Construction Features and Mechanical Design<\/h3>\n

The pump support belongs to the Borelli technical series designed for mechanical coupling with Group 2 hydraulic pumps. The assembly is built around a machined housing with standardized mounting hole spacing: two 11 mm diameter through-holes (100 mm center-to-center spacing across an 86 mm width) and M10 threaded holes with 71.4 mm center-to-center spacing. The main housing has a depth of 47 mm, with a 25 mm thick mounting flange and a centering dimension of 34.9 mm.<\/p>\n

The drive shaft features a 17×14 female internal spline profile compliant with UNI 5482 (geometric concentricity tolerance of 0.08 relative to datum A). The external end features a standard taper with a Woodruff keyway (3×6.5 mm) and an M12x1.5 metric threaded end, secured by an M12 nut and a 12.5 mm diameter washer. The shaft projects 40.4 mm beyond the mounting face, resulting in an overall assembly length of 87.4 mm.<\/p>\n

Mechanical Load Support System<\/h3>\n

Rotation and dynamic load distribution are managed by two 6006 radial ball bearings. The bearing assembly is axially secured by two UNI 7435-30 Seeger retaining rings and completed by a positioning and centering ring. This dual-bearing configuration enables the support to withstand external stresses with a specified maximum permissible load of 100 daN (with a radial load acting on the shaft of 90 daN).<\/p>\n

Sealing and Protection System<\/h3>\n

The integrity of the assembly and protection against leakage and contaminants are ensured by a dual-barrier sealing system: a 30x40x7 mm radial shaft seal mounted on the shaft and a static O-ring seal positioned at the rear flange interface.<\/p>\n
