Operating Principle<\/h3>\n

The mechanical clutch series includes both bidirectional and unidirectional models. During normal operation, coupling with hydraulic pumps requires a specific technical condition: pump engagement and disengagement must only be performed with the directional control valve in the unloading position. Under these conditions, the rotational speed during engagement must not exceed 1800 rpm for standard versions. When using the reversible version, the maximum permitted engagement and disengagement speed is reduced to 1000 rpm, protecting the dog clutch teeth and extending the service life of the assembly.<\/p>\n

Technical Specifications and Performance<\/h3>\n

The Borelli Group 3.5-4 Mechanical Dog Clutch – 30500 Series is designed for heavy-duty applications. The device handles a nominal torque of 58 daNm and is rated for a maximum rotational speed of 2700 RPM. The assembly can transmit a maximum power of 60 kW and withstand an axial load of 260 daN. These technical specifications make the 30500 Series suitable for high-performance configurations.<\/p>\n

Lubrication Guidelines and Operating Temperatures<\/h3>\n

Maintaining clutch efficiency requires strict adherence to a lubrication protocol. The specified lubricant is SAE 90 oil, whose level and condition must be monitored over time. A complete oil change must be performed every 12 months of continuous operation. The component is designed to withstand a specific temperature range: the maximum permitted operating temperature is +80°C, while the minimum operating temperature is -10°C.<\/p>\n

Construction Features and Spare Parts<\/h3>\n

The internal assembly incorporates high-strength splined input and output shafts, supported by precision bearings (16012, 3212 and 6203 series) housed within a robust cast housing. Sealing is ensured by dedicated oil seals (60x75x8) and O-rings (109 and 113). The system includes oil level, breather and drain plugs with standard threads (1\/8″ G and 3\/8″ G) to facilitate inspections.<\/p>\n

Rotation Variants and Compatible Flanges<\/h3>\n

The 30500 Series is available in three basic configurations based on the direction of rotation: code 30500 identifies the reversible version, 30501 the right-hand version, and 30502 the left-hand version. The system is complemented by an extensive range of adapter flanges (30400 family), enabling compatibility with various standards, including Group 2, Group 3, Group 3.5, Group 4, Bosch pumps, SAE A, B and C profiles, and L.G. and Ultra 3PL Dowty configurations.<\/p>\n
