Pump Bearing Supports

Hydraulic Gear Pump Bearing Supports

Flowfit supplies a range of robust hydraulic gear pump bearing supports for protecting pump shafts and bearings in mechanically driven hydraulic systems. Installed between the drive arrangement and the hydraulic pump, a bearing support helps absorb external radial loads before they are transferred to the pump.

These components are particularly important when a hydraulic pump is driven by a V-belt pulley, chain drive, coupling or other mechanical transmission. By supporting the drive shaft independently, they can help reduce premature pump wear and improve the reliability of the complete hydraulic system.

What Does a Pump Bearing Support Do?

A hydraulic gear pump is primarily designed to transmit rotational power through its input shaft. External loads created by belt tension, pulleys or misaligned drive components can place additional stress on the pump shaft and internal bearings.

A pump bearing support provides an additional supported shaft and bearing arrangement, helping to carry these external radial loads while maintaining accurate alignment between the drive and the hydraulic pump.

When Is a Gear Pump Bearing Support Required?

A bearing support should be considered whenever the pump is exposed to significant side loading or is not connected directly to the drive source through a correctly aligned flexible coupling.

• V-belt and pulley drives - Helps absorb belt tension and radial loading.
• Chain-driven systems - Provides additional support for loads created by the chain and sprocket.
• Engine-driven hydraulics - Suitable for auxiliary hydraulic systems powered by an engine or motor.
• Agricultural machinery - Supports pumps used on tractors, trailers and mobile equipment.
• Industrial and mobile hydraulics - Helps protect pumps operating in demanding mechanical drive arrangements.

Available Pump Bearing Support Options

Our range includes bearing supports for different hydraulic pump groups and drive arrangements. Available options include single-bearing and twin-bearing designs, along with a selection of shaft sizes and mounting configurations.

Selected products are manufactured by Borelli, while other models are supplied under their recognised KS product references. Check the individual product specifications carefully to confirm the pump group, shaft dimensions and bearing arrangement required for your installation.

Key Features of Our Pump Bearing Supports

• Helps absorb external radial loads from pulleys, belts and chain drives

Choosing the Correct Pump Bearing Support

When selecting a bearing support, check the required pump group, shaft diameter, shaft type, mounting dimensions, bearing arrangement, maximum speed and permitted radial load. The drive pulley, coupling or sprocket must also be correctly aligned to avoid unnecessary stress and premature wear.

Where a product is intended as a replacement for an existing bearing support, compare all dimensions and operating specifications before installation rather than relying only on the product reference.
