Pinions & Drive shafts

We manufacture a wide range of high-performance gears engineered for durability, precision, and efficiency across applications

Pinion with Shrink Fitted Shaft

A pinion with a shrink-fitted shaft is a precision-engineered assembly where the pinion gear is mounted onto the shaft using an interference fit achieved by thermal expansion. The shaft is heated or the gear is cooled to allow insertion, creating a tight, secure connection once temperatures equalize. This method ensures excellent torque transmission without the need for additional fasteners, reducing the risk of slippage under heavy loads.

Pinion Gear

A pinion gear is the smaller of two meshing gears, often paired with a larger gear called a spur gear or rack in rack-and-pinion systems. It transmits rotational motion and torque, typically converting rotational movement into linear motion or altering speed and direction in machinery. Pinion gears are widely used in vehicles (steering systems, differentials), industrial machines, and mechanical tools. Made from materials like steel, brass, or hardened alloys, they are designed for durability and smooth operation.

Pinion Shaft

A pinion shaft is a mechanical component that transfers rotational motion and torque in machinery, commonly found in gear systems, automotive differentials, and industrial equipment. It typically consists of a shaft with a pinion gear mounted on it, which meshes with a larger gear (ring gear) to change speed, direction, or torque. Pinion shafts are designed for strength and durability, often made from hardened steel to withstand heavy loads and friction.

Large Pinion Gear

A large pinion gear is a small driving gear that meshes with a larger gear or rack, but in this context, “large” refers to its size compared to standard pinions. It is designed to transmit rotational motion and torque efficiently within heavy-duty machinery. Large pinion gears are commonly used in industrial equipment, mining machinery, rolling mills, and cranes, where they handle high loads and require durability. Made from hardened steel or alloy materials, they offer precision, wear resistance, and smooth operation.

Large Girth Gear

A large girth gear is a heavy-duty, circular gear with a wide diameter used in industrial machinery such as ball mills, rotary kilns, and crushers. It transmits torque from the drive system to the rotating drum, ensuring smooth, efficient, and reliable operation under high-load conditions.
