Spline half-coupling

The spline coupling or spline half-coupling with internal or external teeth have the function of mechanically connecting, for example, a hydraulic pump group 2 or group 3 with a multiplier. The fluted sleeve is widely used in the agricultural world with the PTO and a hydraulic pump. They can be fixed on hydraulic motors for agricultural and TP tractors. The groove makes it possible to go from a high power to a relatively low speed. There is also the spline sleeve in mechanical clutches coupled to hydraulic pumps. This economical solution remains reliable and requires very little maintenance.

Hydraulic Spline Couplings and Splined Couplings Connections

Spline Couplings and Hydraulic Pump Coupling

Splined Bushings Spline Couplings: Function

Splined hubs or couplings with internal or external teeth serve the purpose of mechanically connecting, for example, a hydraulic pump group 2 or group 3 with a multiplier. The splined bushing is widely used in the agricultural world with the power take-off and a hydraulic pump. They can be attached to hydraulic motors for agricultural and construction tractors. The spline allows for a significant power reduction to a relatively low speed. Splined bushings are also found in mechanical clutches coupled to hydraulic pumps. This cost-effective solution remains reliable and requires very little maintenance.

Splined Hub: Machining

The splined couplings offered by OCGF have internal teeth and a smooth exterior. These hydraulic bushings are components of the drive shaft and are made of high-quality materials. These stainless steel fittings are highly resistant. They are produced from advanced materials using modern equipment. The mechanical splined bushings are machined with a high level of craftsmanship and in strict compliance with industry standards to ensure reliability and durability over time.

Coupling spline: Splines and Dimensions

The dimensions of a spline coupling sleeve correspond to the specific description of the inner and outer splines of a hydraulic bushing.

Inner Splines


  • The numbers 16/32" indicate the pitch and diameter of the base circle of the spline.
  • DP refers to "diametral pitch," a measure used to describe the size and geometry of the splines.
  • A LxH - DIN 5482 (A 14/17 - DIN 5482): This indicates that the inner spline of the splined bushing has a specific shape designated by "A" according to DIN 5482 standards.
  • The dimensions of this spline are 14mm in width and 17mm in height.
  • W20x1.25x14x9H - DIN 5480: This refers to another inner spline of the splined bushing.W20x1.25x14x9H" is a specific designation according to DIN 5480 standards. These numbers represent the characteristics of the spline: "W20" denotes the spline profile, "1.25" is the spline module, "14" indicates the base diameter, and "9H" refers to the radial play of the spline.
Outer Splines

B 25x22 - DIN 5482:

  • "B" is a specific designation for the spline shape according to DIN standards.
  • "25x22" indicates the dimensions of the spline, where "25" represents the width, and "22" represents the height of the spline.
  • DIN 5482 is the specific technical standard that defines the dimensions and specifications for this type of spline.
  • Smooth: No outer splines

PTO Shaft Coupling

A PTO spline coupling is a mechanical component used in power transmission systems in agriculture and other related industries. It is typically used to connect and transmit power from a power take-off shaft (PTO) to another component or equipment.

The PTO spline coupling is a mechanism located at the rear of tractors and other agricultural vehicles, allowing the transfer of power from the engine to the attached tools and equipment. The PTO shaft coupling is a key element of this power transmission system.

The PTO shaft coupling is designed with splines on the outside that match those of the PTO shaft coupling. It fits onto the power take-off and locks in place using a locking mechanism, ensuring a secure and robust connection.

Once the PTO spline coupling is connected to the vehicle's power take-off, it enables the transmission of power from the engine to the tools or equipment attached to it. This can include equipment such as grinders, mixers, mowers, pumps, trailers, and many more.

Spline Shaft Coupling : Reliable Power Transmission and Easy Disassembly

OCGF also markets coupling spline, which are essential mechanical elements for power transmission between two rotating shafts. Offering a combination of robustness, flexibility, and ease of use, they provide an effective solution for a wide range of industrial and agricultural applications.

The coupling spline attaches to the shafts through splines and a key, ensuring a strong connection and precise rotational torque. Its design allows for easy assembly and disassembly, facilitating maintenance and component replacement.

Advantages of Spline Shaft Coupling

  • Reliable power transmission: The splined system and key ensure optimal torque transmission.
  • Ease of installation and maintenance: Easy disassembly allows for quick maintenance and repairs.
  • Robust and durable: Manufactured in steel or cast iron, splined bushings resist harsh environments.
  • Versatility: Available in a wide range of sizes and materials to meet various needs.

Types of Splined Bushings for Keys Straight splined bushings

The solution standard for most applications : 

  • Flanged splined bushings: Offer better resistance to axial forces.
  • Expansion splined bushings: For quick assembly and disassembly without shaft disassembly.
  • Compression splined bushings: Particularly suitable for applications with strong vibrations.

Choosing the Right Spline Shaft Coupling

Several factors need to be considered, such as:

  • Shaft diameters
  • Torque to be transmitted
  • Rotational speed
  • Environmental conditions
  • Budget
