The Borelli SAE Profile Splined Sleeves – 34100 Series are essential components for power transmission in complex industrial hydraulic systems. Technicians and engineers use these components to connect hydraulic motors safely and efficiently to the rest of the system, ensuring maximum mechanical efficiency while minimizing energy losses.<\/p>\n

Construction Features and Materials<\/h3>\n

The Borelli SAE Profile Splined Sleeves – 34100 Series are manufactured from UNI 16CrNi4\/Pb steel subjected to specific heat treatments. This material provides high resistance to wear and continuous torsional stresses during normal operation. In addition, for hydraulic applications requiring even greater load-bearing performance, the general catalogue includes coupling half variants manufactured from quenched and tempered UNI 38NiCrMo4\/Pb steel. These specific versions undergo a rigorous nitriding process, technically known as Tenifer, which increases mechanical strength to values ranging from 95 to 105 kg\/mm\u00b2.<\/p>\n

Spline Profile and Mechanical Coupling<\/h3>\n

The technical design of these sleeves focuses on seamless integration with the Danfoss range of hydraulic motors. The main mechanical interface uses the SAE 6B spline profile, an industrial standard that ensures extremely precise engagement and uniform load distribution across the spline teeth. The internal and external geometries are machined to tight mechanical tolerances to prevent excessive play, premature wear or critical misalignment during intensive machinery operation.<\/p>\n

Variants and Dimensional Specifications<\/h3>\n

The series is divided into two main configurations to meet different engineering and machinery mounting requirements. The first configuration includes a keyway (dimension C) and features external diameters (De) ranging from 40 mm to 50 mm, internal diameters (Di) from 25 mm to 32 mm and overall lengths (L) of 43 mm or 50 mm. The second configuration features an SAE 6B splined connection, with a standardized external diameter (De) of 40 mm and compact lengths (L) of 37 mm and 45 mm. Both solutions provide direct compatibility with Danfoss motors, facilitating maintenance, design and replacement operations in modern hydraulic systems managed and distributed by Lube Team Hydraulic.<\/p>\n
