Splined Bars uses UNI 16CrNi4\/Pb steel<\/strong>. This base material undergoes appropriate heat treatments to ensure the strength and reliability required during prolonged operation. The selection of this steel alloy provides optimal structural stability for mechanical couplings.<\/p>\n

Heat Treatments and Mechanical Performance<\/h3>\n

In addition to the standard UNI 16CrNi4\/Pb version, specific options are available for applications requiring superior mechanical properties. Borelli splined components with advanced technical specifications are manufactured from quenched and tempered UNI 38NiCrMo4\/Pb steel<\/strong>. This material undergoes a surface nitriding treatment known as the Tenifer process. This treatment provides mechanical strength values ranging from R = 95 to R = 105 kg\/mm²<\/strong>, resulting in high surface hardness.<\/p>\n

Spline Profiles and Reference Standards<\/h3>\n

The coupling profile is the main functional feature of the 14000 Series. Standard machining across the entire range produces spline profiles compliant with DIN 5482B<\/strong> standards. To meet additional design requirements for hydraulic systems, the manufacturer also offers the possibility of producing these bars with alternative standardized profiles. Upon request, splined bars can be manufactured with profiles compliant with SAE 16\/32″ 12\/24″<\/strong> and DIN 5480<\/strong> standards.<\/p>\n

Dimensions and Geometric Specifications<\/h3>\n

The series offers a wide range of dimensional configurations. All bars in the 14000 Series share a fixed length (“L”) of 300 mm<\/strong>. Variations concern the spline profile, number of teeth and external diameter (“A”). The range extends from the smallest model, code 14001, featuring a 20×17 profile, 12 teeth and a diameter of 19.5 mm, to the largest model, code 14017, featuring a 100×94 profile, 44 teeth and a diameter of 99.5 mm.<\/p>\n
